[0001] This application is a divisional application of the invention patent application filed on December 3, 2015, with application number 201510882396.1, entitled "Ultrasonic method and apparatus for processing ultrasound images". Technical Field

[0002] One or more exemplary embodiments relate to an ultrasound image processing method and an ultrasound device for performing the method, the ultrasound image processing method acquiring measurement information about an object from an ultrasound image based on user input. Background Technology

[0003] Ultrasound diagnostic equipment transmits ultrasound signals generated by the transducer of a probe to an object and receives the echo signals reflected from the object, thereby obtaining at least one image of the object's interior. Specifically, ultrasound diagnostic equipment is used for medical purposes including observing the interior of an object, detecting foreign bodies, and diagnosing damage to the object. Compared to X-ray equipment, such ultrasound diagnostic equipment offers high stability, real-time image display, and is safe due to the absence of radiation exposure. Therefore, ultrasound imaging equipment can be widely used in conjunction with other imaging diagnostic equipment.

[0004] Simultaneously, users sometimes need to measure the size, angle, area, or volume of a patient's internal organs using ultrasound images. Additionally, there are situations where users need to extract characteristics from images or graphs displayed in ultrasound images. Furthermore, users can passively obtain measurement values ​​for the items to be measured using measuring devices (such as calipers displayed in ultrasound images).

[0005] To improve diagnostic accuracy, there is a need for a method and apparatus that enhances the accuracy of measurements by accurately and easily constructing the measurements the user intends to take. Specifically, there is a need for a user interface that allows for the precise construction of measurement points in ultrasound images through simple input and the rapid acquisition of measurement information, enabling the user to obtain measurement values.

[0056] In the following description, the terminology used in the specification will be briefly defined, and embodiments will be described in detail.

[0057] In consideration of the functions related to this invention, the terminology used in this specification is that which is widely used in the current art. However, the terminology may be changed according to the intent of a person skilled in the art, precedent, or new technology in the prior art. Furthermore, some terms may be arbitrarily chosen by the applicant; in such cases, the meaning of the chosen terms will be described in detail in the specific embodiments described herein. Therefore, the terminology used in this specification should not be construed as simple naming, but should be understood based on the meaning of these terms and the overall description of the invention.

[0058] Unless otherwise specifically stated, when a component "comprises" or "contains" an element, the component does not exclude other elements, but may also include other elements. Furthermore, terms such as "...unit" and "...module" indicate a unit that performs at least one function or operation, and this unit may be implemented in hardware, software, or a combination of hardware and software.

[0059] Throughout this instruction manual, "ultrasound image" refers to an image of an object obtained using ultrasound waves. The object may refer to a part of the human body. For example, the object may include organs such as the liver, heart, brain, chest, abdomen, or a fetus.

[0060] In this specification, the term "user" may refer to a medical expert (e.g., a doctor), a nurse, a medical laboratory technician, a medical imaging expert, or an ultrasound physician, but is not limited to these.

[0061] Throughout this specification, the term "measuring device" can refer to a measurement application that receives user input for constructing the location of measurement points and provides measurement information about an object in an ultrasound image based on the location of the constructed measurement points by using an image indicating the measurement points in the ultrasound image as a medium.

[0062] The term "measuring device image" refers to a measuring point, and can also refer to an image medium of a graphical user interface used to receive user input for constructing the location of the measuring point.

[0063] For example, when an ultrasound device receives user input selecting a measuring device for measuring distance, the device can display a measuring device image indicating two measuring points in the ultrasound image. Additionally, the ultrasound device can receive user input constructing the position of the measuring points from the measuring device image. When receiving user input constructing the position of the measuring points, the ultrasound device can measure the distance based on the constructed position of the measuring points.

[0064] Embodiments will now be described in detail, examples of which are shown in the accompanying drawings. In this respect, these embodiments may take different forms and should not be construed as limited to the description set forth herein. Furthermore, components in the drawings that are not relevant to the detailed description may be omitted to ensure clarity of the inventive concept. The same reference numerals always denote the same elements.

[0065] Figure 1 This is a view illustrating an ultrasound device 1000 according to an exemplary embodiment. The ultrasound device 1000 may include a display unit 141, an input unit 103, and a controller (not shown). In addition to input devices for allowing a user to input data, the input unit 103 may also include a predetermined screen, display panel, or touchscreen 106 for visually providing information to the user, providing commands or requests to the ultrasound device 1000. Additionally, the display unit 141 may be used as a touchscreen for receiving touch input from the user.

[0066] Reference Figure 1 The display unit 141 of the ultrasound device 1000 can display the ultrasound image 130. In addition, the ultrasound device 1000 can display a measuring device image 110 for measuring an object contained in the ultrasound image 130 on the ultrasound image 130.

[0067] The ultrasonic device 1000 can determine a measuring device from a plurality of measuring devices based on user input input via the input unit 103. For example, when receiving user input to select a measuring device, the ultrasonic device 1000 can determine a measuring device from a plurality of measuring devices.

[0068] When the ultrasound device 1000 identifies a measuring device from a plurality of measuring devices, the ultrasound device 1000 may display a measuring device image 110 corresponding to that measuring device on the ultrasound image 130. For example, when the ultrasound device 1000 receives user input that selects an icon 105 indicating a length measuring device for measuring the length of a specific part of an organ or a specific bone, the ultrasound device 1000 may display a length measuring device image 110 corresponding to the length measuring device on the ultrasound image 130.

[0069] The measuring device image 110 may include a measurement point indicating the point to be measured on the ultrasound image. Additionally, the measuring device image 110 may include an adjustment section for receiving user input to adjust the position of the measurement point. In this case, the measurement point can be set separately from the adjustment section. Therefore, the user can precisely construct the measurement section without covering the measurement point on the ultrasound image with their fingers.

[0070] In addition, the ultrasound device 1000 can receive touch input to change the position of the adjustment section.

[0071] In addition, the ultrasonic device 1000 can adjust the position of at least one of a plurality of measurement points based on the position of the changed adjustment portion, and can obtain measurement values ​​based on the positions of a plurality of measurement points including at least one measurement point whose position is adjusted.

[0072] In addition, the ultrasound device 1000 can display the obtained measurement values.

[0073] When the ultrasound device 1000 receives touch input regarding the adjustment portion, the ultrasound device 1000 can change the position of the measurement point and the adjustment portion in the ultrasound image by changing at least one of the position and shape of the measurement device image 110.

[0074] For example, when receiving touch input regarding the adjustment section, the ultrasonic device 1000 can determine the position of the measurement point based on the position of the adjustment section. Furthermore, once the position of the measurement point is determined, the ultrasonic device 1000 can display the measurement point by moving it within the measurement device image. In this case, the ultrasonic device 1000 can move the measurement point by changing at least one of the shape and position of the measurement device image 110.

[0075] Furthermore, once the location of the measurement point is determined, the ultrasonic device 1000 can calculate measurement values ​​for measurement items corresponding to the measurement device selected based on the determined location of the measurement point. Measurement items may include information related to length, angle, area, and volume.

[0076] The shape of an image of a measuring device used for measuring distance can be a solid vernier caliper or a solid pair of pliers. Similarly, the shape of an image of a measuring device used for measuring area can be a solid pair of scissors. Furthermore, the shape of an image of a measuring device used for measuring contours can be a solid pen. Therefore, users can instinctively recognize the interface methods related to the measuring devices.

[0077] Figure 2 This is a flowchart of a method for obtaining measurement values ​​using an ultrasonic device 1000 according to an embodiment.

[0078] In operation S210, the ultrasonic device 1000 can display a measuring device image on the ultrasonic image. The measuring device image includes multiple measuring points and an adjustment section for adjusting the multiple measuring points. The multiple measuring points indicate the points on the ultrasonic image that will be measured.

[0079] The ultrasonic device 1000 can receive user input to select one of multiple measuring devices.

[0080] The measuring device can refer to a measurement application that receives user input regarding the location of the measurement point and provides measurement values ​​about an object in an ultrasound image based on the location of the measurement point by using an image of the point to be measured on an ultrasound image as a medium.

[0081] Ultrasonic images can be at least one selected from B (luminance) mode images, C (color) mode images, D (Doppler) mode images, M (motion) mode images, and E (elasticity) mode images. Specifically, a B-mode image represents the magnitude of the ultrasonic echo signal reflected from the object as brightness; a C-mode image represents the speed of the object's movement as color using the Doppler effect; a D-mode image represents the image of the object's movement as a spectrum using the Doppler effect; an M-mode image indicates the object's movement within a predetermined position over time; and an E-mode image represents the difference between the response when pressure is applied to the object and when no pressure is applied. However, ultrasonic images are not limited to these. Furthermore, ultrasonic images can be two-dimensional, three-dimensional, or four-dimensional images. The ultrasonic device 1000 acquires ultrasonic images by photographing the object. Additionally, the ultrasonic device 1000 can receive ultrasonic images from an external device.

[0082] The ultrasound device 1000 can determine one of the multiple measuring devices based on user input selecting one of the multiple measuring devices used to measure an object in an ultrasound image. For example, the ultrasound device 1000 can provide a measuring device selection menu for selecting one of the multiple measuring devices. The ultrasound device 1000 can simultaneously display the measuring device selection menu and the ultrasound image on one screen. Alternatively, the ultrasound device 1000 can display the measuring device selection menu on a separate screen, different from the touchscreen displaying the ultrasound image.

[0083] Additionally, the ultrasonic device 1000 can determine one of a plurality of measuring devices based on user input selecting one of a plurality of measurement items. Measurement items may include, but are not limited to, length, width, or angle. When the ultrasonic device 1000 receives user input selecting a measurement item, the ultrasonic device 1000 can determine a predetermined measuring device corresponding to the selected measurement item.

[0084] Furthermore, the ultrasonic device 1000 can determine one of multiple measuring devices based on a pattern input by the user. For example, when the ultrasonic device 1000 receives user input of touching two points on a touchscreen and dragging the two points in opposite directions, the ultrasonic device 1000 can determine an oval measuring device as the measuring device. Additionally, when the ultrasonic device 1000 receives user input of touching two points on a touchscreen and rotating one of the points, the ultrasonic device 1000 can determine a degree measuring device as the measuring device.

[0085] The ultrasonic device 1000 can display an image of the measuring device corresponding to the selected measuring device on the ultrasonic image.

[0086] A measuring device image refers to the point to be measured in an ultrasound image, and can also refer to the image medium of a graphical user interface used to receive user input for constructing the location of the measuring point. The measuring device image may be pre-stored according to the measuring device.

[0087] When the ultrasonic device 1000 determines a measuring device from a plurality of measuring devices, the ultrasonic device 1000 can display an image of the measuring device corresponding to the predetermined measuring device on the ultrasonic image.

[0088] For example, when the device is identified as a vernier caliper measuring device, the ultrasonic device 1000 can display an image of the vernier caliper measuring device on the ultrasonic image. Similarly, when the device is identified as a pliers measuring device, the ultrasonic device 1000 can display an image of the pliers measuring device on the ultrasonic image. Furthermore, when the device is identified as a scissors measuring device, the ultrasonic device 1000 can display an image of the scissors measuring device on the ultrasonic image.

[0089] The measuring device image may include multiple measurement points indicating points on the ultrasound image to be measured. The points on the ultrasound image to be measured may be points on the ultrasound image used as measurement references. The measurement points on the ultrasound image may be constructed by the user using the measuring device image. The positions of the multiple measurement points in the measuring device image may be predetermined based on the measuring device image. For example, multiple measurement points in the measuring device image with a scissor shape may be the two edges of scissors.

[0090] Additionally, the measuring device image may include an adjustment section for adjusting the position of multiple measuring points. Furthermore, the position of the adjustment section in the measuring device image may be predetermined based on the measuring device image. For example, the adjustment section in a measuring device image having a scissor shape may be the handle portion of the scissors.

[0091] The adjustment section can be configured not to overlap with multiple measurement points in the measurement device image. For example, the adjustment section can be separated from multiple measurement points in the measurement device image by a predetermined distance.

[0092] Furthermore, the ultrasound setup 1000 can display an image of the measuring device, allowing the adjustment section to be distinguished from other parts of the measuring device image. For example, the ultrasound device 1000 can display the adjustment section in a different color than other parts of the measuring device image.

[0093] The ultrasonic device 1000 can display the measuring device image semi-transparently, so that the part of the ultrasonic image that overlaps with the measuring device image is not covered by the measuring device image.

[0094] In operation S220, the ultrasound device 1000 can receive touch input that changes the position of the adjustment portion of the measuring device image on the ultrasound image.

[0095] The ultrasonic device 1000 can receive touch and drag input regarding an adjustment section in a measuring device image. For example, the ultrasonic device 1000 can receive input by touching the adjustment section with a finger or pen and dragging the finger or pen to another position on the screen while maintaining the touch state. When the ultrasonic device 1000 receives touch and drag input, the ultrasonic device 1000 can move the adjustment section along the drag.

[0096] In this case, the ultrasound device 1000 can move the adjustment portion in the measurement device image by changing at least one of the position and shape of the ultrasound image.

[0097] In operation S230, the ultrasonic device 1000 can adjust the position of at least one of a plurality of measurement points based on the position of the changed adjustment portion, and can obtain measurement values ​​based on the positions of the plurality of measurement points including the at least one measurement point whose position is adjusted.

[0098] When the position of the adjustment part changes in the ultrasound image, the ultrasound device 1000 can determine the position of the measurement point based on the position of the adjustment part.

[0099] For example, the ultrasound device 1000 can determine a measurement point as a point separated from the center point of the adjustment section by a predetermined distance. Alternatively, the ultrasound device 1000 can determine a measurement point as a point in the ultrasound image that is separated from a predetermined adjustment point in the adjustment section by a predetermined distance along the direction of the straight line connecting the adjustment point to at least one reference point. In this case, the ultrasound device 1000 can adjust the position of at least one of a plurality of measurement points by changing at least one of the position and shape of the measurement device image.

[0100] For example, the ultrasound device 1000 can adjust the position of at least one of a plurality of measurement points by adjusting the length of the measurement device image. Alternatively, for example, the ultrasound device 1000 can adjust the position of at least one of a plurality of measurement points by rotating the measurement device image. Furthermore, when the measurement device image is formed from two local images that intersect each other based on a reference point, the ultrasound device 1000 can adjust the position of at least one of a plurality of measurement points by rotating the two local images based on the reference point.

[0101] The ultrasonic device 1000 can obtain measurement values ​​for measurement items corresponding to the selected measuring device based on the locations of multiple measurement points.

[0102] When the position of at least one of a plurality of measurement points is adjusted, the ultrasonic device 1000 can obtain measurement values ​​for a measurement item corresponding to the selected measurement device based on the positions of the plurality of measurement points in the ultrasonic image.

[0103] For example, the ultrasound device 1000 can measure the distance between two measurement points on an ultrasound image based on the positions of the two measurement points on the measurement device image. The ultrasound device 1000 can generate a circle with a diameter having a straight line connecting the two measurement points as its diameter based on the positions of the measurement points, and can calculate at least one of the diameter, circumference, and area of ​​the generated circle.

[0104] In this case, in order to calculate length, area, and volume, the ultrasound device 1000 can convert the scale of the ultrasound image into the scale of the actual object.

[0105] Furthermore, the ultrasound device 1000 can construct a region of interest on an ultrasound image based on multiple measurement points and obtain measurement values ​​about the constructed region of interest. For example, the ultrasound device 1000 can construct a grid on an ultrasound image based on the positions of two measurement points and measure the blood flow velocity in the area indicated by the grid.

[0106] In operation S240, the ultrasonic device 1000 can display the acquired measurement values.

[0107] The ultrasonic device 1000 can display the obtained measurement values ​​on the measuring device image.

[0108] Additionally, the ultrasound device 1000 can receive touch input indicating the end of touch or dragging of the adjustment section. When such touch or dragging input is received, the ultrasound device 1000 can display a button image corresponding to the ultrasound image on the ultrasound image for storing measurement values.

[0109] Additionally, when receiving touch input indicating the end of a touch or drag, the ultrasound device 1000 can delete the measuring device image on the touch screen and display button images on the ultrasound image for readjusting the positions of multiple measuring points.

[0110] Figure 3 This is a view according to an embodiment for describing a method of providing a measurement device selection menu 340 via an ultrasonic device 1000.

[0111] Reference Figure 3 The ultrasonic device 1000 can display a measurement device selection menu 340.

[0112] The measuring device selection menu 340 may include icons 341 to 346 for selecting a measuring device.

[0113] Additionally, the measuring device selection menu 340 may include information indicating the shape of the area measured by the measuring device. For example, the ultrasonic device 1000 may display the word "line" indicating distance, an image indicating distance, and an icon for selecting a length measuring device.

[0114] Additionally, the measuring device selection menu 340 may include information indicating the measurement items measured by the measuring device. For example, the ultrasonic device 1000 may display the word "angle" indicating the angle measured by the measuring device, an angle image, and an icon indicating the angle measuring device.

[0115] Furthermore, when the ultrasonic device 1000 receives user input selecting one of a plurality of measuring devices, the ultrasonic device 1000 can display an image of the measuring device corresponding to the selected measuring device on the ultrasonic image. For example, when receiving user input selecting icon 341 for selecting a vernier caliper measuring device, the ultrasonic device 1000 can display an image of the vernier caliper measuring device corresponding to the vernier caliper measuring device on the ultrasonic image.

[0116] Figure 3The diagram illustrates a measurement device selection menu 340 that includes icons for a vernier caliper measuring device 341, a pliers measuring device 342, a scissors measuring device 343, a pen measuring device 345, and an angle measuring device 346. Specifically, the vernier caliper measuring device icon 341 corresponds to a vernier caliper measuring device used to measure distances between multiple measurement points; the pliers measuring device icon 342 corresponds to a pliers measuring device; the scissors measuring device icon 343 corresponds to a scissors measuring device used to measure items related to ellipses; the pen measuring device icon 345 corresponds to a pen measuring device used to measure items related to trajectories generated based on the user's touch trajectory; and the angle measuring device icon 346 corresponds to an angle measuring device. However, measuring devices can have various other shapes, and the measurement device selection menu 340 may include other measuring device icons corresponding to measuring devices of various shapes.

[0117] Figure 4 This is a flowchart of a method for providing a measuring device via an ultrasonic device 1000 according to an embodiment.

[0118] In operation S410, the ultrasonic device 1000 can receive input for selecting a vernier caliper measuring device.

[0119] In operation S420, the ultrasonic device 1000 can display an image of the vernier caliper measuring device on the ultrasonic image.

[0120] The ultrasonic device 1000 can display an image of the vernier caliper measuring device corresponding to the vernier caliper measuring device on the ultrasonic image.

[0121] An image of a vernier caliper measuring device can have the physical shape of a vernier caliper.

[0122] An image of a vernier caliper measuring device may include two measurement points indicating the positions of two points to be measured in an ultrasonic image. Additionally, the image may include an adjustment section for adjusting the position of the measurement points.

[0123] In operation S430, the ultrasonic device 1000 can receive touch input that changes the position of the adjustment portion in the image of the vernier caliper measuring device on the ultrasonic image.

[0124] When the ultrasonic device 1000 receives touch and drag input regarding the adjustment section, the ultrasonic device 1000 can move the adjustment section along the dragged area. In this case, the ultrasonic device 1000 can move the adjustment section by changing at least one of the shape and position of the adjustment section.

[0125] In operation S440, the ultrasonic device 1000 can determine the positions of two measurement points separated from the adjustment section by a predetermined distance based on the position of the changed adjustment section.

[0126] When at least one of the shape and position of the adjustment part changes, the ultrasonic device 1000 can determine the position of multiple measurement points based on the position of the adjustment part.

[0127] For example, the ultrasonic device 1000 can determine the position of the measurement point based on the position of the adjustment point. The adjustment point can be a point in the measurement device image that becomes a reference point for determining the position of the measurement point. The position of the adjustment point can be a fixed point within the adjustment section. For example, the position of the adjustment point can be the midpoint of the adjustment section. The ultrasonic device 1000 can determine the position of the adjustment point based on the position of the adjustment section.

[0128] When the ultrasonic device 1000 determines the position of the adjustment point, the ultrasonic device 1000 can determine the position of the point separated from the first adjustment point by a predetermined distance and the position of the point separated from the second adjustment point by a predetermined distance (the point separated from the first adjustment point and the point separated from the second adjustment point are points among a plurality of points on the straight line connecting the first adjustment point and the second adjustment point), and then the point separated from the determined position by a predetermined distance can be determined as the measurement point along the direction perpendicular to the straight line.

[0129] In operation S450, the ultrasonic device 1000 can adjust the position of at least one of the two measuring points in the image of the vernier caliper measuring device.

[0130] The ultrasonic device 1000 can adjust the position of at least one of the two measuring points by changing at least one of the position and shape of the vernier caliper measuring device image.

[0131] For example, the ultrasonic device 1000 can adjust the position of at least one of the two measuring points by rotating the image of the vernier caliper measuring device. Alternatively, the ultrasonic device 1000 can adjust the position of at least one of the two measuring points by extending the image of the vernier caliper measuring device.

[0132] In operation S460, the ultrasonic device 1000 can calculate the distance between two measurement points based on the determined positions of the two measurement points.

[0133] In operation S470, the ultrasonic device 1000 can display the calculated distance.

[0134] Figure 5A This is a view according to an embodiment for describing a method of providing the distance measurement function of a vernier caliper measuring device via an ultrasonic device 1000.

[0135] Reference Figure 5A When a vernier caliper measuring device is selected, the ultrasonic equipment 1000 can determine the measurement points and adjustment parts on the ultrasonic image.

[0136] For example, when receiving a selection Figure 3 When the user inputs an icon 341 indicating the vernier caliper measuring device in the measuring device selection menu 340 shown in the diagram, the ultrasound device 1000 can obtain the positions of the adjustment portion 530 and the two measurement points 511 and 513 on the ultrasound image. The adjustment portion 530 may include a first adjustment portion 531 and a second adjustment portion 533. The user can construct the measurement points 511 and 513 on the portion of the object to be measured in the ultrasound image. For example, when the object is a fetus and the measurement portion is the nuchal translucency (NT) of the fetus, the user can position the measurement points 511 and 513 at the two endpoints of the NT. In this case, the user can move the first adjustment portion 531 and the second adjustment portion 533 to position the measurement points 511 and 513 at the measurement site to be measured.

[0137] In detail, measurement points 511 and 513 can be reference points on the ultrasound image used for measurement. Additionally, the first adjustment portion 531 and the second adjustment portion 533 can be areas on the ultrasound image that receive touch input from a user to change the positions of measurement points 511 and 513. The default positions of the two measurement points 511 and 513 and the adjustment portion 530 can be predetermined according to the vernier caliper measuring device.

[0138] The vernier caliper measuring device can be used to calculate the distance between two measuring points 511 and 513. The ultrasonic device 1000 can calculate the distance between the two measuring points 511 and 513 based on the obtained positions of the two measuring points 511 and 513.

[0139] When the ultrasonic device 1000 receives touch and drag input regarding the adjustment portion 530, the ultrasonic device 1000 can move the adjustment portion 530 along the dragged area. In this case, the ultrasonic device 1000 can move the adjustment portion 530 by changing at least one of the shape and position of the adjustment portion 530.

[0140] The first adjustment portion 531 can be configured to move upward and downward. Additionally, the second adjustment portion 533 can be configured to move upward and downward or rotate based on the first adjustment point 521. Furthermore, both adjustment portions 531 and 533 can move simultaneously in parallel directions.

[0141] The other areas of the adjustment section 530, besides the first adjustment section 531 and the second adjustment section 533, can be areas used to move the two measurement points 511 and 513 and the adjustment section 530 simultaneously in parallel directions.

[0142] When the adjustment section 530 moves, the ultrasound device 1000 can determine the positions of measurement points 511 and 513 based on the position of the adjustment section 530. For example, the ultrasound device 1000 can determine the positions of adjustment points 521 and 523 based on the positions of the first adjustment section 531 and the second adjustment section 533. Adjustment points 521 and 523 can be points in the ultrasound image that become reference points for determining the positions of measurement points 511 and 513. Adjustment points 521 and 523 can be the center points of the first adjustment section 531 and the second adjustment section 533, respectively.

[0143] Furthermore, when the positions of the first adjustment portion 531 and the second adjustment portion 533 change in the ultrasound image, the ultrasound device 1000 can determine the position of point 526, which is separated from the first adjustment point 521 by a predetermined distance, and the position of point 527, which is separated from the second adjustment point 523 by a predetermined distance (points 526 and 527, which are separated from the first adjustment point 521 and the second adjustment point 523, are among a plurality of points on the straight line 525 connecting the first adjustment point 521 and the second adjustment point 523). Then, points 511 and 513, which are separated from the determined points 526 and 527 by predetermined distances along a direction perpendicular to the straight line 525, can be determined as measurement points. Therefore, measurement points 511 and 513 can be located at positions separated from the adjustment points 531 and 533 by predetermined distances, respectively.

[0144] like Figure 5A As shown, since the adjustment portion 530 is separate from the measurement points 511 and 513, when the user constructs the measurement points 511 and 513 by touching any point in the adjustment portion 530 on the touch screen, the measurement points 511 and 513 can be constructed precisely without being covered by the user's finger.

[0145] In addition, when the positions of the first adjustment portion 531 and the second adjustment portion 533 change in the ultrasound image, the ultrasound device 1000 can store the changed positions of the first adjustment portion 531 and the second adjustment portion 533, as well as the calculated positions of the measurement points 511 and 513.

[0146] Figure 5B This is a view according to an embodiment for describing a method of displaying an image 510 of a vernier caliper measuring device corresponding to a vernier caliper measuring device via an ultrasonic device 1000.

[0147] Reference Figure 5B When a vernier caliper measuring device is selected, the ultrasonic device 1000 can display the vernier caliper measuring device image 510 corresponding to the vernier caliper measuring device.

[0148] The vernier caliper measuring device image 510 may include two measuring points 511 and 513 indicating two points to be measured on the ultrasonic image. Additionally, the vernier caliper measuring device image 510 may include an adjustment portion 555 indicating an adjustment area. The adjustment portion 555 may include a first adjustment portion 557 indicating the position of a first adjustment area and a second adjustment portion 559 indicating the position of a second adjustment area.

[0149] The measuring point is set at a predetermined distance from the adjustment section 555, so the adjustment section 555, which indicates the adjustment area, can be displayed at a predetermined distance from the measuring point.

[0150] Image 510 of the vernier caliper measuring device may have the physical shape of a vernier caliper. For example, the adjustment section 555 may correspond to a region of the rod shape. In addition, the two measuring points 511 and 513 may be set at a predetermined distance from the adjustment section 555.

[0151] Additionally, when the adjustment portion 555 and the measuring points 511 and 513 are changed according to the user's touch input, the ultrasonic device 1000 can change at least one of the position and shape of the vernier caliper measuring device image 510, such that the adjustment portion 555 in the vernier caliper measuring device image 510 is located in the adjustment area, and the two measuring points 511 and 513 indicate the measuring points.

[0152] Therefore, the user can identify the measurement point constructed on the ultrasound image and the position of the adjustment section 530 from the vernier caliper measuring device image 510 displayed on the ultrasound image. Additionally, the ultrasound device 1000 can receive touch input regarding the adjustment section 530 by receiving touch input that moves the adjustment section 555 in the vernier caliper measuring device image 510. For example, the position of the first adjustment area can be moved along the area touched by the user. The ultrasound device 1000 can receive touch input from the user that moves the position of the first adjustment section 557 by displaying it on the moved first adjustment area.

[0153] Figure 5C This is a view according to an embodiment for describing a method by which a measurement point is indicated by the ultrasonic device 1000 by changing the position or shape of the vernier caliper measuring device image 510 according to user input.

[0154] Reference Figure 5CThe ultrasonic device 1000 can receive touch input that changes the position of the second adjustment portion 559. For example, the ultrasonic device 1000 can receive touch input that touches and drags the second adjustment portion 559. When receiving touch input that touches and drags the second adjustment portion 559, the ultrasonic device 1000 can adjust the positions of two measurement points 511 and 513 in the ultrasonic image by changing at least one of the position and shape of the vernier caliper measuring device image 510.

[0155] For example, the ultrasound device 1000 may receive a touch input that rotates the second adjustment portion 559 based on a first adjustment point 521 located at the center of the first adjustment portion 557. When the touch input that rotates the second adjustment portion 559 is received, the ultrasound device 1000 may determine the position of the second adjustment point 523 based on the position of the second adjustment portion 559. Once the position of the second adjustment point 523 is determined, the ultrasound device 1000 may determine the positions of two measurement points 511 and 513 based on the positions of the first adjustment point 521 and the determined second adjustment point 523.

[0156] Additionally, when a touch input is received that causes the second adjustment section 559 to rotate, the ultrasonic device 1000 can rotate the vernier caliper measuring device image 510. When the vernier caliper measuring device image 510 rotates, the points indicated by the measurement points 511 and 513 in the ultrasonic image 510 can be the points to be measured.

[0157] Additionally, for example, the ultrasonic device 1000 may receive touch input that decreases or increases the length of the vernier caliper measuring device image 510. For example, the ultrasonic device 1000 may receive touch input that moves the second adjustment portion 559 along the length direction of the vernier caliper measuring device image 510. When a touch input that moves the second adjustment portion 559 along the length direction of the vernier caliper measuring device image 510 is received, the ultrasonic device 1000 may determine the position of the second adjustment point 523 based on the position of the second adjustment portion 559. When the position of the second adjustment point 523 is determined, the ultrasonic device 1000 may determine the position of the second measurement point 513 based on the positions of the first adjustment point 521 and the determined second adjustment point 523. Furthermore, the distance between the first measurement point 511 and the second measurement point 513 may be calculated based on the positions of the first measurement point 511 and the determined second measurement point 513.

[0158] Additionally, when a touch input is received that moves the second adjustment section 559 along the length direction of the vernier caliper measuring device image 510, the length of the vernier caliper measuring device image 510 can be increased or decreased. When the length of the vernier caliper measuring device image 510 increases or decreases, the points indicated by the measurement points 511 and 513 in the vernier caliper measuring device image 510 in the ultrasonic image can be the points to be measured.

[0159] Figure 5D This is a view according to another embodiment for describing a method of constructing a measuring point by means of an ultrasonic device 1000 by changing the position of a vernier caliper measuring device image 510 according to user input.

[0160] Reference Figure 5D The ultrasonic device 1000 can receive touch input that moves the entire vernier caliper measuring device image 510.

[0161] For example, the ultrasonic device 1000 can receive user input that touches an area of ​​the entire adjustment portion other than the first and second adjustment portions. When the ultrasonic device 1000 receives user input that touches an area of ​​the entire adjustment portion other than the first and second adjustment portions, the ultrasonic device 1000 can display an image 560 on the vernier caliper measuring device image 510 indicating that the entire vernier caliper measuring device image 510 has been selected.

[0162] Additionally, when the ultrasonic device 1000 receives a touch input that moves the entire vernier caliper measuring device image 510, the ultrasonic device 1000 can move the entire vernier caliper measuring device image 510. When the entire vernier caliper measuring device image 510 moves, the point indicated by the measurement point in the vernier caliper measuring device image 510 in the ultrasonic image can be the point to be measured.

[0163] In addition, although Figure 5D The left and right sides of the vernier caliper measuring device image 510 can be changed, though not shown in the diagram. For example, when the ultrasonic device 1000 receives user input by double-clicking the vernier caliper measuring device image 510, the ultrasonic device 1000 can display the vernier caliper measuring device image with its left and right sides changed.

[0164] Figure 5E This is a view according to another embodiment for describing a method by which a measurement point is indicated by an ultrasonic device 1000 by changing the position or shape of a vernier caliper measuring device image 510 according to user input.

[0165] Reference Figure 5E The ultrasonic device 1000 can receive touch input that changes the position of the first adjustment portion 557. When receiving input that changes the position of the first adjustment portion 557, the ultrasonic device 1000 can adjust the position of the first measurement point 511 in the ultrasonic image by changing at least one of the position and shape of the vernier caliper measuring device image 510.

[0166] Additionally, the ultrasonic device 1000 can receive touch input that increases or decreases the length of the vernier caliper measuring device image 510. For example, the ultrasonic device 1000 can receive touch input that moves the first adjustment portion 557 along the length direction of the vernier caliper measuring device image 510. When receiving touch input that moves the first adjustment portion 557 along the length direction of the vernier caliper measuring device image 510, the ultrasonic device 1000 can determine the position of the first adjustment point 521 based on the position of the first adjustment portion 557. When the position of the first adjustment point 521 is determined, the ultrasonic device 1000 can determine the position of the first measurement point 511 based on the changed first adjustment point 521 and second adjustment point 523. Furthermore, the distance between the first measurement point 511 and the second measurement point 513 can be calculated based on the determined positions of the first measurement point 511 and the second measurement point 513.

[0167] Furthermore, when a touch input is received that moves the first adjustment portion 557 along the length direction of the vernier caliper measuring device image 510, the ultrasonic device 1000 can change the position of the first adjustment portion 557 by increasing or decreasing the length of the vernier caliper measuring device image 510. When the length of the vernier caliper measuring device image 510 increases or decreases, the points indicated by the measurement points 511 and 513 in the vernier caliper measuring device image 510 in the ultrasonic image can be the points to be measured.

[0168] Figure 6 This is a view according to an embodiment for describing a method of storing and calculating measurement values ​​by an ultrasonic device 1000.

[0169] Reference Figure 6 The ultrasound device 1000 can display button images on the ultrasound image for storing calculated measurement values.

[0170] For example, when the ultrasound device 1000 receives user input that ends the touch and drag input regarding the adjustment portion in the measurement device image, the ultrasound device 1000 may display a button image for storing the calculated measurement value.

[0171] When the ultrasonic device 1000 receives input by touching a button image used to store calculated measurement values, it can store the calculated measurement values ​​based on the recognition information of the ultrasonic image.

[0172] In addition, when the user selects the measurement site and measurement item 620 before selecting the measuring device, the ultrasonic device 1000 can display or store the calculated measurement value corresponding to the pre-selected measurement site and measurement item as the measurement value when it receives user input by touching the icon for storing measurement values.

[0173] In addition, the ultrasonic device 1000 can not only store measurement values, but also the positions of measurement points and adjustment areas.

[0174] Figure 7A This is a view according to an embodiment for describing a method of providing the distance measurement function of a clamp measuring device via an ultrasonic device 1000.

[0175] Reference Figure 7A The ultrasonic device 1000 can display the image 710 of the forceps measuring device on the ultrasonic image.

[0176] When the ultrasonic device 1000 receives user input of the clamp measuring device icon 342 in the selection menu 340 for selecting a measuring device, the ultrasonic device 1000 can display the clamp measuring device image 710 on the ultrasonic image.

[0177] The pliers measuring device image 710 may have the physical shape of pliers. Alternatively, the pliers measuring device image 710 may be formed from two images.

[0178] The forceps measuring device image 710 may include two measuring points 711 and 713 indicating two points to be measured in the ultrasound image. Additionally, the forceps measuring device 710 may include two adjusting portions 761 and 763 for adjusting the positions of the two measuring points 711 and 713.

[0179] The positions of measuring points 711 and 713, as well as adjusting portions 761 and 763, can be predetermined in the pliers measuring device image 710. For example, measuring points 711 and 713 in the pliers measuring device image 710 can be the ends of the pincer portions 751 and 753 of the pliers. Additionally, adjusting portions 761 and 763 in the pliers measuring device image 710 can be the handle portion of the pliers.

[0180] The ultrasonic device 1000 can display the forceps measuring device image 710 such that two measurement points 711 and 713 in the forceps measuring device image 710 indicate two points to be measured in the ultrasonic image, and that two adjustment portions 761 and 763 in the forceps measuring device image 710 are located in adjustment areas for receiving user touch input. Therefore, the ultrasonic device 1000 can receive user touch input through the adjustment portions 761 and 763.

[0181] When the ultrasound device 1000 receives a touch input from a user to move the adjustment parts 761 and 763 on the ultrasound image, it can determine the positions of two measurement points on the ultrasound image based on the changed positions of the adjustment parts 761 and 763. For example, the ultrasound device 1000 can determine two measurement points as points separated from the adjustment parts 761 and 763 by a predetermined distance. In this case, the ultrasound device 1000 can determine two measurement points such that the straight line connecting the two measurement points is parallel to the adjustment parts 761 and 763.

[0182] Additionally, when receiving touch input from a user that moves adjustment portions 761 and 763 on an ultrasound image, the ultrasound device 1000 may change at least one of the position and shape of the forceps measuring device image 710, such that measurement points 711 and 713 in the forceps measuring device image 710 indicate the points to be measured.

[0183] For example, when the ultrasonic device 1000 receives a touch input that rotates the adjustment portions 761 and 763 in the same direction, the ultrasonic device 1000 can rotate the forceps measuring device image 710 based on a predetermined point in the forceps measuring device image 710. Additionally, when a touch input that moves the adjustment portions 761 and 763 is received, the ultrasonic device 1000 can move the entire forceps measuring device image 710 to another position in the ultrasonic image. Furthermore, when a touch input that selects the first adjustment portion 761 and the second adjustment portion 763 in the forceps measuring device image 710 and drags them in opposite directions or in a direction that brings the first adjustment portion 761 and the second adjustment portion 763 closer to each other is received, the ultrasonic device 1000 can perform parallel movement of the two images corresponding to the two forceps respectively in opposite directions or in a direction that brings the two images closer to each other. Additionally, the ultrasonic device 1000 can adjust the length of the forceps measuring device image 710 based on a predetermined point in the forceps measuring device image 710.

[0184] Figure 7B This is a view according to another embodiment for describing a method of providing a clamp measuring device via an ultrasonic device 1000.

[0185] Reference Figure 7B The ultrasonic device 1000 can display the measurement values ​​obtained through the image 710 of the clamp measuring device.

[0186] When the ultrasound device 1000 receives touch input from a user that moves adjustment portions 761 and 763 on the ultrasound image, the ultrasound device 1000 can determine the positions of measurement points 711 and 713 and calculate the distance between measurement points 711 and 713 based on the determined positions. Furthermore, the ultrasound device 1000 can display the calculated distance information 770 on the ultrasound image.

[0187] In addition, the ultrasound device 1000 can display an image 760 on the ultrasound image indicating the location and extent of the measurement area.

[0188] Furthermore, the ultrasound device 1000 can construct a measurement area as a region of interest and display information of interest about the constructed region of interest. For example, the ultrasound device 1000 can construct the measurement area as a sample volume. Additionally, the ultrasound device 1000 can display information about blood flow at the site indicated by the constructed sample volume as a spectrum. Therefore, the user can adjust the length of the sample volume via the forceps measuring device image 710.

[0189] Figure 8 This is a flowchart of a method for providing the measurement function of a scissor measuring device via an ultrasonic device 1000 according to an embodiment.

[0190] In operation S810, the ultrasonic device 1000 can receive user input to select the scissor measuring device.

[0191] In operation S820, the ultrasonic device 1000 can display an image of the scissor measuring device on the ultrasonic image.

[0192] The ultrasonic device 1000 can display an image of the scissor measuring device corresponding to the scissor measuring device on the ultrasonic image.

[0193] An image of a scissors measuring device can have the physical shape of scissors.

[0194] An image of a scissors measuring device may include two measurement points, which indicate two points in the ultrasound image to be measured. The measurement points can be points on the ultrasound image that become reference points for measurement. Multiple measurement points in an image of a scissors measuring device with a solid scissors shape can be the endpoints of the two edges of the scissors.

[0195] Additionally, the image of the scissors measuring device may include an adjustment section indicating the adjustment area. Furthermore, the adjustment area may be an area on the ultrasound image for receiving touch input from the user to change the position of the measurement point. Also, in an image of a scissors measuring device with a scissors shape, the adjustment section may be the handle portion of the scissors.

[0196] Furthermore, the adjustment section and the measurement point can be set to be separate from each other in the measurement device image. For example, the adjustment section can be set to not coincide with the measurement point in the measurement device image. Alternatively, for example, in the measurement device image, the adjustment section can be located in an area separated from the measurement point by a predetermined distance.

[0197] In operation S830, the ultrasonic device 1000 can receive touch input on the ultrasonic image to change the position of the adjustment portion of the scissor measuring device image.

[0198] When receiving touch and drag input regarding the adjustment section, the ultrasonic device 1000 can move the adjustment section along the dragged area. In this case, the ultrasonic device 1000 can move the adjustment section by changing at least one of the shape and position of the adjustment section.

[0199] In operation S840, the ultrasonic device 1000 can determine the positions of two measurement points separated from the adjustment section by a predetermined distance based on the position of the changed adjustment section.

[0200] When at least one of the shape and position of the adjustment part changes, the ultrasonic device 1000 can determine the position of multiple measurement points based on the position of the adjustment part.

[0201] For example, the ultrasonic device 1000 can determine the position of the adjustment point based on the position of the adjustment section. The adjustment point can be a reference point in the measurement device image used to determine the position of the measurement point. The adjustment point can be a fixed point within the adjustment section.

[0202] When the position of the adjustment point is determined, the ultrasonic device 1000 can determine a point separated from the adjustment point by a predetermined distance as a measurement point along the direction of the straight line connecting the adjustment point and at least one reference point determined on the ultrasonic image.

[0203] The ultrasonic device 1000 can adjust the position of the adjustment portion and the two measurement points by changing at least one of the position and shape of the scissor measuring device image. For example, when the area indicating the scissor handle is moved, the ultrasonic device 1000 can change the scissor measuring device image to a shape in which the two edges of the scissors are closed or open, such that the ends of the two edges of the scissors indicate the points to be measured in the ultrasonic image.

[0204] In operation S850, the ultrasonic device 1000 can determine a circle with the line segment connecting the two measurement points as its diameter based on the positions of the two determined measurement points.

[0205] In operation S860, the ultrasonic device 1000 can calculate and display the measured values ​​about the circle.

[0206] The ultrasonic device 1000 can calculate at least one of the diameter, circumference, and area of ​​a circle.

[0207] Figure 9A This is a view according to an embodiment for describing a method of providing the measurement function of a scissor measuring device via an ultrasonic device 1000.

[0208] Reference Figure 9A The ultrasonic device 1000 can display the image of the scissor measuring device on the ultrasonic image.

[0209] When the ultrasonic device 1000 receives user input indicating the selection of the scissor measuring device icon 343, the ultrasonic device 1000 can display an image of the scissor measuring device corresponding to the scissor measuring device on the ultrasonic image.

[0210] Figure 9B This is a view according to an embodiment for describing a method of obtaining a measurement value of a circle with respect to a scissor measuring device via an ultrasonic device 1000.

[0211] When the ultrasonic device 1000 receives user input selecting the scissor measuring device, the ultrasonic device 1000 can obtain the positions of two measuring points 911 and 913 corresponding to the scissor measuring device and two adjustment areas 961 and 963 on the ultrasonic image. The measuring points can be reference points on the ultrasonic image used for measurement. Additionally, the adjustment areas can be areas on the ultrasonic image that receive touch input from the user to change the position of the measuring points. The default positions of the two measuring points 911 and 913 and the two adjustment areas 961 and 963 can be predetermined according to the scissor measuring device.

[0212] The scissor measuring device can be used to measure the diameter, perimeter, and area of ​​a circular region 953 having a straight line 951 connecting two measuring points 911 and 913 as its diameter. The ultrasonic device 1000 can determine the circular region 953 based on the obtained positions of the two measuring points 911 and 913. Furthermore, the ultrasonic device 1000 can calculate the diameter, perimeter, and area of ​​the circular region 953 based on the obtained positions of the measuring points 911 and 913.

[0213] When receiving touch and drag input regarding adjustment areas 961 and 963, the ultrasonic device 1000 can move adjustment areas 961 and 963 along the drag area. In this case, the ultrasonic device 1000 can move adjustment areas 961 and 963 by changing their positions.

[0214] In addition, when the position of the adjustment area is changed by user input, the ultrasound device 1000 can determine the position of the measurement points 911 and 913 based on the position of the adjustment areas 961 and 963.

[0215] For example, the ultrasound device 1000 can determine the positions of two adjustment points 921 and 923 based on the positions of a first adjustment region 961 and a second adjustment region 963. The positions of the two adjustment points 921 and 923 can be predetermined within the adjustment regions 961 and 963. The two adjustment points 921 and 923 can include a first adjustment point 921 in the first adjustment region 961 and a second adjustment point 923 in the second adjustment region 963.

[0216] The ultrasonic device 1000 can determine the intersection point 925 of the straight lines connecting the two adjustment points 921 and 923 to two pre-stored measurement points 911 and 913, respectively. The intersection point 925 can be a reference point for the movement of the first adjustment region 961 and the second adjustment region 963.

[0217] When the ultrasound device 1000 receives user input that it rotates the first adjustment region 961 or the second adjustment region 963 based on the intersection point 925, the ultrasound device 1000 can rotate the first adjustment region 961 and the second adjustment region 963 based on the intersection point 925. When the second adjustment point 923 rotates based on the intersection point 925, the ultrasound device 1000 can determine a point separated from the second adjustment point 923 by a predetermined distance along the direction of the straight line connecting the second adjustment point 923 and the intersection point 925, as a first measurement point 911, based on the changed position of the second adjustment point 923. Furthermore, when the first adjustment point 921 rotates based on the intersection point 925, the ultrasound device 1000 can determine a point separated from the first adjustment point 921 by a predetermined distance along the direction of the straight line connecting the first adjustment point 921 and the intersection point 925, as a second measurement point 913, based on the changed position of the first adjustment point 921.

[0218] In addition, when the positions of the first adjustment region 961 and the second adjustment region 963 in the ultrasound image change, the ultrasound device 1000 can store the changed positions of the first adjustment region 961 and the second adjustment region 963, as well as the determined positions of the measurement points 911 and 913.

[0219] The first adjustment region 961 and the second adjustment region 963 can be configured to be rotatable based on the intersection point 925. Furthermore, touch input regarding the first adjustment region 961 and the second adjustment region 963 can be received simultaneously. Therefore, the ultrasonic device 1000 can simultaneously change two measurement points 911 and 913 by receiving two touch inputs.

[0220] In addition, when the ultrasound device 1000 receives a long touch input regarding the first adjustment region 961 and the second adjustment region 963, as well as a touch input that moves the first adjustment region 961 and the second adjustment region 963, the ultrasound device 1000 can move the first adjustment region 961, the second adjustment region 963 and the intersection point 925 simultaneously in a parallel direction.

[0221] In addition, when the ultrasound device 1000 receives a long touch input regarding the first adjustment region 961 and the second adjustment region 963, as well as a touch input that rotates the first adjustment region 961 and the second adjustment region 963, the ultrasound device 1000 can simultaneously rotate the first adjustment region 961, the second adjustment region 963, and the intersection point 925.

[0222] Furthermore, when the ultrasonic device 1000 receives touch input regarding the intersection point 925 and touch input that moves the intersection point 925, the ultrasonic device 1000 can move the positions of the measurement points 911 and 913 based on the adjustment points 921 and 923 and the moved intersection point 925. For example, when receiving touch input that moves the intersection point 925 closer to the adjustment points 921 and 923, the ultrasonic device 1000 can determine the positions of the measurement points 911 and 913 based on the adjustment points 921 and 923 and the moved intersection point 925. In this case, the measurement points 911 and 913 can move away from each other. Conversely, when receiving touch input that moves the intersection point 925 away from the adjustment points 921 and 923, the ultrasonic device 1000 can determine the positions of the measurement points 911 and 913 based on the adjustment points 921 and 923 and the moved intersection point 925. In this case, the measurement points 911 and 913 can move closer to each other.

[0223] Figure 9C This is a view according to an embodiment for describing a method of displaying a measuring device image 910 corresponding to a scissor measuring device via an ultrasonic device 1000.

[0224] Reference Figure 9C When the scissor measuring device is selected, the ultrasonic device 1000 can display the measuring device image 910 corresponding to the scissor measuring device.

[0225] The measuring device image 910 corresponding to the scissor measuring device may include two measuring points 911 and 913 indicating the points to be measured in the ultrasound image. Additionally, the measuring device image 910 corresponding to the scissor measuring device may include two adjustment portions 991 and 993 indicating the adjustment area. Furthermore, the measuring device image 910 may display an image 953 indicating a circle with a diameter having a straight line connecting the two measuring points 911 and 913.

[0226] The measuring device image 910 corresponding to the scissor measuring device may have the physical shape of scissors. Furthermore, the positions of the two measuring points 911 and 913 and the two adjusting portions 991 and 993 may be predetermined in the scissor measuring device image 910. For example, the two measuring points 911 and 913 may be the ends of the two edges of the scissors in the scissor measuring device image 910. Additionally, the two adjusting portions 991 and 993 may be the handle portion of the scissors in the scissor measuring device image 910.

[0227] The ultrasonic device 1000 can display the scissor measuring device image 910 such that two measurement points 911 and 913 in the scissor measuring device image 910 indicate two points to be measured in the ultrasonic image, and the intersection of the two edges of the scissors is located at... Figure 9BAt the intersection point 925. Therefore, the measuring device image 910 can have two local images based on the shape of the intersection point intersecting each other.

[0228] Furthermore, the ultrasound device 1000 can receive touch input regarding the adjustment area by receiving touch input that moves the adjustment portions 991 and 993 in the measurement device image 910. For example, the ultrasound device 1000 can move the position of the first adjustment area along the touch area. Additionally, the ultrasound device 1000 can receive touch input from the user that moves the position of the first adjustment portion 991 by displaying it at the moved position of the first adjustment area. Therefore, the user can identify the positions of the adjustment areas and measurement points constructed on the ultrasound image from the measurement device image 910 displayed on the ultrasound image.

[0229] Figure 9D This is a view according to an embodiment for describing a method of indicating measurement points by changing the position or shape of a measuring device image 910 via an ultrasonic device 1000 according to user input.

[0230] Reference Figure 9D The ultrasound device 1000 can receive touch input that changes the position of adjustment portions 991 and 993. When receiving touch input that changes the position of adjustment portions 991 and 993, the ultrasound device 1000 can adjust the position of two measurement points 911 and 913 in the ultrasound image by changing at least one of the position and shape of the measurement device image 910.

[0231] For example, when the ultrasound device 1000 receives user input that rotates the adjustment parts 991 and 993 so that the adjustment parts 991 and 993 move away from each other in opposite directions or move closer to each other in the same direction, the ultrasound device 1000 can determine the positions of the two measurement points 911 and 913 based on the changed positions of the adjustment parts 991 and 993 and the position of the intersection point 925.

[0232] Furthermore, when receiving user input that rotates adjustment portions 991 and 993 to move them away from each other in opposite directions or towards each other in the same direction, the ultrasound device 1000 can rotate the two local images based on the intersection point 925. For example, the ultrasound device 1000 can rotate the two edges of the scissors in the scissors measuring device image 910 based on the intersection point 925. In this case, the speed and angle of rotation can be determined based on the speed and distance at which the adjustment portions 991 and 993 move away from each other in opposite directions. When the two local images are rotated, the points indicated by the measurement points 911 and 913 in the measuring device image 910 in the ultrasound image can be the points to be measured.

[0233] Furthermore, once the positions of measurement points 911 and 913 are determined, the ultrasonic device 1000 can determine a circle having a diameter formed by the straight line formed by the two measurement points 911 and 913. Additionally, the ultrasonic device 1000 can display an image 953 indicating the circle at the determined location. Furthermore, the ultrasonic device 1000 can calculate at least one of the diameter, circumference, and area of ​​the determined circle.

[0234] Additionally, when the ultrasound device 1000 receives two touch inputs regarding the adjustment sections 991 and 993, the ultrasound device 1000 can simultaneously rotate the two local images based on the intersection point 925.

[0235] Additionally, when the ultrasonic device 1000 receives a long touch input regarding the first adjustment section 991 and the second adjustment section 993, as well as a touch input that moves the first adjustment section 991 and the second adjustment section 993, the ultrasonic device 1000 can move the entire scissor measuring device image 910.

[0236] Additionally, when the ultrasonic device 1000 receives a long touch input regarding the first adjustment section 991 and the second adjustment section 993, as well as a touch input that rotates the first adjustment section 991 and the second adjustment section 993, the ultrasonic device 1000 can rotate the entire scissor measuring device image 910.

[0237] Figure 10A This is a view according to another embodiment of a method for describing a measurement function that provides a direct change mode via an ultrasonic device 1000.

[0238] Reference Figure 10A The ultrasonic device 1000 can display a button image 1030 for entering a direct change mode, in which the constructed measurement area can be changed without using the measurement device image.

[0239] When the user finishes touch input regarding the measurement device image, the ultrasound device 1000 may display a button image 1030 for entering the direct change mode. In this case, the ultrasound device 1000 may also display a button image for storing measurement values. Additionally, when receiving user input by double-clicking an area of ​​the ultrasound image that is not displaying the measurement device image, the ultrasound device 1000 may display a button image 1030 for entering the direct change mode.

[0240] When the ultrasonic device 1000 receives user input by touching the button image 1030 for entering the direct change mode, it can delete the measuring device image and display an image 1010 indicating the constructed measuring area.

[0241] Additionally, when the ultrasound device 1000 enters the direct change mode, it can display an image indicating that it has entered the direct change mode. For example, the ultrasound device 1000 can change the size or color of the image 1010 indicating the measurement area. Furthermore, the ultrasound device 1000 can display an image of the handle of the adjustment section indicating the measurement area in image 1010 on the adjustment section.

[0242] Figure 10B This is a view according to an embodiment for describing a method of changing the constructed measurement area by means of an ultrasonic device 1000 in a direct change mode.

[0243] Reference Figure 10B When the ultrasonic device 1000 receives touch input regarding an image 1010 indicating a measurement area, the ultrasonic device 1000 can change the constructed measurement area. Furthermore, the ultrasonic device 1000 can calculate the diameter, circumference, and area of ​​a circle based on the changed measurement area.

[0244] In addition, when the ultrasound device 1000 receives user input that selects a portion of the indicated measurement area in the image 1010 of the ultrasound image and moves the position of the selected portion of the image 1010, the ultrasound device 1000 can change the position or shape of the indicated measurement area of ​​the image 1010 based on the position of the moved portion.

[0245] In addition, the ultrasonic device 1000 can store the changed positions of the measurement area and the measurement points.

[0246] Additionally, when receiving user input to select the scissor measuring device, the ultrasonic device 1000 can display an image of the measuring device based on the stored locations of the measuring points.

[0247] Figure 11A This is a view according to an embodiment for describing a method of providing the measurement function of a pen measuring device via an ultrasonic device 1000.

[0248] Reference Figure 11A When the pen measuring device icon 345 is selected, the ultrasound device 1000 can display a pen measuring device image 1110 corresponding to the pen measuring device. The pen measuring device image 1110 may include a measurement point 1121 in the ultrasound image that indicates a trajectory point 1111, and an adjustment portion 1123 that receives touch input from the user. The adjustment portion 1123 may be displayed in an adjustment area in the ultrasound image that determines the position of the trajectory point 1111. In addition, the ultrasound device 1000 may determine a point separated from the adjustment area by a predetermined distance as the trajectory point 1111.

[0249] The pen measuring device image 110, corresponding to the pen measuring device, may have the physical shape of a pen. Furthermore, the positions of the adjustment portion 1123 and the measuring point 1121 in the pen measuring device image 1110 may be predetermined. For example, the adjustment portion 1123 may be the handle portion in the pen measuring device image 1110. Additionally, the measuring point 1121 may be the pen tip portion in the pen measuring device image 1110.

[0250] Figure 11B This is a view according to another embodiment of a method for describing the trajectory function of a pen measuring device image 1110 provided by an ultrasonic device 1000.

[0251] Reference Figure 11B When a touch input is received that moves the image 1110 of the pen measuring device, the ultrasonic device 1000 can determine the line segment connecting the trajectory point 1111.

[0252] When a touch input is received that moves the position of the adjustment portion 1123 of the pen measuring device image 1110 in the ultrasound image, the ultrasound device 1000 can move the pen measuring device image along the area touched by the user. Additionally, the ultrasound device 1000 can determine the position of the trajectory point 1111 based on the position of the adjustment portion 1123.

[0253] Additionally, when a touch input is received that moves the position of the adjustment portion 1123 in the ultrasound image, the ultrasound device 1000 can display a line image 1120 on the ultrasound image indicating the determined trajectory point 1111.

[0254] Additionally, when a touch input is received that moves the position of the adjustment portion 1123 in the ultrasound image, the ultrasound device 1000 can update the line 1120 connecting the trajectory point 1111.

[0255] When the line 1120 connecting trajectory point 1111 is updated, the ultrasonic device 1000 can calculate the length of the updated line 1120. Additionally, the ultrasonic device 1000 can calculate the displacement between the trajectory start point and the trajectory end point. Furthermore, when the line 1120 connecting trajectory point 1111 is a lopped curve, the ultrasonic device 1000 can calculate the minor axis, major axis, perimeter, and area of ​​the lopped curve.

[0256] Although Figure 11BAlthough not shown, the ultrasonic device 1000 can adjust the size of the pen measuring device image 1110. For example, when the ultrasonic device receives a long touch input regarding the adjustment section 1123 and a touch input dragging the adjustment section 1123 along the length direction of the pen measuring device image or in the opposite direction, the ultrasonic device 1000 can adjust the length of the pen measuring device image 1110. For example, when receiving a touch input that extends the pen measuring device image 1110 along its length direction, the ultrasonic device 1000 can increase the size of the pen measuring device image 1110 by extending it along the dragging area. Additionally, for example, when receiving a touch input that shortens the pen measuring device image 1110 along its length direction, the ultrasonic device 1000 can shorten the pen measuring device image 1110 along the dragging area. For example, the ultrasonic device 1000 can change the pen measuring device image 1110 from 10cm to 5cm.

[0257] Figure 11C This is a view according to another embodiment for describing a method of providing trajectory functionality via an ultrasonic device 1000.

[0258] Reference Figure 11C The ultrasound device 1000 can display a button image 1130 for updating the structure of the line 1120.

[0259] For example, when touch input regarding the pen measuring device image 1110 ends, the ultrasonic device 1000 may delete the pen measuring device image 1110 and display a button image 1130 for updating the configuration line 1120. In this case, the ultrasonic device 1000 may not delete the image 1120 indicating the configuration line 1120.

[0260] Additionally, when the touch input regarding the pen measuring device image 1110 ends, the ultrasonic device 1000 may display a button image 1140 for storing information about the constructed line 1120. The information about the constructed line 1120 may include the positions of the trajectory points 1111 that form the constructed line 1120 and the measurement values ​​of the line 1120.

[0261] When a touch input is received that selects a button image 1130 for updating the constructed line 1120, the ultrasound device 1000 can display a pen measuring device image 1110 on the ultrasound image, such that the measurement points of the pen measuring device image 1110 indicate the start or end point of the constructed line 1120. Additionally, when a touch input is received that moves the position of an adjustment portion in the ultrasound image, the ultrasound device 1000 can update the constructed line 1120.

[0262] Figure 12A This is a view according to an embodiment for describing a method of providing angle measurement functionality via an ultrasonic device 1000.

[0263] Reference Figure 12A When an angle measuring device is selected, the ultrasonic device 1000 can display an angle measuring device image 1210 corresponding to the angle measuring device. The angle measuring device image 1210 may include two straight lines 1221 and 1223 that generate the angle. Additionally, the angle measuring device image 1210 may include three adjustment portions 1211, 1213, and 1215. The three adjustment portions 1211, 1213, and 1215 may be located at the vertex of the angle formed by the two straight lines 1221 and 1223, and at the endpoints of the two straight lines 1221 and 1223.

[0264] The ultrasonic device 1000 can measure the angle between two straight lines 1221 and 1223. The ultrasonic device 1000 can measure the angle between the two straight lines 1221 and 1223 based on the positions of three adjustment parts 1211, 1213, and 1215. For example, the ultrasonic device 1000 can measure the angle between the two straight lines 1221 and 1223 based on the position of the midpoint of the three adjustment parts 1211, 1213, and 1215.

[0268] Furthermore, when a touch input is received regarding the first adjustment portion 1211 on the first straight line 1221, the ultrasonic device 1000 can rotate the first straight line 1221 based on its vertex. Additionally, when a touch input is received regarding the second adjustment portion 1213 on the second straight line 1223, the ultrasonic device 1000 can rotate the second straight line 1223 based on its vertex.

[0269] When the position and shape of the measuring device image 1210 change, the ultrasonic device 1000 can measure the angle formed by the two straight lines 1221 and 1223 based on the positions of the three adjustment parts 1211, 1213 and 1215 in the angle measuring device image 1210.

[0271] Reference Figure 13 When an angle measuring device is selected, the ultrasonic device 1000 can display an angle measuring device image 1310 corresponding to the angle measuring device.

[0272] The angle measuring device image 1310 may include two straight lines 1321 and 1323 that generate the angle. Additionally, the angle measuring device image 1310 may include four adjustment portions 1311, 1313, 1331, and 1333. The four adjustment portions 1311, 1313, 1331, and 1333 may be located at the endpoints of the two straight lines 1321 and 1323, and at the midpoint of the two straight lines 1321 and 1323.

[0273] The ultrasonic device 1000 can measure the angle formed by two straight lines 1321 and 1323. For example, the ultrasonic device 1000 can determine the intersection point where the two straight lines 1321 and 1323 intersect each other when they extend, based on the positions of the endpoints of the two straight lines 1321 and 1323. Once the intersection point is determined, the ultrasonic device 1000 can calculate the angle formed by the two straight lines 1321 and 1323 at the intersection point.

[0274] When the ultrasonic device 1000 receives a touch input regarding the adjustment portion 1331 located at the midpoint of the first straight line 1321, the ultrasonic device 1000 can move the first straight line 1321 in a parallel direction. Furthermore, when the ultrasonic device 1000 receives a touch input regarding the adjustment portion 1333 located at the midpoint of the second straight line 1323, the ultrasonic device 1000 can move the entire second straight line 1323 in a parallel direction.

[0275] Furthermore, when the ultrasound device 1000 receives touch input regarding the adjustment portion 1311 located at the endpoint of the first straight line 1321, the ultrasound device 1000 can rotate the first straight line 1321 based on the adjustment portion 1331 located at the midpoint of the first straight line 1321. Additionally, when the ultrasound device 1000 receives touch input regarding the adjustment portion 1313 located at the endpoint of the second straight line 1323, the ultrasound device 1000 can rotate the second straight line 1323 based on the adjustment portion 1333 located at the middle position of the second straight line 1323.

[0276] When the positions of the first straight line 1321 and the second straight line 1323 change, the ultrasonic device 1000 can determine the intersection point of the first straight line 1321 and the second straight line 1323, or the intersection point of the extensions of the first straight line 1321 and the second straight line 1323. Furthermore, the ultrasonic device 1000 can calculate the angle formed by the first straight line 1321 and the second straight line 1323 based on the determined intersection point.

[0278] Reference Figure 14 The ultrasound device 1000 may include a display unit 1100, a user input unit 1200, and a control unit 1300. However, not all of the components shown are necessary. The ultrasound device 1000 may be implemented with more or fewer components than those shown.

[0279] The components shown below will be described.

[0280] The display unit 1100 can display ultrasound images and images of the user interface.

[0281] The display unit 1100 can display a measuring device image on an ultrasound image. The measuring device image includes multiple measuring points indicating points to be measured in the ultrasound image and an adjustment section for adjusting the multiple measuring points. The measuring points can be set to be separate from the adjustment section.

[0282] When the adjustment portion of the measuring device image and the position of the measuring point change in the ultrasonic image, the display unit 1100 can update the measuring device image on the screen.

[0283] The user input unit 1200 can receive touch input to change the position of the adjustment part.

[0284] In addition, the user input unit 1200 can receive touch and drag input regarding the adjustment section.

Additionally, the control unit 1300 can adjust the position of at least one of the plurality of measuring points by changing at least one of the position and shape of the measuring device image.

[0286] For example, when a touch input is received to change the position of the adjustment section, the control unit 1300 can adjust the position of at least one of the multiple measurement points by adjusting the length of the measurement device image.

[0287] For example, when a touch input is received to change the position of the adjustment section, the control unit 1300 can adjust the position of at least one of the multiple measurement points by rotating the measurement device image.

[0288] For example, when the measuring device image includes two partial images that intersect each other based on a reference point, the control unit 1300 can adjust the position of at least one of a plurality of measuring points by rotating the two partial images based on the reference point.

[0289] In addition, the control unit 1300 can generate a circle based on the positions of multiple measurement points and can calculate at least one of the diameter, circumference and area of ​​the generated circle.

[0290] In addition, the display unit 1100 can display the obtained measurement values ​​on the image of the measuring device.

[0291] Additionally, the display unit 1100 can display the measuring device image semi-transparently, ensuring that the area where the ultrasound image overlaps with the measuring device image is not covered by the measuring device image. The display unit 1100 can also display button images on the ultrasound image for storing measurement values ​​and corresponding to the ultrasound image.

[0292] Additionally, the display unit 1100 can delete the measuring device image and display button images on the ultrasound image for readjusting the positions of multiple measuring points.

The probe 20 includes a plurality of transducers, and the plurality of transducers oscillate in response to an electrical signal and generate acoustic energy (i.e., ultrasonic waves). Furthermore, the probe 20 can be wired or wirelessly connected to the body of the ultrasonic device 1000, which, according to an embodiment, may include a plurality of probes 20.

[0297] Transmitter 110 supplies a drive signal to probe 20. Transmitter 110 includes a pulse generator 112, a transmission delay unit 114, and a pulser 116.
