Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a method, testing device and storage medium for detecting peristaltic parameters. Background Technology

[0002] Current methods for detecting endometrial peristalsis using ultrasound primarily involve transvaginal ultrasound, where a doctor continuously observes changes in two-dimensional B-mode images over a period of time, or observes a stored video of B-mode images over a specific period to capture endometrial movement information and determine the amplitude, frequency, and direction of the peristaltic waves. On the one hand, this method relies on the doctor's subjective qualitative judgment, and different doctors may arrive at different conclusions. On the other hand, complex or subtle peristaltic movements are difficult to discern visually, hindering accurate assessment. Therefore, accurately detecting endometrial peristaltic parameters has become a pressing issue that needs to be addressed. Summary of the Invention

[0068] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0070] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0071] It should also be understood that the term "and / or" as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0072] Peristalsis is present in many organs and tissues of the human body, such as the intestines, stomach, and endometrium. This invention continuously emits ultrasound waves to these peristaltic organs or tissues for a period of time and detects the echoes to calculate the peristaltic displacement or velocity of the organs or tissues at different times, thereby providing an objective evaluation of the peristaltic state of the organs or tissues. The specific process will be described in detail below. In the following description, the measurement of peristaltic parameters of the endometrium is mainly used as an example. However, those skilled in the art should understand that this invention is not limited to the endometrium, and the methods and devices in the following embodiments are also applicable to measuring the peristaltic parameters of other tissues, such as the intestines, stomach, etc. In this document, these peristaltic tissues for which peristaltic parameters will be measured are referred to as "peristaltic targets".

[0073] Embodiments of this application provide a method, a detection device, and a storage medium for detecting peristaltic parameters. The method for detecting peristaltic parameters can be applied in the detection device to detect the peristaltic parameters of biological tissues, such as the peristaltic parameters of the endometrium. These peristaltic parameters include displacement and velocity information, etc., to accurately determine the peristaltic status of the endometrium.

[0074] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0075] Please see Figure 1 , Figure 1 This is a schematic block diagram of a peristalsis parameter detection device provided for an embodiment of this application. The detection device 10 may include a processor 11, a memory 12, a probe 13, a display 14, a transmit / receive selection switch 15, a transmit circuit 16, a receive circuit 17, and a beamforming circuit 18.

[0076] The transmitting circuit 16 excites the probe 13 to emit ultrasound waves towards the endometrium. The receiving circuit 17 receives the echo of the ultrasound waves returning from the endometrium via the probe 13, thereby obtaining an echo signal. This echo signal is processed by the beamforming circuit 18 and then sent to the processor 11. The processor 11 processes the echo signal to obtain peristaltic parameters of the endometrium, such as displacement or velocity. The peristaltic parameters obtained by the processor 11 can be stored in the memory 12 for display on the display 14.

[0077] In one embodiment, the display 14 of the detection device 10 may be a touch screen, liquid crystal display, or OLED display, or it may be a liquid crystal display, television, or independent display device separate from the detection device 10, or it may be a display screen on an electronic device such as a mobile phone or tablet computer, etc.

[0078] In practical applications, processor 11 can be a Central Processing Unit (CPU), or it can be other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or any conventional processor, thereby enabling processor 11 to execute the corresponding steps of the peristalsis parameter detection method in the various embodiments of this application.

[0079] The memory 12 may be volatile memory, such as random access memory (RAM); or non-volatile memory, such as read-only memory (ROM), flash memory, hard disk drive (HDD), or solid-state drive (SSD); or a combination of the above types of memory, and provide instructions and data to the processor.

[0080] The probe 13, under the control of the processor 11 and the transmitting circuit 16, can emit ultrasonic waves with different parameters, such as different frequencies and intensities.

[0081] Probe 13 includes various types of probes, such as convex probes or linear probes. Different types of probes have different control methods for the direction of ultrasound emission towards the endometrium. For example, the probe can be mechanically rotated or different probe array elements can be electronically selected. The control method for the receiving direction is the same as that for the transmitting direction.

[0082] For example, such as Figure 2 As shown, probe 13 includes multiple probe array elements 130, which are used to transmit and receive ultrasound waves. Specifically, whether to transmit or receive ultrasound waves can be determined by processor 11 through transmit / receive selection switch 15. More specifically, one probe array element 130 can be selected to transmit ultrasound waves to the endometrium 20, or multiple probe array elements 130 can be selected to form a subset of transmitting array elements to transmit ultrasound waves to the endometrium 20.

[0083] For example, in Figure 2 In this process, four probe array elements 130 are selected to form a transmitting array element subset 131, and the transmitting array element subset 131 is controlled to transmit ultrasound waves to the endometrium 20. The direction in which the transmitting array element subset 131 transmits ultrasound waves to the endometrium 20 is the transmission direction, namely the transmission direction D1.

[0084] For example, in Figure 3 In this process, four probe array elements 130 located at different positions are selected to form a transmitting array element subset 131 and a transmitting array element subset 132. Both transmitting array element subset 131 and transmitting array element subset 132 emit ultrasound waves to the endometrium 20, but the corresponding transmitting directions are different, corresponding to transmitting direction D1 and transmitting direction D2 respectively.

[0085] It should be noted that, through the control of the transmit / receive selection switch 15, the transmit element subsets 131 and 132 can also be used as receive element subsets. Of course, other probe elements 130 of different numbers or positions can also be selected to form the transmit element subsets, such as selecting two or three probe elements.

[0086] In some embodiments, to better receive ultrasound waves returned from the endometrium 20, the transmission and reception directions can be made the same. This means that identical probe elements 130 can be selected to form both the transmitting and receiving subsets. Specifically, the number of probe elements 130 in both subsets is the same, and the positions of these multiple probe elements 130 within the probe 13 are also identical. For example, the transmitting subset 131 can be used to transmit ultrasound waves and similarly serves as the receiving subset to receive the echoes of those ultrasound waves.

[0087] It should be noted that, in the embodiments of this application, the endometrium 20 can be the entire endometrium or a part of the endometrium, that is, it represents a local location area of ​​the endometrium. The endometrium 20 can include multiple local location areas, which are local areas formed by dividing the endometrium.

[0088] The following will provide a detailed description of the method for detecting peristaltic parameters provided in the embodiments of this application, taking into account the specific structure and working principle of the detection device 10 and the probe 13.

[0089] Please see Figure 4 , Figure 4 This is a schematic flowchart illustrating a method for detecting peristaltic parameters provided in an embodiment of this application. Figure 4 As shown, the method for detecting the peristalsis parameter specifically includes steps S101 to S106.

[0090] S101. Emit a first ultrasound wave to the endometrium and receive the echo of the first ultrasound wave to obtain the ultrasound echo signal of the first ultrasound wave.

[0091] Specifically, the probe is controlled to emit a first ultrasound wave towards the endometrium and receive the echo of the first ultrasound wave to obtain the ultrasound echo signal of the first ultrasound wave. The first ultrasound wave can be an ultrasound wave used for imaging the endometrium, such as the ultrasound waves corresponding to B-mode ultrasound images, C-mode ultrasound images, M-mode ultrasound images, etc.

[0092] The first and second ultrasonic waves can be ultrasonic waves with the same parameters or ultrasonic waves with different parameters. For example, changing the transmission frequency or operating voltage of the probe can make the parameters of the first and second ultrasonic waves different. The first and second ultrasonic waves can also be emitted in the same or different ways. For example, the first ultrasonic wave can be emitted using a divergent wave method, while the second ultrasonic wave can be emitted using a focused wave method.

[0093] S102. Obtain an ultrasound image of the endometrium based on the ultrasound echo signal of the first ultrasound wave.

[0094] Specifically, the endometrium is imaged based on the echo of the first ultrasound wave to obtain an ultrasound image of the endometrium. For example, the ultrasound image of the endometrium can be a B-image. In other embodiments, other types of images can also be obtained, such as M-images or C-images, etc., which are not limited here.

[0095] After obtaining the ultrasound image of the endometrium, the ultrasound image can be displayed on the monitor of the detection device. This allows the user to observe the detection process of peristalsis parameters through the ultrasound image. Because the endometrial movement detection time is relatively long (e.g., tens of seconds or minutes), if the user operates improperly, causing probe displacement or poor contact, etc., this can be detected and adjusted in time through the synchronous ultrasound image.

[0096] S103. Determine the region of interest based on the ultrasound image.

[0097] Specifically, the region of interest (ROI) is determined based on the ultrasound image of the endometrium. This can be achieved by identifying features within the ultrasound image, such as identifying characteristic structures to determine the region containing one or more of these features. Alternatively, the ultrasound image can be displayed, allowing the user to select the ROI on the image.

[0098] For example, by obtaining the region of interest selected by the user on the ultrasound image, the specific process is as follows: display the ultrasound image of the endometrium, obtain the border selected by the user in the ultrasound image, and use the area corresponding to the border as the region of interest. This not only allows for rapid identification of the region of interest but also improves the user experience.

[0099] For example, such as Figure 5 As shown, an ultrasound B-image 21 is displayed on the monitor. If the user selects a region of interest in the ultrasound B-image 21 and forms a border, the border selected by the user in the ultrasound image is obtained and the region corresponding to the border is taken as the region of interest 210.

[0100] S104. A second ultrasonic wave is emitted toward the region of interest in at least two emission directions, and the echo of the second ultrasonic wave is received to obtain at least two sets of echo signals.

[0101] Each set of echo signals corresponds to each transmission direction and includes echo signals at at least two time points. That is, each transmission direction receives a set of echo signals, and each set of echo signals includes echo signals at multiple time points.

[0102] Specifically, the probe is controlled to emit a second ultrasound wave towards the endometrium in at least two emission directions, and the probe is controlled to receive the echoes of the second ultrasound wave, thereby obtaining at least two sets of echo signals. The direction in which the echoes of the second ultrasound wave are received can be the same as the direction of emission of the second ultrasound wave, or it can be different from the direction of emission of the second ultrasound wave, or multiple receiving directions can be used to receive the echoes of the second ultrasound wave from the same emission direction.

[0103] In one embodiment, a second ultrasonic wave can be emitted toward the region of interest in at least two transmission directions, and the echo of the second ultrasonic wave can be received in the same direction as the transmission direction to obtain at least two sets of echo signals. That is, the direction of receiving the echo of the second ultrasonic wave is the same as the direction of emitting the second ultrasonic wave. It should be noted that the direction of receiving and the direction of transmission being the same includes two directions that are exactly the same or two directions that are approximately the same. "Exactly the same" means two parallel directions, while "approximately the same" means that the direction of receiving and the direction of transmission are not completely parallel, but have a certain tilt angle relative to each other. However, the tilt angle must be within a preset range, such as within 5° or within 10°. Both can be considered as the two directions being approximately the same.

[0104] For example, such as Figure 6 As shown, the transmitting element subsets 131 and 132 of the control probe 13 transmit second ultrasound waves to the endometrium 20 in transmitting directions D1 and D2, respectively. The transmitting element subsets 131 and 132 of the control probe 13 also serve as receiving element subsets, receiving the echoes of the second ultrasound waves in receiving directions D1' and D2'. Specifically, transmitting direction D1 and receiving direction D1' are in the same direction, and transmitting direction D2 and receiving direction D2' are in the same direction.

[0105] For example, such as Figure 7 As shown, the transmission direction D1 and the receiving direction D1', as well as the transmission direction D2 and the receiving direction D2', are not completely parallel, but rather have a relative tilt angle. Specifically, the receiving array subsets 131' and 132' can select different probe elements 130 from the transmitting array subsets 131 and 132, thus causing the transmission direction and the receiving direction to be approximately the same.

[0106] In some embodiments, emitting a second ultrasound wave toward the endometrium in at least two emission directions may include emitting a second ultrasound wave toward the endometrium in three or more emission directions, such as... Figure 8 As shown, four probe array elements 130 are selected to form transmitting array element subsets 131, 132, and 133, which transmit the second ultrasonic wave in transmission directions D1, D2, and D3, respectively, and receive the echo of the second ultrasonic wave in receiving directions D1', D2', and D3'. Of course, more transmission directions can be selected for transmission, and the different transmission directions do not need to be on the same plane. For each second ultrasonic wave transmitted in a transmission direction, the echo of the second ultrasonic wave can be received in a receiving direction in the same direction as the transmission direction to obtain at least two sets of echo signals.

[0107] Specifically, a second ultrasound wave is emitted toward the endometrium in at least two transmission directions, and the echo of the second ultrasound wave is received to obtain at least two sets of echo signals. The corresponding ultrasound wave transmission and reception methods include at least two methods, namely: transmission and reception method one and transmission and reception method two.

[0108] Transmit / receive method 1:

[0109] This transmission and reception method involves transmitting and receiving a second ultrasound wave to the endometrium by changing the transmission direction. Specifically, it includes: transmitting a second ultrasound wave to the endometrium in one transmission direction and receiving the echo of the second ultrasound wave; changing the transmission direction to transmit the second ultrasound wave to the endometrium in the changed transmission direction and receiving the echo of the second ultrasound wave in the changed transmission direction; repeating the process of transmitting the second ultrasound wave in one transmission direction and receiving the echo of the second ultrasound wave, and changing the transmission direction to transmit the second ultrasound wave in the changed transmission direction and receiving the echo of the second ultrasound wave, to obtain at least two sets of echo signals, wherein each set of echo signals corresponds to each transmission direction at different times.

[0110] Specifically, such as Figure 9As shown, at time T1, a second ultrasound wave is first emitted towards the endometrium in the transmission direction D1 and received in the receiving direction D1', which is in the same direction as the transmission direction D1. At time T2, the transmission direction D1 is changed to the transmission direction D2, and the second ultrasound wave is emitted towards the endometrium in the transmission direction D2, and received in the receiving direction D2', which is in the same direction as the transmission direction D2. At time T3, the second ultrasound wave is emitted again in the transmission direction D1 and the echo of the second ultrasound wave is received. At time T4, the transmission direction is changed again, and the second ultrasound wave is emitted again in the transmission direction D2 and the echo of the second ultrasound wave is received. The above transmission and reception process is repeated continuously to obtain echoes at multiple times, thus obtaining two sets of echo signals. That is, the echoes corresponding to T1, T3... form one set of echo signals corresponding to the transmission direction D1, and the echoes corresponding to T2, T4... form another set of echo signals corresponding to the transmission direction D2.

[0111] It should be noted that if the above includes three or four transmission directions, three or four sets of echo signals will be obtained in the end. More transmission directions will result in more sets of echo signals.

[0112] In one embodiment, a second ultrasound wave is emitted toward the endometrium in at least two emission directions, wherein the second ultrasound wave includes a focused wave, a plane wave, a divergent wave, or a weakly focused wave. This can improve the coverage of the target area of ​​the endometrium.

[0113] Specifically, in order to effectively cover the entire area of ​​the endometrium to be examined, plane wave emission, divergent wave emission, or weakly focused emission methods are used for ultrasound transmission. In this case, only one transmission is needed to retrieve all echo signals from the entire area to be examined.

[0114] In one embodiment, the region of interest in the endometrium includes multiple localized regions, such as... Figure 10 As shown, for example, it includes three local location regions, namely local location region S1, local location region S2 and local location region S3.

[0115] Accordingly, transmitting a second ultrasonic wave toward the region of interest in one transmission direction and receiving the echo of the second ultrasonic wave includes: transmitting the second ultrasonic wave toward various local locations within the region of interest in one transmission direction and receiving the echo of the second ultrasonic wave; transmitting the second ultrasonic wave toward the region of interest in a changed transmission direction and receiving the echo of the second ultrasonic wave after the changed transmission direction includes: transmitting the second ultrasonic wave toward various local locations within the region of interest in the changed transmission direction and receiving the echo of the second ultrasonic wave after the changed transmission direction. Receiving the received echo of the second ultrasonic wave yields at least two sets of echo signals, each set of echo signals corresponding to each transmission direction and local region and including echo signals at at least two time points.

[0116] Taking the reception of the second ultrasonic echo in the same direction as the transmission direction as an example, such as Figure 10 As shown, at time T1, a second ultrasound wave is first emitted in the transmission direction D1 towards three local regions (S1, S2, and S3) of the region of interest, and the echo of the second ultrasound wave is received in the receiving direction D1', which is in the same direction as the transmission direction D1. At time T2, the transmission direction D1 is changed to the transmission direction D2, and the second ultrasound wave is emitted in the transmission direction D2 towards the three local regions (S1, S2, and S3) of the endometrium, and the echo of the second ultrasound wave is received in the receiving direction D2', which is in the same direction as the transmission direction D2. At time T3, the second ultrasound wave is emitted again in the transmission direction D1 and the echo of the second ultrasound wave is received. At time T4, the second ultrasound wave is emitted again in the transmission direction D2 and the echo of the second ultrasound wave is received. The above transmission and reception process is repeated continuously to obtain echoes at multiple times, thereby obtaining two sets of echo signals at the local location S1, namely, one set of echo signals at the local location S1 in the direction of D1' at times T1, T3..., and another set of echo signals at the local location S1 in the direction of D2' at times T2, T4.... Similarly, two sets of echo signals can be obtained at local location regions S2 and S3. By combining the two sets of echo signals at local location regions S1, S2 and S3, two sets of echo signals for the entire region of interest can be obtained.

[0117] Transmit / receive method two:

[0118] The region of interest (ROI) comprises multiple local location regions. This transmission and reception method involves transmitting and receiving ultrasonic waves to the ROI by altering the local location regions. Specifically, it includes: transmitting a second ultrasonic wave to a local location region of the ROI from at least two transmission directions and receiving the echo of the second ultrasonic wave; changing the local location region and transmitting ultrasonic waves to the changed local location region from at least two transmission directions, and receiving the echo of the changed second ultrasonic wave from the changed local location region; repeating the process of transmitting the second ultrasonic wave to a local location region and receiving the echo of the second ultrasonic wave, and changing the local location region and transmitting the second ultrasonic wave to the changed local location region and receiving the echo of the changed second ultrasonic wave from the changed local location region, until second ultrasonic waves are transmitted to multiple local location regions, resulting in at least two sets of echo signals. Each set of echo signals corresponds to each transmission direction and local region and includes echo signals from at least two time points.

[0119] Taking the reception of the second ultrasonic echo in the same direction as the transmission direction as an example, such as Figure 11 As shown, assume that the region of interest includes two local location regions, namely local location region S1 and local location region S2. At time T1, a second ultrasonic wave is emitted into local location region S1 via three emission directions D1, D2, and D3, and the echo of the second ultrasonic wave is received via receiving directions D1', D2', and D3', which are in the same direction as the emission directions D1, D2, and D3. The local location region S1 is then changed to local location region S2. At time T2, the second ultrasonic wave is emitted into local location region S2 via the three emission directions D1, D2, and D3, and the echo of the second ultrasonic wave is received via receiving directions D1', D2', and D3', which are in the same direction as the emission directions D1, D2, and D3. This process is repeated until the second ultrasonic wave is emitted into multiple local location regions. That is, at time T3, the process of emitting and receiving the echo of the second ultrasonic wave into local location region S1, and then changing to local location region S2, emitting and receiving the echo of the second ultrasonic wave into local location region S2 at time T4, is repeated. This results in at least three sets of echo signals for each local location region, and each set of echo signals includes echo signals from at least two time points. For a local location region S1, the first set of echo signals includes echoes in the D1' direction at times T1, T3..., the second set of echo signals includes echoes in the D2' direction at times T1, T3..., and the third set of echo signals includes echoes in the D3' direction at times T1, T3.... Similarly, at least three sets of echo signals for a local location region S2 can be obtained. By combining at least three sets of echo signals from local location regions S1 and S2, at least three sets of echo signals for the entire region of interest can be obtained.

[0120] It should be noted that the local location region can be a location region defined by the user based on the region of interest. Therefore, the region of interest may include multiple local location regions, and these multiple local location regions can be arranged in an order, such as in rows or columns. Thus, ultrasonic waves can be emitted sequentially to multiple local location regions according to their arrangement, such as in a row-by-row or column-by-column arrangement, thereby shortening the emission time and improving emission efficiency. Alternatively, the local location region can be automatically defined by the system. The number of local location regions defined can be determined based on the size of the region of interest, and these multiple local location regions can also be arranged in an order.

[0121] When the region of interest includes multiple local locations, for the first transmission and reception method, if the number of local locations is too large, it may result in a large time interval between transmission and detection in the same direction for any local location. This leads to a long time interval between the echoes of the second ultrasonic waves based on the same local location and the same transmission direction, resulting in a large calculation error for the creep motion component of that local location in the transmission direction, and thus some distortion in the final calculation result of the creep parameters.

[0122] In one embodiment, to improve the accuracy of the peristaltic parameters, the method further includes, before step S101: obtaining the number of local location regions of interest; if the number of local location regions of interest is greater than a preset number, selecting the second transmission and reception mode to transmit and receive ultrasonic waves in each local location region of interest to obtain at least two sets of echo signals; or using the first transmission and reception mode and employing focused wave, plane wave, divergent wave, or weakly focused wave transmission methods. By switching the transmission and reception modes, the detection efficiency of the peristaltic parameters is improved.

[0123] S105. Calculate the peristaltic motion component of the endometrium in the region of interest in the emission direction corresponding to each set of echo signals, thereby obtaining at least two peristaltic motion components.

[0124] Specifically, a peristaltic motion component of the endometrium within the region of interest can be calculated based on each set of echo signals. Two sets of echo signals yield two peristaltic motion components, each corresponding to the emission direction of each set of echo signals. These peristaltic motion components can be displacement or velocity.

[0125] For example, such as Figure 9As shown, two sets of echo signals are obtained: one set corresponds to echo signals at times T1, T3, ..., and the other set corresponds to echo signals at times T2, T4, ... From this, a creeping motion component can be calculated based on the echo signal corresponding to times T1 and T3. This echo signal corresponds to the transmission direction D1, and the creeping motion component is the creeping motion component in the D1 direction. Similarly, another creeping motion component can be calculated based on the echo signal corresponding to times T2 and T4. This echo signal corresponds to the transmission direction D2, and the creeping motion component is the creeping motion component in the D2 direction. Thus, at least two creeping motion components can be obtained.

[0126] For example, such as Figure 10 As shown, the region of interest can include multiple local locations, such as local location S1, local location S2, and local location S3. By emitting a second ultrasonic wave towards each local location within the region of interest in one direction and receiving the echoes, changing the emission direction, and then emitting the second ultrasonic wave towards each local location within the region of interest in the changed direction while receiving the echoes, this process can be repeated to obtain at least two sets of echo signals corresponding to each local location. Therefore, at least two peristaltic motion components corresponding to that local location can be obtained from these at least two sets of second ultrasonic echo signals. For example, the peristaltic motion component in the D1 direction of local location S1 can be calculated from the echo signals at times T1 and T3 in one set of echo signals emitted from local location S1 in direction D1, and the peristaltic motion component in the D2 direction of local location S1 can be calculated from the echo signals at times T2 and T4 in another set of echo signals emitted from local location S1 in direction D2.

[0127] For example, such as Figure 11 As shown, a second ultrasonic wave is emitted towards a local location region of interest in at least two transmission directions, and the echo of the second ultrasonic wave is received; the local location region is changed, and the second ultrasonic wave is emitted towards the changed local location region in at least two transmission directions, and the echo of the changed second ultrasonic wave is received. This process is repeated to obtain at least two sets of echo signals corresponding to each local location region. Figure 11As shown, at least three sets of echo signals can be obtained. The first set of echo signals includes echoes in the D1' direction at times T1, T2, T3, T4... of the local location region S1; the second set of echo signals includes echoes in the D2' direction at times T1, T2, T3, T4... of the local location region S1; and the third set of echo signals includes echoes in the D3' direction at times T1, T2, T3, T4... of the local location region S1. Therefore, at least two echo signals from each set of local location region S1 can be selected to calculate the corresponding peristaltic motion components. Thus, the peristaltic motion components of local location region S1 in the three emission directions D1, D2, and D3 can be obtained. Similarly, the peristaltic motion components of local location region S2 in the three emission directions D1, D2, and D3 can be obtained. By combining the peristaltic motion components of local location regions S1 and S2 in each direction, the overall peristaltic motion components of the region of interest can be obtained.

[0128] For a target in space, such as the endometrium, ultrasound waves are continuously emitted for a period of time and the echoes of the ultrasound waves are received. If the target is in motion, based on the peristalsis detection method, the peristaltic displacement or peristaltic velocity of the endometrium can be detected according to the echoes of the ultrasound waves obtained at different times. The displacement and velocity can be converted by d = v * t.

[0129] In one embodiment, the peristaltic motion component of the endometrium within the region of interest in the emission direction corresponding to each set of echo signals is calculated based on each set of echo signals. The calculation method includes: based on a module matching algorithm, calculating the peristaltic motion component of the endometrium within the region of interest in the emission direction corresponding to each set of echo signals.

[0130] For example, using the block-matching algorithm, for the echo signal at a target location at a certain time, the target location is a local location in the region of interest. At another time, different locations of the echo signal are searched to find the location with the largest cross-correlation. The creep displacement of the region of interest can be calculated based on the difference between the largest location and the original location. This creep displacement is the creep motion component.

[0131] In one embodiment, the peristaltic motion component of the endometrium within the region of interest in the emission direction corresponding to each set of echo signals is calculated based on each set of echo signals. The calculation method includes: based on the Doppler method, calculating the peristaltic motion component of the endometrium within the region of interest in the emission direction corresponding to each set of echo signals.

[0132] Specifically, based on the ultrasonic Doppler effect, the motion velocity of a target location at various times is detected. By receiving the frequency of the echo of the ultrasonic wave transmitted to the region of interest, and using the ultrasonic Doppler effect based on the frequency of the echo, as well as the propagation speed and transmission frequency of the ultrasonic wave, the creep velocity of the region of interest can be calculated. This creep velocity is the creep motion component.

[0133] S106. Determine the peristaltic parameters of the endometrium based on at least two peristaltic motion components.

[0134] Specifically, the peristaltic parameters of the endometrium are determined based on multiple peristaltic motion components. These parameters describe the motion state of the endometrium. In particular, multiple peristaltic motion components are synthesized to determine the motion vector corresponding to the endometrium; and the peristaltic parameters corresponding to the endometrium are determined based on the motion vector.

[0135] For example, taking the determination of the peristaltic velocity vector using the peristaltic velocity component as an example, such as... Figure 14 As shown, the velocity component of point M in the D1 direction is V1, and the velocity component in the D2 direction is V2. Based on the velocity component V1, the first reference line L1 perpendicular to the D1 direction can be determined, and based on the velocity component V2, the second reference line L2 perpendicular to the D2 direction can be determined. The creep velocity vector V of the target point can be determined by connecting the intersection point O of the target point M with the first reference line L1 and the second reference line L2.

[0136] For example, the peristaltic motion components in three different directions can be synthesized to obtain the peristaltic motion vector. This can be achieved by combining the velocity components in three different directions into a vector velocity in three-dimensional space. The number of motion components in the synthesized peristaltic motion vector is unlimited. Furthermore, peristaltic parameters can be determined from the peristaltic motion vector. These parameters can be the motion vector itself, or quantitative or qualitative parameters describing endometrial peristalsis derived from the peristaltic parameters.

[0137] In one embodiment, the peristalsis parameter includes at least one statistic of the peristaltic motion component or at least one statistic of the motion vector synthesized from the peristaltic motion component, and the peristalsis parameter may also be characterized by one of the peristaltic motion components.

[0138] In one embodiment, the peristaltic parameters mentioned herein may include at least one of the following: peristaltic amplitude, peristaltic frequency, total significant peristaltic movement time within a preset duration, peristaltic propagation direction, peristaltic propagation speed, peristaltic range, etc.

[0139] In one embodiment, the peristaltic parameter can also be other parameters related to the peristaltic displacement or peristaltic velocity that reflect the motion state, calculated based on peristaltic displacement or peristaltic velocity, such as at least one of the following: tissue strain caused by peristalsis, tissue strain rate caused by peristalsis, acceleration of peristaltic movement, etc. Furthermore, in one embodiment, the peristaltic parameter can also be at least one statistic of peristaltic displacement or peristaltic velocity, such as maximum peristaltic displacement, minimum peristaltic displacement, mean peristaltic displacement, variance peristaltic displacement, maximum peristaltic velocity, minimum peristaltic velocity, mean peristaltic velocity, variance peristaltic velocity, etc.

[0140] Peristalsis is typically regular and periodic, propagating from one point in the endometrium to other locations, much like the propagation of vibrational waves. Therefore, peristaltic waves are often used in this field to describe peristalsis, and the specific peristaltic parameters mentioned above can be wave-like parameters. Peristaltic parameters can be calculated within a preset duration. This preset duration can be selected as the primary focus period for clinicians, such as 1 minute or 30 seconds, but is usually chosen to be greater than or equal to the peristaltic cycle to ensure that at least one complete peristalsis can be detected.

[0141] In some clinical situations, peristalsis may also be irregular or disordered. Therefore, the aforementioned peristaltic parameters can also be parameters that reflect the irregular or disordered state of peristaltic movement, such as the degree of disorder of peristaltic movement, the degree of unevenness of peristaltic amplitude, the degree of unevenness of peristaltic direction, and the distribution of peristaltic movement in the endometrium.

[0142] In general ultrasound detection, the positions and directions of ultrasound wave transmission and reception are fixed. Therefore, the displacement data (or velocity data) calculated from the acquired ultrasound echo signals mainly reflects the motion information in the current direction (detection direction). However, the actual direction of tissue movement may differ from the detection direction, resulting in a significant discrepancy between the detection results and the actual motion vector, leading to low accuracy of the detected peristaltic parameters. In the embodiments of this application, peristaltic motion components in multiple detection directions are calculated, and the peristaltic parameters of the endometrium are determined based on these components, thereby improving the accuracy of the peristaltic parameters.

[0143] It should be noted that, in one embodiment, the first and second ultrasound waves are emitted alternately. Specifically, the probe is controlled to alternately emit the first and second ultrasound waves towards the endometrium, wherein the second ultrasound wave is emitted towards the endometrium in at least two directions, while the direction of the first ultrasound wave is not limited.

[0144] For example, such as Figure 12As shown, a first ultrasound wave B is first emitted to the endometrium, followed by a second ultrasound wave A at time T1, then the first ultrasound wave B is emitted again, and then the second ultrasound wave A is emitted again at time T2, and this cycle continues until the set detection time ends. Alternatively, the second ultrasound wave A can be emitted first, followed by the first ultrasound wave B, as long as the emission is alternating. In another embodiment, the first ultrasound wave can be interspersed among the second ultrasound waves, or vice versa, as long as the received echo signal of the first ultrasound wave is sufficient for complete ultrasound imaging and at least two sets of second ultrasound wave echo signals are received. The specific alternation method is not limited.

[0145] The peristaltic parameter detection method disclosed in the above embodiments determines the region of interest in the endometrium using a first ultrasound wave, then emits ultrasound waves toward the region of interest in at least two emission directions, and receives the echoes of the ultrasound waves to obtain at least two sets of echo signals; based on each set of echo signals, the peristaltic motion component of the endometrium in the region of interest in the emission direction corresponding to that set of echo signals is calculated, thereby obtaining peristaltic motion components in multiple directions; the peristaltic parameters of the endometrium are determined based on the peristaltic motion components corresponding to multiple directions, thereby improving the accuracy of the peristaltic parameters.

[0146] In some embodiments, the method for detecting the peristaltic parameters of the endometrium described in the above embodiments can be used as a reference, or the peristaltic parameters of other peristaltic targets, such as the intestines, stomach, or other tissues, can be detected.

[0147] For example, embodiments of this application also provide another method for detecting peristaltic parameters, the detection method including:

[0148] The process involves: transmitting a first ultrasonic wave toward a wriggling target and receiving the echo of the first ultrasonic wave to obtain an ultrasonic echo signal; obtaining an ultrasonic image of the wriggling target based on the ultrasonic echo signal of the first ultrasonic wave; determining a region of interest based on the ultrasonic image; transmitting a second ultrasonic wave toward the region of interest in at least two transmission directions and receiving the echo of the second ultrasonic wave to obtain at least two sets of echo signals, wherein each set of echo signals corresponds to each transmission direction and includes echo signals at least two time points; calculating the wriggling motion component of the wriggling target in the region of interest in the transmission direction corresponding to each set of echo signals based on each set of echo signals, thereby obtaining at least two wriggling motion components; and determining the wriggling parameters of the wriggling target based on the at least two wriggling motion components.

[0149] In some embodiments, the peristaltic parameters of a peristaltic target can be characterized based on peristaltic motion components in multiple directions.

[0150] For example, embodiments of this application also provide another method for detecting peristaltic parameters, the detection method including:

[0151] The process involves transmitting a first ultrasonic wave toward a wriggling target and receiving the echo of the first ultrasonic wave to obtain an ultrasonic echo signal; obtaining an ultrasonic image of the wriggling target based on the ultrasonic echo signal of the first ultrasonic wave; determining a region of interest based on the ultrasonic image; transmitting a second ultrasonic wave toward the region of interest in at least two transmission directions and receiving the echo of the second ultrasonic wave to obtain at least two sets of echo signals, wherein each set of echo signals corresponds to each transmission direction and includes echo signals at least two time points; and calculating the wriggling motion component of the wriggling target in the region of interest in the transmission direction corresponding to each set of echo signals based on each set of echo signals.

[0152] In some embodiments, the peristaltic parameters of a peristaltic target, such as the endometrium, can be characterized based on peristaltic motion components in multiple directions.

[0153] For example, embodiments of this application also provide another method for detecting peristaltic parameters, the detection method including:

[0154] The process involves emitting a first ultrasound wave towards the endometrium and receiving the echo of the first ultrasound wave to obtain an ultrasound echo signal; obtaining an ultrasound image of the endometrium based on the ultrasound echo signal of the first ultrasound wave; determining a region of interest based on the ultrasound image; emitting a second ultrasound wave towards the region of interest in at least two emission directions and receiving the echo of the second ultrasound wave to obtain at least two sets of echo signals, wherein each set of echo signals corresponds to each emission direction and includes echo signals at at least two time points; and calculating the peristaltic motion component of the endometrium within the region of interest in the emission direction corresponding to each set of echo signals based on each set of echo signals.

[0155] Please see Figure 13 , Figure 13 This is a schematic flowchart illustrating another method for detecting peristaltic parameters provided in an embodiment of this application. Figure 13 As shown, the method for detecting the peristalsis parameter specifically includes steps S201 to S203.

[0156] S201. Emit ultrasound waves to the endometrium in at least two transmission directions and receive the echoes of the ultrasound waves to obtain at least two sets of echo signals.

[0157] Each set of echo signals corresponds to each of the transmission directions and includes echo signals at at least two times.

[0158] Specifically, the probe is controlled to emit ultrasound waves into the endometrium in at least two emission directions, and the probe is controlled to receive the echoes of the ultrasound waves, resulting in at least two sets of echo signals. Each set of echo signals corresponds to each emission direction at different times, and each set of echo signals includes echo signals from multiple times.

[0159] S202. Calculate the peristaltic motion component of the endometrium in the emission direction corresponding to each set of echo signals, thereby obtaining at least two peristaltic motion components.

[0160] Each peristaltic motion component of the endometrium is calculated based on each set of echo signals. Each peristaltic motion component corresponds to the emission direction of each set of echo signals and includes echo signals at at least two time points. The peristaltic motion component includes at least one of a peristaltic displacement component and a peristaltic velocity component.

[0161] S203. Determine the peristaltic parameters of the endometrium based on the at least two peristaltic motion components.

[0162] Specifically, multiple peristaltic motion components are synthesized to determine the motion vector corresponding to the endometrium; and the peristaltic parameters corresponding to the endometrium are determined based on the motion vector. For example, multiple peristaltic velocity components are synthesized into a peristaltic velocity vector, and the magnitude and direction of the endometrial motion velocity are determined based on this velocity vector. The magnitude and direction of the motion velocity are the peristaltic parameters of the endometrium.

[0163] For example, the peristaltic parameters include at least one of the following: tissue strain caused by peristalsis, tissue strain rate caused by peristalsis, acceleration of peristaltic movement, amplitude of peristalsis, frequency of peristalsis, total significant peristaltic movement time within a preset duration, propagation direction of peristaltic movement, propagation speed of peristaltic movement, range of peristaltic movement, degree of disorder of peristaltic movement, degree of non-uniformity of peristaltic amplitude, degree of non-uniformity of peristaltic direction, and distribution of peristaltic movement in the endometrium.

[0164] In one embodiment, peristalsis detection and ultrasound imaging can share the same ultrasound sequence; that is, the ultrasound echo signals used for peristalsis parameter detection can also be used to generate ultrasound images, such as ultrasound B-images. In one embodiment, the endometrium can be imaged based on spatial composite technology, using at least two sets of echo signals, with each set containing at least one moment, to obtain an image of the endometrium. Specifically, based on at least two sets of echo signals, with each set containing at least one moment—that is, extracting the echo signal corresponding to at least one moment for each emission direction—a spatial composite B-image is generated using spatial composite technology. This spatial composite B-image can eliminate artifacts, resulting in a more detailed B-image.

[0165] In another embodiment where peristalsis detection and ultrasound imaging share an ultrasound sequence, the endometrium can be imaged based on the echo signal at at least one moment in a set of echoes to obtain an image of the endometrium. In this embodiment, the endometrium can be imaged based on the echo signal at any moment in any set of echoes, i.e., the echo signal at any moment in any direction, to obtain an ultrasound image of the endometrium, such as a B-mode ultrasound image.

[0166] After obtaining the image of the endometrium, the image can be displayed for the user to observe.

[0167] In some embodiments, after determining the peristaltic parameters of the endometrium, these parameters can also be displayed. Specifically, the peristaltic parameters can be displayed in the imaging image so that the user can observe and make accurate judgments about the movement of the endometrium based on the imaging image and the peristaltic parameters.

[0168] It should be noted that the peristalsis parameter may include at least one statistic of the peristalsis motion component or at least one statistic of the motion vector synthesized from the peristalsis motion component.

[0169] The detection method disclosed in the above embodiments involves emitting ultrasound waves into the endometrium in at least two emission directions and receiving the echoes of the ultrasound waves in a receiving direction in the same direction as the emission directions to obtain at least two sets of echo signals; imaging the endometrium based on the echo signals; calculating the peristaltic motion components corresponding to the endometrium based on each set of echo signals to obtain peristaltic motion components in multiple directions; determining the peristaltic parameters of the endometrium based on the peristaltic motion components corresponding to the multiple directions; and displaying the ultrasound image and peristaltic parameters. This method improves the accuracy of the peristaltic parameters and facilitates user observation to make an accurate judgment on the movement of the endometrium.

Instead, the obtained peristaltic motion components or peristaltic motion vectors can be directly displayed. That is, the obtained peristaltic motion components or peristaltic motion vectors can be presented to the user in various suitable ways. For example, in one embodiment, the magnitude and / or direction of the peristaltic motion components or peristaltic motion vectors can be displayed; in another embodiment, a graph showing the changes of the peristaltic motion components or peristaltic motion vectors over time can also be displayed; in yet another embodiment, the peristaltic motion components or peristaltic motion vectors can be mapped to different colors according to their magnitude and / or direction and / or location and / or other properties to obtain a color mapping map, and the color mapping map can be displayed; and so on.
