Description

Technical Field

[0001] This invention relates to the field of ultrasound imaging, and in particular to a method and system for measuring bladder volume. Background Technology

[0002] In related technologies, urinary system examinations typically involve measuring bladder volume using a cystometry device. Existing bladder volume measurement methods often rely on the user's experience and subjective judgment to control the probe's position and angle to locate the bladder. However, relying solely on the user's subjective probe placement makes it difficult to directly and successfully locate the bladder. Furthermore, the user cannot clearly determine the probe's next target direction of movement, resulting in prolonged positioning time and reduced measurement efficiency. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a method and system for measuring bladder volume that can indicate to the user the next direction of target movement of the detector.

[0005] When the detector rotates around the first direction, a corresponding initial cross-sectional image is acquired every time it rotates by a first preset angle;

[0006] The current location of the bladder is determined based on all the initial cross-sectional images, and corresponding prompts are generated and displayed; the prompts are used to prompt the user to move the detector.

[0007] After the detector moves, when the detector rotates around the first direction again, the corresponding current cross-sectional image is acquired at a second preset angle to calculate the bladder volume.

[0059] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0060] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, inside, outside, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0061] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0062] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0063] In related technologies, urinary system examinations typically involve measuring bladder volume using a cystometry device. Existing bladder volume measurement methods often rely on the user's experience and subjective judgment to control the probe's position and angle for bladder localization. Simply relying on the user's subjective probe placement is insufficient for successful bladder localization. Therefore, the probe needs to be moved after placement to locate the bladder. However, the user cannot determine the probe's next target direction of movement and can only move the probe randomly, resulting in prolonged localization time and reduced measurement efficiency.

[0064] Therefore, some embodiments of the present invention provide a method for measuring bladder volume, as detailed in the accompanying drawings. Figure 1 As shown.

[0065] In this embodiment of the invention, the method for measuring bladder volume can be applied to a measuring device. It is understood that in this embodiment, the measuring device can be an ultrasound measuring instrument, which may include a probe 500 and a detector 530 for acquiring cross-sectional images of the bladder 600. (Refer to...) Figure 5 , Figure 6 ,and Figure 7 As shown, the detector 530 can be disposed inside the probe 500, which can be held by a user. The detector 530 can rotate around a first direction 1000, thereby realizing a 360° detection scan of the measured position 700. Based on this, the first direction 1000 can be the direction of the line connecting the detector 530 and the measured position 700.

[0066] Reference Figure 1 As shown, in this embodiment of the invention, the measurement method may include:

[0067] Step S101: When the detector 530 rotates around the first direction 1000, the corresponding starting cross-sectional image is acquired every time it rotates by a first preset angle.

[0068] In this embodiment of the invention, a user can hold the probe 500 to scan the subject. The measured position 700 can be the starting position of the probe 500. It is understood that since it is difficult to successfully locate the bladder 600 in one attempt solely by the user's subjective placement of the probe 500, in this embodiment, the detector 530 can rotate around a first direction 1000. During the rotation, a corresponding initial cross-sectional image is acquired every time the probe rotates by a first preset angle. This initial cross-sectional image can be used as the basis for locating the bladder 600. It should be noted that the first preset angle can be 30°, 15°, or can be selected and set by those skilled in the art according to the actual situation; this embodiment does not limit this.

[0069] Reference Figure 5As shown, in this embodiment of the invention, the measuring device may further include a controller, a first driver 510 for driving the detector 530 to rotate around a first direction 1000, and a second driver 520 for driving the detector 530 to oscillate around a second direction 2000, wherein the second direction 2000 may be parallel to the measured position 700. The controller may be connected to the first driver 510 and the second driver 520 respectively to send command signals, the command signals including a first command and a second command. It is understood that the first driver 510 can drive the detector 530 to rotate around the first direction 1000 to achieve a 360° detection scan; the second driver 520 can drive the detector 530 to oscillate around the second direction 2000 to achieve the acquisition of the initial cross-sectional image. In this embodiment, the initial cross-sectional image may be a fan-shaped image obtained by ultrasound imaging.

[0070] In this embodiment of the invention, the measurement method can be applied to a controller, and step S101 may include:

[0071] In the first operation S1011, a first instruction is sent to the first driver 510; the first instruction is used to trigger the first driver 510 to drive the detector 530 to rotate around the first direction 1000 by a first preset angle.

[0072] In the second operation S1012, a second instruction is sent to the second driver 520 to obtain the corresponding initial cross-sectional image; the second instruction is used to trigger the second driver 520 to drive the detector 530 to swing around the second direction 2000.

[0073] It is understood that, in this embodiment of the invention, after receiving the first instruction, the first driver 510 can drive the detector 530 to rotate around the first direction 1000 by a first preset angle, for example, the first driver 510 drives the detector 530 to rotate from 0° to 30°. After the detector 530 completes its rotation, the second driver 520 can receive the second instruction, and the second driver 520 then drives the detector 530 to swing around the second direction 2000, thereby acquiring the initial cross-sectional image corresponding to the current angle. For example, if the detector 530 rotates to 30°, the acquired initial cross-sectional image will correspond to 30°. In this embodiment, the controller can repeat the first and second operations until the detector 530 rotates one full circle, that is, complete the 360° detection scan and acquire all the initial cross-sectional images.

[0074] Step S102: Confirm the current position of the bladder 600 based on all initial cross-sectional images, and generate and display corresponding prompt information; the prompt information is used to prompt the user to move the detector 530.

[0075] In this embodiment of the invention, the current position of the bladder 600 can be confirmed by analyzing and comparing all initial cross-sectional images, thus achieving accurate positioning of the bladder 600 after the user places the detector 530. It is understood that, based on confirming the current position of the bladder 600 and the initial position of the probe 500, the next target movement direction of the detector 530 can be determined. This embodiment can generate and display corresponding prompts based on the target movement direction to guide the user to move the probe 500 to the current position of the bladder 600, thereby achieving positioning of the bladder 600 by the probe 500, improving the accuracy of bladder 600 positioning, and significantly shortening the time required for bladder 600 positioning, thus improving the efficiency of bladder 600 positioning.

[0076] In step S103, after the detector 530 moves, when the detector 530 rotates around the first direction 1000 again, the corresponding current cross-sectional image is acquired at a second preset angle to calculate the bladder volume.

[0077] In this embodiment of the invention, after the user moves the probe 500 to the current position of the bladder 600 according to the prompts, the detector 530 can rotate again around the first direction 1000. During the rotation, it can acquire the corresponding current cross-sectional image at intervals of a second preset angle, thereby obtaining all current cross-sectional images. Based on all the current cross-sectional images, the corresponding data of the bladder 600 can be obtained, thereby calculating the bladder volume. In this embodiment, the second preset angle can be the same as or different from the first preset angle. It should be noted that the second preset angle can be 30° or 15°, and can also be selected and set by those skilled in the art according to the actual situation. This embodiment does not limit this.

[0078] The measuring device disclosed in this embodiment of the invention includes a detector 530 for acquiring cross-sectional images of a bladder 600. The detector 530 is rotatable around a first direction 1000, where the first direction 1000 is the direction of the line connecting the detector 530 and the measured position 700. The measurement method acquires a corresponding initial cross-sectional image each time the detector 530 rotates around the first direction 1000 by a first preset angle. The current position of the bladder 600 is confirmed based on all initial cross-sectional images, and corresponding prompt information is generated and displayed. The prompt information is used to prompt the user to move the detector 530. After the detector 530 moves, when the detector 530 rotates around the first direction 1000 again, a second preset interval is elapsed. The device acquires the corresponding current cross-sectional image to calculate the bladder volume. This allows for accurate positioning of the bladder 600 after the user places the detector 530, and provides prompts to the user based on the bladder 600's current position, indicating the next target movement direction of the detector 530. This reduces reliance on user experience and subjective feelings, improves the accuracy of bladder 600 positioning, significantly shortens the positioning time, and increases the efficiency of bladder 600 positioning, thereby improving the accuracy of bladder volume measurement and greatly enhancing measurement efficiency. Furthermore, the full interaction between the measuring device and the user improves the user experience.

[0079] Some embodiments of the present invention propose another method for measuring bladder volume, referring to... Figure 5 As shown, in this embodiment of the invention, the method for measuring bladder volume can be applied to a measuring device. The measuring device includes a detector 530 for acquiring a cross-sectional image of the bladder 600. The detector 530 is rotatable around a first direction 1000, which is the direction of the line connecting the detector 530 and the measured position 700.

[0080] Reference Figure 2 As shown, in this embodiment of the invention, the measurement method may include:

[0081] Step S201: When the detector 530 rotates around the first direction 1000, the corresponding starting cross-sectional image is acquired every time it rotates by a first preset angle.

[0082] It should be noted that for the specific implementation of the embodiments of the present invention, please refer to the description of the foregoing embodiments, which will not be repeated here.

[0083] Step S202: Identify the initial cross-sectional image with the maximum bladder width of 600 based on all initial cross-sectional images.

[0084] Step S203: After the detector 530 rotates to the angle corresponding to the initial cross-sectional image with the maximum bladder width 600, the target cross-sectional image 800 is acquired.

[0085] Reference Figure 6 and Figure 7 As shown, in this embodiment of the invention, the starting cross-sectional image with the maximum bladder width of 600 can be identified by comparing all starting cross-sectional images. Specifically, the starting cross-sectional image with the maximum bladder width of 600 among all starting cross-sectional images can be designated as the target cross-sectional image 800. For example, the starting cross-sectional image with the maximum bladder width of 600 among all starting cross-sectional images can be designated as the target cross-sectional image 800. Figure 6 The initial cross-sectional image with a maximum bladder width of 600 is calibrated as the target cross-sectional image 800, corresponding to a starting cross-sectional image at 0°. In this embodiment, the first actuator 510 can drive the detector 530 to rotate to the angle corresponding to the initial cross-sectional image with a maximum bladder width of 600. For example, as Figure 6 The initial cross-sectional image with a maximum bladder width of 600 is 0°. The first driver 510 can drive the detector 530 to rotate to 0°, and then the second driver 520 can drive the detector 530 to swing to obtain the target cross-sectional image 800 corresponding to 0°.

[0086] Step S204: Obtain the orientation information of the bladder 600 based on the target cross-sectional image 800, and generate prompt information corresponding to the orientation information.

[0087] In this embodiment of the invention, by analyzing and comparing the target cross-sectional image 800, the current position of the bladder 600 can be confirmed, enabling accurate positioning of the bladder 600 after the user places the detector 530. Based on confirming the current position of the bladder 600 and the starting position of the probe 500, the orientation information of the bladder 600 can be determined, thereby determining the next target movement direction of the detector 530. Therefore, this embodiment can generate and display corresponding prompts based on the orientation information to guide the user to move the probe 500 to the current position of the bladder 600 according to the prompts.

[0088] In step S205, after the detector 530 moves, when the detector 530 rotates around the first direction 1000 again, the corresponding current cross-sectional image is acquired at a second preset angle to calculate the bladder volume.

[0089] In this embodiment of the invention, step S205 may include:

[0090] Step S2051: Based on all current cross-sectional images, obtain all current edge data that correspond one-to-one with all current cross-sectional images.

[0091] Step S2052: Calculate the bladder volume based on all current edge data.

[0092] Reference Figure 7As shown, in this embodiment of the invention, after the detector 530 moves, the detector 530 can rotate again around the first direction 1000. During the rotation, it can acquire the corresponding current cross-sectional image at intervals of a second preset angle, thereby obtaining all current cross-sectional images. This embodiment can acquire the corresponding current edge data from the current cross-sectional image, thus enabling the detector 530 to rotate again around the first direction 1000. During the rotation, it can acquire the corresponding current cross-sectional image at intervals of a second preset angle, thereby obtaining all current cross-sectional images. In this embodiment, the bladder volume can be calculated using all the current edge data. Those skilled in the art can choose the calculation method according to the actual situation; this embodiment does not limit this method.

[0093] Some embodiments of the present invention propose another method for measuring bladder volume, referring to... Figure 5 As shown, in this embodiment of the invention, the method for measuring bladder volume can be applied to a measuring device. The measuring device includes a detector 530 for acquiring a cross-sectional image of the bladder 600. The detector 530 is rotatable around a first direction 1000, which is the direction of the line connecting the detector 530 and the measured position 700. The orientation information includes the target movement direction.

[0094] Reference Figure 3 As shown, in this embodiment of the invention, the measurement method may include:

[0095] Step S301: When the detector 530 rotates around the first direction 1000, the corresponding starting cross-sectional image is acquired every time it rotates by a first preset angle.

[0096] It should be noted that for the specific implementation of the embodiments of the present invention, please refer to the description of the foregoing embodiments, which will not be repeated here.

[0097] Step S302: Obtain the starting edge data of bladder 600 in each starting cross-sectional image.

[0098] Step S303: Calculate the bladder 600 width corresponding to each starting edge image based on the starting edge data.

[0099] In this embodiment of the invention, the initial cross-sectional image may contain the initial edge data of the bladder 600. Based on this, the width of the bladder 600 can be calculated according to the initial edge data. It is understood that in this embodiment, the initial edge data can be coordinate data. For example, this embodiment can obtain the coordinate data of the opposite ends in the initial cross-sectional image to calculate the width of the bladder 600. This embodiment can obtain the initial edge data of the bladder 600 in each initial cross-sectional image to calculate the width of the bladder 600 corresponding to each initial cross-sectional image.

[0100] Step S304: Compare the bladder 600 width corresponding to each initial cross-sectional image to identify the initial cross-sectional image with the largest bladder 600 width among all initial cross-sectional images.

[0101] In this embodiment of the invention, each initial cross-sectional image may have a corresponding bladder 600 width. By comparing the bladder 600 width corresponding to each initial cross-sectional image, the initial cross-sectional image with the largest bladder 600 width among all initial cross-sectional images can be identified.

[0102] Step S305: After the detector 530 rotates to the angle corresponding to the initial cross-sectional image with the maximum bladder width 600, the target cross-sectional image 800 is acquired.

[0103] It should be noted that for the specific implementation of the embodiments of the present invention, please refer to the description of the foregoing embodiments, which will not be repeated here.

[0104] Step S306: Divide the target cross-sectional image 800 into two regions.

[0105] Step S307: Determine the target movement direction based on the area where the bladder 600 is located.

[0106] Reference Figure 8 , Figure 9 and Figure 10 As shown, in this embodiment of the invention, the display device can display a target cross-sectional image 800, and divide the target cross-sectional image 800 into two regions by a dividing line. For example, the dividing line can be located in the center of the target cross-sectional image 800 and divide it into left and right regions. This embodiment can determine the target movement direction by determining the region where the bladder 600 is located. For example, referring to... Figure 8 As shown, the angle corresponding to the target cross-sectional image 800 is 150°. Based on this, the bladder 600 is located in the left region of the target cross-sectional image 800, so the target's movement direction is to the left along the 150° direction; refer to Figure 9 As shown, the angle corresponding to the target cross-sectional image 800 is 150°. Based on this, the bladder 600 is located in the right region of the target cross-sectional image 800, so the target's movement direction is to the right along the 150° direction; refer to Figure 10 As shown, the angle corresponding to the target cross-sectional image 800 is 150°. Based on this, part of the bladder 600 is located in the left region of the target cross-sectional image 800, and the other part is located in the right region of the target cross-sectional image 800. This indicates that the starting position of the probe 500 coincides with that of the bladder 600, and there is no need to move the probe 500.

[0107] Step S308: Generate and display prompt information corresponding to the target's movement direction.

[0108] It should be noted that for the specific implementation of the embodiments of the present invention, please refer to the description of the foregoing embodiments, which will not be repeated here.

[0109] Reference Figure 8 , Figure 9 and Figure 10 As shown, in this embodiment of the invention, the prompting information may include visual reference markers, and the measuring device further includes a display device for displaying the visual reference markers. The display device may also display a target cross-sectional image 800. In this embodiment, the visual reference markers can provide visual cues to the user for moving the probe 500. Specifically, step S308 may include:

[0111] Reference Figure 8 , Figure 9 and Figure 10 As shown, in this embodiment of the invention, the visual reference marker may include a center point 910 and multiple sets of directional marker groups 920. The center point 910 may correspond to a dividing line, and the multiple sets of directional marker groups 920 are arranged around the center point 910 at intervals of a first preset angle. Each set of directional marker groups 920 includes a first marker 921 and a second marker 922 pointing in opposite directions. The first marker 921 and the second marker 922 correspond one-to-one with two regions to characterize the target movement direction. For example, the first marker 921 and the second marker 922 are located on an extension line extending at 150° and pointing in opposite directions. Based on this, the first marker 921 located to the left of the center point 910 may correspond to the left region in the target cross-sectional image 800, and conversely, the first marker 921 located to the right of the center point 910 may correspond to the right region in the target cross-sectional image 800.

[0112] Step S30982: The pointing marker group 920 corresponding to the angle corresponding to the target cross-section image 800 is identified as the target marker group.

[0113] Step S30983: Highlight the first identifier 921 or the second identifier 922 in the target identifier group.

[0114] In this embodiment of the invention, the angle corresponding to the target cross-sectional image 800 is 150°, and the target identifier group is the pointing identifier group 920 located on the extension line extending along 150°. (Refer to...) Figure 8 As shown, when the bladder 600 is located in the left region of the target section image 800, the first identifier 921 can be highlighted; refer to Figure 9As shown, when the bladder 600 is located in the right region of the target cross-sectional image 800, the second identifier 922 can be highlighted, thereby prompting the user about the target's movement direction. It should be noted that in this embodiment, the highlighting can be a bright display, a color change display, or a shape change display, etc. Those skilled in the art can choose the appropriate setting based on the actual situation; this embodiment does not limit this.

[0115] In step S309, after the detector 530 moves, when the detector 530 rotates around the first direction 1000 again, the corresponding current cross-sectional image is acquired at a second preset angle to calculate the bladder volume.
