Description

Technical Field

[0001] The present invention relates to the field of ultrasonic imaging, and in particular to a multi-modal combined ultrasonic measurement method and an ultrasonic imaging system. Background Art

[0002] Medical ultrasonic imaging diagnostic equipment uses the propagation of ultrasonic waves in the human body to obtain ultrasonic characteristic information of human tissue and organ structure. Specifically, the ultrasonic imaging system uses an ultrasonic probe to transmit ultrasonic waves to human tissue and receives echoes reflected by human tissue structure to form ultrasonic echo signals. The ultrasonic imaging system forms various imaging modes (modalities) based on the ultrasonic echo signals.

[0003] Currently, in many clinical scenarios, single-modality images and quantitative parameter evaluations are limited in disease diagnosis and evaluation. In some scenarios, multi-modality (modality) combined imaging can be enabled. However, currently, not only are there only a few manufacturers of ultrasound equipment that can support multi-modality combined imaging, but the measurement of related parameters in multi-modality combined imaging is also unsatisfactory.

[0076] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0077] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0078] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0079] In some scenarios, single modality images and quantitative parameter evaluations are very limited in disease diagnosis and evaluation. For example, due to the influence of acute inflammation, the use of shear wave elasticity alone to evaluate the degree of hepatitis B liver fibrosis is limited; for another example, B-mode ultrasound has low sensitivity and cannot detect early fatty liver, and lacks quantitative evaluation tools; for another example, non-alcoholic fatty liver disease has complex and diverse manifestations, including steatosis, inflammation, ballooning and fibrosis, and the parameters measured by a single modality image alone cannot be accurately evaluated.

[0080] However, currently only a few manufacturers of ultrasound equipment can support multi-modal joint imaging, and the measurement of related parameters in multi-modal joint imaging is not satisfactory. For example, there are few quantitative parameters supported, and the parameter measurement of each modality image is also relatively fragmented in operation, making the operation more cumbersome. This not only limits doctors' comprehensive evaluation of lesions, but also seriously reduces work efficiency.

[0081] First, a description is given of the ultrasound imaging system.

[0082] Please refer to Figure 1 In some embodiments, an ultrasound imaging system is provided, which includes an ultrasound probe 10, a transmission and reception control circuit 20 and a processor 40; in some embodiments, an echo processing module 30 and / or a display component 50 may also be included. Each component is described below.

[0083] The ultrasonic probe 10 is used to transmit ultrasonic waves to the region of interest, and to receive corresponding ultrasonic echo signals to obtain ultrasonic data, such as two-dimensional ultrasonic data or three-dimensional ultrasonic data. In some specific embodiments, the ultrasonic probe 10 includes a plurality of array elements, which are used to realize the mutual conversion between electrical pulse signals and ultrasonic waves, so as to realize the transmission of ultrasonic waves to the region of interest and the reception of corresponding ultrasonic echo signals. The array element can transmit ultrasonic waves according to the excitation electrical signal, or convert the received ultrasonic waves into electrical signals. Therefore, each array element can be used to transmit ultrasonic waves to the biological tissue of the region of interest, and can also be used to receive ultrasonic echoes returned by the tissue. When performing ultrasonic detection, which array elements are used to transmit ultrasonic waves and which array elements are used to receive ultrasonic waves can be controlled by the transmission sequence and the reception sequence, or the array elements can be controlled to transmit ultrasonic waves or receive ultrasonic echoes in time slots. All array elements participating in ultrasonic emission can be simultaneously excited by electrical signals, thereby transmitting ultrasonic waves at the same time; or the array elements participating in ultrasonic emission can also be excited by several electrical signals with a certain time interval, thereby continuously transmitting ultrasonic waves with a certain time interval.

[0084] The transmitting and receiving control circuit 20 is used to control the ultrasonic probe 10 to transmit ultrasonic waves and receive ultrasonic echo signals. For example, the transmitting and receiving control circuit 20 is used to control the ultrasonic probe 10 to transmit ultrasonic waves to the region of interest on the one hand, and to control the ultrasonic probe 10 to receive ultrasonic echo signals reflected by the ultrasonic waves from the region of interest on the other hand. In some specific embodiments, the transmitting and receiving control circuit 20 is used to generate a transmitting sequence and a receiving sequence, and output them to the ultrasonic probe 10. The transmitting sequence is used to control part or all of the multiple array elements in the ultrasonic probe 10 to transmit ultrasonic waves to the biological tissue 60. The parameters of the transmitting sequence include the number of array elements used for transmission and ultrasonic transmission parameters (such as amplitude, frequency, number of wave transmissions, transmission interval, transmission angle, waveform and / or focus position, etc.). The receiving sequence is used to control part or all of the multiple array elements to receive the echo of the ultrasonic wave after passing through the tissue. The parameters of the receiving sequence include the number of array elements used for reception and the receiving parameters of the echo (such as reception angle, depth, etc.). The ultrasonic parameters in the transmitting sequence and the echo parameters in the receiving sequence are different depending on the use of the ultrasonic echo or the image generated according to the ultrasonic echo.

[0085] The echo processing module 30 is used to process the ultrasonic echo signal received by the ultrasonic probe 10, for example, filtering, amplifying, beamforming, etc., to obtain ultrasonic echo data. In a specific embodiment, the echo processing module 30 can output the ultrasonic echo data to the processor 40, or store the ultrasonic echo data in a memory first, and when it is necessary to perform calculations based on the ultrasonic echo data, the processor 40 reads the ultrasonic echo data from the memory. Those skilled in the art should understand that in some embodiments, when it is not necessary to filter, amplify, beamform, etc., the ultrasonic echo signal, the echo processing module 30 can also be omitted.

[0086] The processor 40 is used to obtain ultrasonic echo data or signals, and use relevant algorithms to obtain the required parameters or images. The processor 40 in some embodiments of the present invention includes but is not limited to a central processing unit (CPU), a microcontroller unit (MCU), a field programmable gate array (FPGA), and a digital signal processing (DSP) device for interpreting computer instructions and processing data in computer software. In some embodiments, the processor 40 is used to execute various computer applications in the non-temporary computer-readable storage medium, so that the sample analysis device executes the corresponding detection process.

[0087] The display component 50 can be used to display information, such as displaying parameters and images calculated by the processor 40. Those skilled in the art should understand that in some embodiments, the ultrasound imaging system itself may not integrate a display module, but may be connected to a computer device (such as a computer) to display information through a display module (such as a display screen) of the computer device.

[0088] The above are some descriptions of the ultrasound imaging system.

[0089] Some embodiments further disclose a multi-modal combined ultrasonic measurement method. In some embodiments, the processor 40 is used to execute one step, multiple steps, or all steps in the multi-modal combined ultrasonic measurement method.

[0090] Please refer to Figure 2 In some embodiments, the multi-modal combined ultrasound measurement method comprises the following steps:

[0091] Step 100: Perform multi-modal combined ultrasound imaging to obtain multiple ultrasound images.

[0092] In some embodiments, the ultrasound imaging system can directly enter the multi-modality joint imaging mode.

[0093] For example, after the user selects multiple modes, or under the default multiple modes, the ultrasound imaging system enters the multi-modal joint imaging mode based on the user's operation (such as the instruction to enter the multi-modal imaging). In the multi-modal joint imaging mode, the processor 40 controls the ultrasound probe 10 to transmit and receive multi-modal ultrasound through the transmission and reception control circuit 20, and generates ultrasound images corresponding to the multiple modes. For example, the multiple modes can include B mode, shear wave elastic mode, viscous mode, acoustic attenuation mode and sound velocity mode, then the processor 40 can generate and control the display component 50 to display B mode image (B image), shear wave elastic mode image (shear wave elastic image), viscous mode image (viscous image) and acoustic attenuation mode image (acoustic attenuation image).

[0094] In some embodiments, the ultrasound imaging system may first enter a single-modality imaging mode and then enter a multi-modality combined imaging mode. A single imaging mode may include multiple types of images, such as a shear wave elasticity mode that generally includes a B image and a shear wave elasticity image.

[0095] For example, in response to the first modality imaging instruction, the processor 40 controls to enter the single-modality imaging mode of the first modality. In the single-modality imaging mode of the first modality, the processor 40 controls the ultrasound probe 10 to transmit and receive ultrasound waves of the first modality through the transmitting and receiving control circuit 20, and generates an ultrasound image of the first modality. For example, the first modality may be the B modality, and accordingly, the ultrasound image of the first modality is the B image. The user may observe through the B image and then switch to the multi-modality joint imaging mode, or may observe through the B image and select a region of interest on the B image, and then the user switches to the multi-modality joint imaging mode. The processor 40 controls the ultrasound probe 10 to transmit and receive ultrasound waves of the multi-modality through the transmitting and receiving control circuit 20, and generates ultrasound images corresponding to multiple modalities. For example, when a user switches from single-modality imaging of B mode to a multi-modality imaging mode including B mode, shear wave elastic mode, viscous mode and acoustic attenuation mode, the processor 40 generates and controls the display component 50 to display B-mode images (B images), shear wave elastic mode images (shear wave elastic images), viscous mode images (viscous images) and acoustic attenuation modality images (acoustic attenuation images).

[0096] Step 110 : Displaying the multiple ultrasound images obtained in step 100 .

[0097] It should be noted that the multiple ultrasound images displayed in step 110 may be all ultrasound images generated in step 100, or may be part of the ultrasound images generated in step 100. For example, images corresponding to four modalities are generated in step 100, and images corresponding to these four modalities may be displayed in step 110, or images of any three, any two, or any one of the images corresponding to these four modalities may be displayed. Modal images corresponding to multiple modalities may be displayed on the same display page at the same time, or images of multiple modalities may be displayed by switching display pages or display windows. For example, four display pages or four display windows are included, each page or each display window displays an image corresponding to a modality, and images of different modalities are displayed through section display pages or display windows.

[0098] In some embodiments, the multi-modality includes at least two of: B-mode, shear wave elastic mode, viscous mode, strain elastic mode, acoustic attenuation mode, ultrasound Doppler blood flow imaging mode, power Doppler imaging mode and ultra-micro blood flow imaging mode.

[0099] In some embodiments, the displayed multiple ultrasound images include at least two of the following: B image, elasticity image, viscosity image, acoustic attenuation image, sound velocity image, ultrasound Doppler blood flow image, power Doppler image and ultra-micro blood flow image.

[0100] Step 120: In response to a start instruction of the joint measurement mode, enter the joint measurement mode.

[0101] In some embodiments, a measurement control may be provided on the interface, and the user may click on the measurement control to cause the ultrasound imaging system to enter the joint measurement mode.

[0102] In some embodiments, the start instruction of the joint measurement mode may also be an instruction to enter the multimodal joint imaging mode, that is, these two instructions are the same instruction, and when the ultrasound imaging system enters the multimodal joint imaging mode, it also starts and enters the joint measurement mode at the same time.

[0103] The joint measurement mode is described below.

[0104] Step 121: Detecting a measurement ruler drawn on the ultrasound image, where the measurement ruler is used to define a tissue region.

[0105] There are many ways to draw a measurement scale on an ultrasound image. The following are some of them.

[0106] In some embodiments, step 121 detects a manually drawn measurement scale on the ultrasound image. For example, the user can manually draw the measurement scale through an input device of the ultrasound imaging system itself or an input device connected to the ultrasound imaging system; the input device can be a trackball, a touch screen, or a mouse.

[0107] In some embodiments, step 121 obtains a measuring ruler semi-automatically drawn on the ultrasound image by an auxiliary drawing method; wherein the auxiliary drawing method includes providing one or more measuring rulers with preset shapes, and providing operation instructions for moving, enlarging and / or reducing the measuring rulers with preset shapes. For example, the ultrasound imaging system provides a measuring ruler with a preset shape, such as a regular geometric shape or an irregular geometric shape such as a straight line, a curve, a circle, a rectangle, an ellipse, etc., and the user can operate the above-mentioned measuring ruler with a preset shape through an input device of the ultrasound imaging system itself or an input device connected to the ultrasound imaging system, such as moving, enlarging and reducing.

[0108] Step 122: When it is detected that a measuring scale is drawn on any one of the ultrasound images, other ultrasound images are acquired. Step 123: The measuring scale is synchronized to other ultrasound images so that the tissue area defined by the measuring scale on each ultrasound image is the same area. Step 124: The measuring scale on each ultrasound image is displayed.

[0109] In some embodiments, when an update to the measurement scale of any ultrasound image is detected, other ultrasound images are updated synchronously; in some embodiments, the update includes at least one of the following: adding a new measurement scale to the ultrasound image, adjusting the existing measurement scale on the ultrasound image, and deleting the existing measurement scale on the ultrasound image.

[0110] FIG3(a) is an example, which shows an interface. After clicking the joint measurement control 01, the joint measurement mode is entered. Of course, as mentioned above, the start instruction of the joint measurement mode can also be an instruction to enter the multimodal joint imaging mode, that is, these two instructions are the same instruction. When the ultrasound imaging system enters the multimodal joint imaging mode, the joint measurement mode is also started and entered at the same time.

[0111] Image A, Image B, Image C, and Image D are four ultrasound images obtained by multimodal combined ultrasound imaging, such as B image, elasticity image, viscosity image, and acoustic attenuation image. After a measurement scale L1 is drawn on Image A, the measurement scale L1 is also synchronized and displayed on Images B, C, and D, which is equivalent to drawing the measurement scale L1 on Images B, C, and D.

[0112] Further, please refer to Figure 3(b), the measurement scale L2 can continue to be drawn in Figure B, and the measurement scale L2 is also synchronized and displayed on images A, C and D, which is equivalent to drawing the measurement scale L2 in images A, C and D as well.

[0113] When the measurement scale is updated on any one of the ultrasound images among image A, image B, image C and image D, the measurement scales of the other ultrasound images will also be updated synchronously; for example, when the measurement scale L2 in image A is moved, the measurement scales L2 on image B, image C and image D will also be moved synchronously; for another example, when the measurement scale L2 in image C is enlarged, the measurement scales L2 on image A, image B and image D will also be enlarged synchronously; for another example, when the measurement scale L2 in image D is deleted, the measurement scales L2 on image A, image B and image C will also be deleted synchronously.

[0114] Step 128: For each ultrasound image, obtain measurement results related to the tissue region defined by its measurement scale on the ultrasound image based on the ultrasound image.

[0115] Step 129: Display the measurement results.

[0116] In the joint measurement mode, the user draws a measurement ruler on an ultrasound image, and the measurement ruler drawn on one ultrasound image will be synchronized to other ultrasound images. Not only are the measurement scales on each ultrasound image consistent, a large number of measurement results can be measured at one time, but the measurement results are also comparable.

[0117] In response to the start instruction of the combined measurement mode, when entering the combined measurement mode, the same measurement scales may be synchronously displayed on each ultrasound image. These measurement scales may be default or pre-set; in some embodiments, the user may update these measurement scales.

[0118] Therefore, please refer to Figure 4 In some embodiments, in the joint measurement mode: Step 126, obtain a measurement ruler, which is used to define the tissue area; Step 127, synchronously display the same measurement ruler on multiple ultrasound images so that the tissue area defined by the measurement ruler on each of the ultrasound images is the same area. In some embodiments, when an update to the measurement ruler of any ultrasound image is detected, other ultrasound images are updated synchronously; in some embodiments, the update includes at least one of the following: adding a new measurement ruler to the ultrasound image, adjusting the existing measurement ruler on the ultrasound image, and deleting the existing measurement ruler on the ultrasound image. Step 128: For each ultrasound image, obtain the measurement result related to the tissue area defined by its measurement ruler on the ultrasound image based on the ultrasound image; Step 129: Display the measurement result.

[0119] The above are some descriptions of the joint measurement mode.

[0120] In some embodiments, the multi-modal combined ultrasound measurement method also provides a single measurement mode; in some embodiments, in response to a start instruction of the single measurement mode, the single measurement mode is entered: Figure 5 is an example. By clicking the single measurement control 02, the ultrasound imaging system enters the single measurement mode. In the single measurement mode: when a measurement ruler is detected to be drawn on any ultrasound image, the measurement ruler is displayed on the ultrasound image, and the measurement ruler is prohibited from being synchronized to other ultrasound images. There are many ways to implement the measurement ruler drawn on the ultrasound image, which have been described above and will not be repeated here. .

[0121] The combined measurement mode and the single measurement mode can work together.

[0122] In some embodiments, when switching from the combined measurement mode to the single measurement mode: the measurement scale drawn on the ultrasound image in the combined measurement mode is retained in the single measurement mode. In this way, the user first draws the measurement scales of each ultrasound image in a unified manner in the combined measurement mode, and then can switch to the single measurement mode to draw a separate measurement scale on a specific ultrasound image, which takes into account both the universal measurement situation and some special measurement situations.

[0123] Let's take the above Figure 5 Take for example. The ultrasound imaging system first enters the joint measurement mode, and the user draws a measurement scale L1 in image A in the joint measurement mode, and the measurement scale L1 is also synchronously drawn and displayed on images B, C, and D; then it switches to the single measurement mode, and the measurement scale L1 drawn on the ultrasound image in the joint measurement mode is retained in the single measurement mode, that is, the measurement scale L1 on ultrasound images A, B, C, and D is retained in the single measurement mode; in the single measurement mode, the user draws a measurement scale L3 on image A. Since the ultrasound imaging system is currently in the single measurement mode, the measurement scale L3 drawn by the user on image A will not be synchronized to images B, C, and D.

[0124] In some embodiments, when switching from the single measurement mode to the combined measurement mode: the measurement scale drawn on the ultrasound image in the single measurement mode is retained in the combined measurement mode, and is prohibited from being synchronized with other ultrasound images in the combined measurement mode.

[0125] Let's still take the above Figure 5Take the example for explanation. The ultrasound imaging system first enters the single measurement mode, and the user draws the measurement scale L3 in image A in the single measurement mode. Since the ultrasound imaging system is currently in the single measurement mode, the measurement scale L3 drawn by the user on image A will not be synchronized to images B, C, and D; then it switches to the joint measurement mode, and the measurement scale L3 drawn on the ultrasound image in the single measurement mode is retained in the joint measurement mode, that is, the measurement scale L3 on the ultrasound image A is retained in the joint measurement mode, and the measurement scale L3 is prohibited from being synchronized to other ultrasound images in the joint measurement mode; in the joint measurement mode, the user draws the measurement scale L1 on image B again. Since the ultrasound imaging system is currently in the joint measurement mode, the measurement scale L1 is also synchronously drawn and displayed on images A, C, and D.

[0126] In some embodiments, when switching from the single measurement mode to the combined measurement mode: the measurement scale drawn on the ultrasound image in the single measurement mode is retained in the combined measurement mode and is synchronized with other ultrasound images in the combined measurement mode.

[0127] Please refer to Figure 6 , the ultrasound imaging system first enters the single measurement mode, and the user draws a measurement ruler L4 in image A in the single measurement mode. Since the ultrasound imaging system is currently in the single measurement mode, the measurement ruler L4 drawn by the user on image A will not be synchronized to image B, image C, and image D; then it switches to the joint measurement mode, and the measurement ruler L4 drawn on the ultrasound image in the single measurement mode is retained in the joint measurement mode, that is, the measurement ruler L4 on the ultrasound image A is retained in the joint measurement mode, and is synchronized to other ultrasound images in the joint measurement mode, that is, the measurement ruler L4 is also synchronously drawn and displayed on image B, image C, and image D; in the joint measurement mode, in the joint measurement mode, the user draws a measurement ruler L1 on image A again. Since the ultrasound imaging system is currently in the joint measurement mode, the measurement ruler L1 is also synchronously drawn and displayed on image B, image C, and image D.

[0128] The combined measurement mode and the single measurement mode are described above. The measurement scales involved are further described below.

[0129] In some embodiments, the measurement scale includes one or more of a first measurement scale, a second measurement scale, a third measurement scale, and a fourth measurement scale.

[0130] In some embodiments, the first measurement scale is a first closed boundary line for defining the first tissue region. In some embodiments, the first measurement scale is used to define lesion-related tissue, that is, the first tissue region is lesion-related tissue.

[0131] In some embodiments, the second measurement scale is a second closed boundary line for defining a second tissue region, where the second tissue region is obtained by expanding or contracting the first tissue region.

[0132] In some embodiments, the third measurement scale is a third closed boundary line for defining a third tissue region; the third tissue region is the difference between the first tissue region and the second tissue region; in some embodiments, the third closed boundary line is composed of the first closed boundary line and the second closed boundary line.

[0133] It can be seen that the third tissue region is a band-shaped region surrounding the first tissue region. After the third tissue region is defined by the third measuring scale, more information about the lesion can be obtained based on the measurement and analysis related to the third tissue region.

[0134] For example, the user can determine whether the lesion tissue in the first tissue area has an expansion tendency or a contraction tendency through the relevant measurement results of the third tissue area. The expansion tendency indicates that the lesion tissue in the first tissue area is further expanding and worsening, and the contraction tendency indicates that the lesion tissue in the first tissue area is gradually shrinking and the patient is recovering.

[0135] For example, in some modal measurements (such as elasticity or viscosity measurements), for some tissues, shear waves and ultrasound will be greatly attenuated when passing through these tissues, which makes the elastic detection of these tissues, such as the calculation of elastic parameters, unreliable and inaccurate. These tissues are typically some tissues with relatively high hardness. It should be emphasized and explained that these tissues with relatively high hardness can be normal tissues or lesion tissues - that is, both normal tissues and lesion tissues may have relatively high hardness. Since shear waves and ultrasound have not yet begun to attenuate or the attenuation is not so obvious when passing through the edge area of ​​the area of ​​interest (such as a harder tissue area), the elastic detection results of the edge area are relatively reliable and accurate. Therefore, in order to solve the problem of unreliable and inaccurate measurement results such as elastic detection results of these tissues with relatively high hardness, these tissues are taken as the first tissue area, and the third tissue area is focused on, and the measurement results related to the third tissue area, such as elastic parameters, are calculated to reflect the corresponding properties of the first tissue area, such as elasticity or hardness, and improve the reliability and accuracy of the measurement results of the first tissue area, such as elastic detection results.

[0136] For another example, the areas and boundaries of corresponding tissues on different modal images may show deviations. For example, the user generally draws a first measurement scale on the B image or the elasticity detection image to define the first tissue area. However, the tissue distribution characterized by the brightness distribution in the B image and the tissue distribution characterized by the hardness distribution on the elasticity detection image are not strictly corresponding. That is, the area and boundary of the same tissue on the B image may be different from its area and boundary on the elasticity detection image, that is, they are not strictly corresponding. Therefore, for the first tissue area defined by the first measurement scale, a third measurement scale is introduced to define the third tissue area, which serves to calibrate the problem that the area of ​​interest may deviate in different images due to the deviation in the distribution of the same tissue in different modal images.

[0137] The above are some explanations of the third measurement scale and the third tissue area.

[0138] In some embodiments, the fourth measurement scale is a fourth closed boundary line for defining a fourth tissue region. In some embodiments, the first tissue region and the fourth tissue region have no intersection.

[0139] Figure 7 It is a schematic diagram in which a first measuring scale, a second measuring scale, a third measuring scale and a fourth measuring scale are drawn on an ultrasonic image; in the figure, L10 represents the first measuring scale, and accordingly, the area defined by the first measuring scale L10 is the first tissue area; in the figure, L20 represents the second measuring scale, and accordingly, the area defined by the second measuring scale L20 is the second tissue area; L10 and L20 constitute the third measuring scale, and the annular area jointly defined by L10 and L20 (i.e., the difference between the first tissue area and the second tissue area) is the third tissue area; in the figure, L40 represents the fourth measuring scale, and accordingly, the area defined by the fourth measuring scale L40 is the fourth tissue area.

[0140] Figure 8(a) is a schematic diagram showing a first measuring scale, a second measuring scale, a third measuring scale and a fourth measuring scale on an ultrasound image A in a single measurement mode; Figure 8(b) is a schematic diagram showing a first measuring scale, a second measuring scale, a third measuring scale and a fourth measuring scale on an ultrasound image in a combined measurement mode.

[0141] In some embodiments, to distinguish different types of measurement scales, the first closed boundary line has a first color, the second closed boundary line has a second color, and the fourth closed boundary line has a fourth color. In some embodiments, at least two of the first color, the second color, and the fourth color are different colors.
