The invention will be described in further detail below with reference to the drawings by means of specific embodiments. Wherein like elements in different embodiments are numbered alike in association. In the following embodiments, numerous specific details are set forth in order to provide a better understanding of the present application. However, one skilled in the art will readily recognize that some of the features may be omitted, or replaced by other elements, materials, or methods in different situations. In some instances, some operations associated with the present application have not been shown or described in the specification to avoid obscuring the core portions of the present application, and may not be necessary for a person skilled in the art to describe in detail the relevant operations based on the description herein and the general knowledge of one skilled in the art.
Furthermore, the described features, operations, or characteristics of the description may be combined in any suitable manner in various embodiments. Also, various steps or acts in the method descriptions may be interchanged or modified in a manner apparent to those of ordinary skill in the art. Thus, the various orders in the description and drawings are for clarity of description of only certain embodiments, and are not meant to be required orders unless otherwise indicated.
The numbering of the components itself, e.g. "first", "second", etc., is used herein merely to distinguish between the described objects and does not have any sequential or technical meaning. The terms "coupled" and "connected," as used herein, are intended to encompass both direct and indirect coupling (coupling), unless otherwise indicated.
As shown in fig. 1, the ultrasonic imaging apparatus provided by the present invention includes a probe (i.e., an ultrasonic probe) 10, a transmitting circuit 30, a receiving circuit 40, a processor 20, a man-machine interaction device 70, and a memory 80.
The ultrasound probe 10 includes a transducer (not shown in the figure) composed of a plurality of array elements arranged in an array. The array element is used for transmitting ultrasonic waves according to the excitation electric signals or converting received ultrasonic waves into electric signals. Each array element can thus be used to achieve a mutual conversion of the electrical pulse signal and the ultrasound wave, so as to achieve an ultrasound wave transmission to the biological tissue of the target object, and also to receive an echo wave of the ultrasound wave reflected back by the tissue.
The transmitting circuit 30 is used for exciting the ultrasonic probe 10 to transmit ultrasonic waves to a target object according to the control of the processor 20.
The receiving circuit 40 is configured to receive an ultrasonic echo returned from a target object through the ultrasonic probe 10 to obtain an ultrasonic echo signal, and may also process the ultrasonic echo signal. The receive circuitry 40 may include one or more amplifiers, analog-to-digital converters (ADCs), and the like.
The man-machine interaction device 70 is used for man-machine interaction, such as outputting visual information and receiving user input. The input of the user can be received by a keyboard, an operation button, a mouse, a track ball, a touch pad and the like, and a touch screen integrated with a display can also be adopted; the output visual information can be a display.
The memory 80 is used to store various types of data.
The ultrasound imaging device may also include a beam synthesis module 50 and an IQ demodulation module 60.
The beam forming module 50 is in signal connection with the receiving circuit 40, and is configured to perform corresponding beam forming processes such as delay and weighted summation on the echo signals, and because distances from the ultrasonic receiving points in the tissue to be measured to the receiving array elements are different, channel data of the same receiving point output by different receiving array elements have delay differences, delay processing is required to be performed, phases are aligned, and different channel data of the same receiving point are weighted and summed, so as to obtain beamformed ultrasonic image data, and the ultrasonic image data output by the beam forming module 50 is also referred to as radio frequency data (RF data). The beam forming module 50 outputs the radio frequency data to the IQ demodulation module 60. In some embodiments, the beam forming module 50 may also output the rf data to the memory 80 for buffering or saving, or directly output the rf data to the processor 20 for image processing.
The beam forming module 50 may perform the above functions in hardware, firmware, or software. The beam forming module 50 may be integrated in the processor 20 or may be separately provided, which is not limited by the present invention.
The IQ demodulation module 60 removes the signal carrier by IQ demodulation, extracts the tissue structure information contained in the signal, and performs filtering to remove noise, and the signal obtained at this time is referred to as a baseband signal (IQ data pair). The IQ demodulation module 60 outputs IQ data pairs to the processor 20 for image processing. In some embodiments, the IQ demodulation module 60 also outputs IQ data pairs to the memory 80 for buffering or saving so that the processor 20 reads the data from the memory 80 for subsequent image processing.
The IQ demodulation module 60 may also perform the above functions in hardware, firmware, or software. Similarly, the IQ demodulation module 60 may be integrated in the processor 20 or may be separately provided, which is not limited by the present invention.
The processor 20 is configured to be a central controller Circuit (CPU), one or more microprocessors, graphics controller circuits (GPU) or any other electronic component capable of processing input data according to specific logic instructions, which may perform control of peripheral electronic components, or data reading and/or saving of memory 80, according to the input instructions or predetermined instructions, and may also perform processing of the input data by executing programs in the memory 80, such as one or more processing operations on the acquired ultrasound data according to one or more modes of operation, including but not limited to adjusting or defining the form of ultrasound emitted by the ultrasound probe 10, generating various image frames for display by a display of a subsequent human-machine interaction device 70, or adjusting or defining the content and form displayed on the display, or adjusting one or more image display settings (e.g., ultrasound images, interface components, locating regions of interest) displayed on the display.
The acquired ultrasound data may be processed by the processor 20 in real time during scanning as the echo signals are received, or may be temporarily stored on the memory 80 and processed in near real time in an on-line or off-line operation.
In this embodiment, the processor 20 controls the operation of the transmitting circuit 30 and the receiving circuit 40, for example, controls the transmitting circuit 30 and the receiving circuit 40 to operate alternately or simultaneously. The processor 20 may also determine an appropriate operation mode according to a user's selection or a program setting, form a transmission sequence corresponding to the current operation mode, and send the transmission sequence to the transmission circuit 30, so that the transmission circuit 30 controls the ultrasonic probe 10 to transmit ultrasonic waves using the appropriate transmission sequence.
The processor 20 is also operative to process the ultrasound data to generate a gray scale image of the signal intensity variations over the scan range reflecting the anatomy inside the tissue, referred to as the B image. The processor 20 may output the B-image to a display of the human interaction device 70 for display.
The invention mainly improves the method for checking the achilles tendon of the target object so as to improve the degree of automation of checking, thereby improving the checking efficiency. Therefore, the processor 20 is further configured to acquire first ultrasonic image data of the left achilles tendon of the target object and second ultrasonic image data of the corresponding right achilles tendon; wherein, the first ultrasonic image data is obtained by scanning the left leg achilles tendon of the target object by the probe 10, and the first ultrasonic image data comprises ultrasonic images of cross sections of a plurality of positions of the left leg achilles tendon; second ultrasound image data is obtained from the probe 10 scanning the right leg achilles tendon of the target object, the second ultrasound image data including ultrasound images of cross-sections of the right leg achilles tendon at a plurality of locations. The processor 20 is further configured to match the first ultrasound image data with the second ultrasound image data to obtain ultrasound image sets at a plurality of positions; wherein the ultrasound image set for one location comprises: a cross-sectional ultrasound image of the achilles tendon of the left leg at the location and a cross-sectional ultrasound image of the achilles tendon of the right leg at the location. Therefore, the user only needs to sweep the left and right achilles tendons of the target object, the ultrasonic imaging equipment can automatically match the ultrasonic images of the cross section of the same position of the left and right achilles tendons, manual identification of the user is not needed, the workload of the user is saved, and the efficiency of achilles tendon examination is improved.
The method of examination of the achilles tendon by the ultrasound imaging apparatus may also be more than this, as will be described in detail below by way of some embodiments.
In the embodiment shown in fig. 2 and 3, the method for inspecting the achilles tendon of the target object by the ultrasonic imaging apparatus specifically includes the following steps:
step 1, the processor 20 acquires first ultrasonic image data of the left achilles tendon of the target object and second ultrasonic image data of the corresponding right achilles tendon. The ultrasound image data may be obtained from other devices, or may be obtained by scanning the achilles tendon of the target object with the present ultrasound imaging device, the latter being illustrated as an example in this embodiment. In this embodiment, the first ultrasound image data and the second ultrasound image data are obtained by scanning the corresponding achilles tendon by the probe 10 according to a preset scanning method; the first ultrasound image data and the second ultrasound image data each include ultrasound images of cross-sections of a plurality of locations of the achilles tendon. The left and right achilles tendons adopt the same scanning technique, which is beneficial to the subsequent data matching. The target object may be a human or an animal, and in this embodiment, the target object is exemplified as a horse, and the ultrasonic imaging device may be a veterinary ultrasonic imaging device.
Specifically, the input device is provided with an intelligent achilles key, which may be a physical key or a virtual key on the display interface (e.g., the "Smart Tendon" key shown in fig. 9). The user triggers (e.g., presses, touches, or cursor clicks, etc.) an intelligent achilles key, which then issues an instruction to initiate an achilles examination. The processor 20 receives an instruction for starting an achilles tendon examination through the input device, and in response to the instruction, enters an achilles tendon examination mode. And the user presses the intelligent achilles tendon key again, and then the achilles tendon inspection mode is exited.
The input device is also provided with a left leg key (the "Lt Foot" key shown in fig. 9) and a right leg key (the "Rt Foot" key shown in fig. 9). The left leg key is used for determining ultrasonic image data obtained by scanning as ultrasonic image data (namely first ultrasonic image data) of the achilles tendon of the left leg, and the right leg key is used for determining ultrasonic image data obtained by scanning as ultrasonic image data (namely second ultrasonic image data) of the achilles tendon of the right leg.
After the achilles tendon examination mode is entered, the left and right leg achilles tendons can be scanned. The user can trigger the left leg key, after the left leg key is triggered, the image is thawed, the user operates the probe to sweep the image according to a preset image sweeping method, and the processor 20 correspondingly scans the achilles tendon of the left leg of the target object through the probe, namely, transmits ultrasonic waves, receives ultrasonic echo signals and processes the ultrasonic echo signals, obtains ultrasonic image data (such as buffering one or more frames of ultrasonic images) and freezes the ultrasonic image data. The user operates the input device to issue a map storing instruction, and after receiving the map storing instruction through the input device, the processor 20 stores the scanned first ultrasonic image data of the left leg achilles tendon.
Similarly, the user may trigger the right leg key, after the right leg key is triggered, defrost the image, the user operates the probe to scan the image according to the preset scanning method, and the processor 20 scans the achilles tendon of the right leg of the target object through the probe correspondingly, that is, transmits ultrasonic waves, receives ultrasonic echo signals and processes the ultrasonic echo signals, obtains ultrasonic image data (such as buffering one or more frames of ultrasonic images) and freezes the ultrasonic image data. The user operates the input device to issue a map storing instruction, and the processor 20 stores the scanned second ultrasonic image data of the achilles tendon of the right leg after receiving the map storing instruction through the input device. The first ultrasound image data and the second ultrasound image data each include ultrasound images of cross-sections of a plurality of locations of the achilles tendon.
The preset pattern scanning method can be multiple, and subsequent matching is facilitated. Two kinds of them will be described below.
The method for scanning the picture comprises the following steps: the probe is moved along one end of the achilles tendon to the other for continuous scanning. For example, the user applies the probe to one end of the achilles tendon, operates the input device of the man-machine interaction device 70 to enable the processor 20 to activate the probe 10, the probe 10 starts to emit ultrasonic waves and receive ultrasonic echoes, and the user moves the probe 10 to the other end along one end of the achilles tendon, so that uniform speed movement can be adopted, and subsequent matching is facilitated; during the movement of the probe 10, the processor 20 processes the ultrasonic echo data in real time, generates a real-time ultrasonic image and displays the real-time ultrasonic image through the display of the man-machine interaction device 70; after the probe 10 is moved to the other end of the achilles tendon, the user operates the input device to cause the processor 20 to freeze the image. The process of activating the probe 10 to freeze the image is a sweep. The scanning technique in this example covers the entire achilles tendon by scanning once, and is continuous, and the obtained ultrasonic image data are continuous in time. The continuous ultrasound image data is data obtained by performing beam forming processing on ultrasound echoes during a continuous scan (during the period when the probe moves from one end to the other end of the achilles tendon), for example, may be a section of radio frequency data, a section of IQ data pair, or a section of ultrasound video, which is described as an example in this embodiment, that is, the continuous scan obtains a section of ultrasound video including continuous multi-frame ultrasound images. With the present scanning technique, the veterinarian scans the achilles tendon at a constant speed along the achilles tendon with the probe at one side, and the processor 20 recognizes, calculates, and stores the ultrasonic image data (e.g., the first ultrasonic image data) of the entire achilles tendon, and performs the same scanning examination on the achilles tendon at the other side to obtain the ultrasonic image data (e.g., the second ultrasonic image data) of the other achilles tendon. The ultrasonic image data of the achilles tendon of the left and right legs is acquired for the purpose of judging the injury, recovery, etc. of the achilles tendon by comparing the ultrasonic images of the same positions of the left and right legs. The left and right legs may be left and right front legs or left and right rear legs, which are comparable.
Another method of scanning is: the probe scans the plurality of preset achilles tendon positions according to a preset sequence (such as from top to bottom or from bottom to top). The exemplary previous scan is a continuous scan, and the exemplary scan is a multi-point scan or a multiple scan. For example, the plurality of preset achilles positions include two ends of the achilles, the user holds the probe against one end of the achilles, the user operates the input device of the human-computer interaction device 70 to enable the processor 20 to activate the probe 10, the probe 10 starts to emit ultrasonic waves and receive ultrasonic echoes to obtain ultrasonic image data of the ends of the achilles, and the user operates the input device to enable the processor 20 to freeze the image. The probe 10 is then moved to the next achilles tendon position (e.g., the probe is moved down 2cm or up 2 cm), the probe 10 is continuously activated, ultrasound image data of the achilles tendon position is obtained, and the image is frozen. And the subsequent scanning of the achilles tendon position is similar to the previous scanning until all preset achilles tendon positions are scanned, and the ultrasonic image data of all preset achilles tendon positions form first ultrasonic image data or second ultrasonic image data. Likewise, in this embodiment, the type of the ultrasound image data may be radio frequency data, IQ data pairs, or ultrasound images, which is described in this embodiment as an example, that is, the ultrasound image data in this embodiment includes ultrasound images of respective preset achilles tendon positions. Each pair of preset achilles tendon positions is scanned and the processor 20 generates an ultrasound image from the ultrasound echoes and displays it on a display. With the present scanning technique, a veterinarian scans a plurality of preset achilles tendon positions along the achilles tendon with a probe at one side of the horse leg, and the processor 20 recognizes, calculates, and stores the ultrasound image data (e.g., obtains the first ultrasound image data) of each achilles tendon position, and performs the same scanning examination on the achilles tendon at the other side of the horse leg to obtain the ultrasound image data (e.g., obtains the second ultrasound image data) of the other achilles tendon.
After the first ultrasound image data and the second ultrasound image data are obtained, the subsequent steps may be automatically performed, or may be performed under the triggering of the user, which is described as an example in this embodiment. The input device is further provided with an automatic calculation key, and the user activates the automatic calculation key, and then issues an instruction for starting automatic calculation, and the processor 20 receives the instruction for starting automatic calculation through the input device, and in response to the instruction, performs the subsequent steps.
Step 2, the processor 20 matches the first ultrasonic image data with the second ultrasonic image data to obtain ultrasonic image groups of a plurality of positions; wherein the ultrasound image set for one location comprises: a cross-sectional ultrasound image of the achilles tendon of the left leg at the location and a cross-sectional ultrasound image of the achilles tendon of the right leg at the location. There are many matching methods, and the ultrasonic images of the same achilles tendon position of the left and right legs can be matched. Several matching methods are illustrated below.
The first matching method has relevance with the scanning method of the first step, namely, the preset scanning method is required to be: the probe 10 is moved at a constant speed along one end of the achilles tendon to the other end for continuous scanning. As shown in fig. 4, the matching method includes the following steps:
Step 21, the processor 20 determines positions of achilles tendons corresponding to the plurality of ultrasound images according to a time sequence of the plurality of ultrasound images in the first ultrasound image data. The processor 20 determines the locations of the achilles tendons corresponding to the plurality of ultrasound images according to the temporal order of the plurality of ultrasound images in the second ultrasound image data. Since the ultrasound images (the first obtained ultrasound image and the last obtained ultrasound image) of the two ends of the achilles tendon are known and the probe 10 is moved at a constant speed while scanning continuously, the time of each ultrasound image of the ultrasound image data is in one-to-one correspondence with the achilles tendon position, and the processor 20 may correlate the time when generating the ultrasound image or may correspond the time with the number of frames, for example, assuming that the ultrasound image data has 1000 frames of ultrasound images in total, the frames of the 1000 frames of images are ordered by the generation time, the achilles tendon position corresponding to the 500 th ultrasound image is the middle of the achilles tendon, and the 333 rd ultrasound image corresponds to the 1/3 position of the achilles tendon. The number of frames of these 1000 frames of images is equally divided, that is, the achilles tendon is equally divided, so that the achilles tendon position corresponding to each ultrasound image can be obtained.
Step 22, the processor 20 matches the ultrasound image at the same location in the first ultrasound image data with the ultrasound image at the same location in the second ultrasound image data to obtain an ultrasound image set. For example, the processor 20 sequentially samples the first ultrasound image data in a preset sampling manner (such as equally sampling) to obtain a plurality of ultrasound images, and sequentially samples the second ultrasound image data in a preset sampling manner to obtain a plurality of ultrasound images; and matching the plurality of ultrasonic images obtained by sequentially sampling the first ultrasonic image data with the plurality of ultrasonic images obtained by sequentially sampling the second ultrasonic image data one by one to obtain ultrasonic image groups at a plurality of positions. For example, the ultrasonic images of the top ends of the achilles tendon of the left and right legs are matched to the ultrasonic image group of the top end of the achilles tendon, the ultrasonic image of the 1/3 position on the achilles tendon of the left and right legs is matched to the ultrasonic image group of the 1/3 position on the achilles tendon, the ultrasonic image of the middle position of the achilles tendon of the left and right legs is matched to the ultrasonic image group of the middle position of the achilles tendon, the ultrasonic image of the 1/3 position under the achilles tendon of the left and right legs is matched to the ultrasonic image group of the bottom end of the achilles tendon, and the like.
By adopting the matching method and matching with the picture sweeping method of the user, the ultrasonic images of the left leg and the right leg at the same position can be conveniently and rapidly matched.
The second adaptation method requires the aid of other means, for example, a sensor for detecting the height of the probe, such as a laser distance measuring sensor, etc., being provided on the probe 10. The first ultrasonic image data are obtained by scanning the left leg achilles tendon of the horse under the triggering of a plurality of preset probe heights by the probe 10 respectively; the second ultrasonic image data are obtained by scanning the right leg achilles tendon of the horse by the probe 10 under the triggering of a plurality of preset probe heights respectively. In other words, the scanning in step 1 may be triggered by a sensor, and the veterinary hand-held probe is moved along one end of the achilles tendon to the other end, during which the sensor detects the probe height, and when the probe height is at a preset probe height, the probe is automatically activated, and then the scanning may be automatically stored, so as to obtain an ultrasonic image of the position of the achilles tendon corresponding to the probe height. Therefore, the veterinarian only needs to move the probe from one end of the achilles tendon to the other end, the operation is very simple, the automation degree is high, and the efficiency is improved. Of course, the sensor may also only prompt the veterinarian after the preset probe height, with the veterinarian manually operating to activate the probe, deposit the map, etc.
The scanning of the achilles tendon is performed by scanning the cross section of the achilles tendon to obtain an ultrasonic image. Since the ultrasound images are acquired with a known probe height trigger, the height of the cross section to which each ultrasound image belongs in the ultrasound image data is known. Further, the processor 20 matches the ultrasound images of the same height cross section in the first ultrasound image data and the second ultrasound image data to obtain an ultrasound image group.
The third adaptation method likewise requires the use of other means, for example, sensors for detecting the height of the probe, such as laser distance measuring sensors, etc., on the probe 10. As shown in fig. 5, the matching method includes the following steps:
step 21', the processor 20 acquires first height data detected by the sensor on the probe 10 in the process of scanning the left leg achilles tendon of the horse to obtain first ultrasonic image data; taking the height acquired by the sensor at the same moment as the height of the cross section of the ultrasonic image acquired by the probe at the moment; in other words, the processor 20 generates an ultrasonic image according to the ultrasonic echo data, and correlates the height detected by the sensor at the same time to the ultrasonic image, where the height correlated to the ultrasonic image is the height where the probe scans to obtain the ultrasonic image, that is, the height of the achilles tendon cross section to which the ultrasonic image belongs. The processor 20 acquires second height data detected by the sensor on the probe 10 in the process of scanning the achilles tendon of the right leg of the horse to obtain second ultrasonic image data; and taking the height acquired by the sensor at the same moment as the height of the cross section of the ultrasonic image acquired by the probe at the moment.
Step 22', processor 20 matches the ultrasound images of the same height cross section in the first ultrasound image data with the ultrasound images of the same height in the second ultrasound image data to obtain an ultrasound image set. This approach is more data-handling than the second approach. The height sensor is used for determining the position (height) of the achilles tendon corresponding to the ultrasonic image, so that the accuracy is higher.
After obtaining an ultrasound image set of multiple achilles tendon positions, there are several ways of processing, several of which are described below.
One is of the "automatic" type, as shown in fig. 2, the method further comprises the steps of:
step 3, the processor 20 acquires the achilles tendon region in the two ultrasound images of the ultrasound image group at the same position.
The processor 20 may automatically identify the achilles tendon region in the two ultrasound images of the co-located ultrasound image set. For example, the processor 20 inputs two ultrasound images of the co-located ultrasound image set into a pre-trained deep learning model or machine learning model, respectively, to obtain achilles tendon regions in the two ultrasound images of the ultrasound image set, although image recognition techniques may be used to determine the achilles tendon regions in some embodiments.
The processor 20 may display the ultrasound image group at the same position via the display, may display only the ultrasound image group at one position, or may display the ultrasound image groups at a plurality of positions. The left and right properties of the ultrasound images may also be marked when two ultrasound images of the ultrasound image set are displayed (i.e., whether the ultrasound images are left or right leg, as shown in LF and RF of fig. 10); the achilles tendon region is marked on the ultrasound images of the ultrasound image set by the veterinarian. The processor 20 receives, via the input device, the marked achilles tendon region in one of the ultrasound images of the set of ultrasound images of the user at the same location, and determines it as the achilles tendon region of the ultrasound image; likewise, the achilles tendon region marked by the user in another ultrasound image is received through the input device and determined as the achilles tendon region of the ultrasound image.
Whether the achilles tendon area is automatically identified by the processor 20 or manually marked by the user, it can be further processed to facilitate the calculation of subsequent amounts of discrepancy. For example, as shown in fig. 6, the processor 20 takes one of the longest line segments at any two points on the boundary of the achilles tendon region (indicated by a broken line in the figure) as a major axis a, takes a line segment connecting the two points on the boundary of the achilles tendon region and overlapping with a perpendicular to the major axis as a minor axis b, and takes an ellipse (indicated by a solid line in the figure) defined by the major axis a and the minor axis b as a final achilles tendon region.
In some embodiments, the user may also adjust whether the achilles tendon region is automatically identified, manually marked by the user, or further processed into an elliptical achilles tendon region (the final achilles tendon region described above). That is, the processor marks the boundary of the achilles tendon region, in other words, the boundary of the achilles tendon region is provided with a mark (shown by a broken line in fig. 10) in the ultrasound image group displayed on the display. The processor 20 receives an operation of adjusting the boundary of the achilles tendon region by the user through the input device, adjusts the boundary of the achilles tendon region according to the operation, and updates the display; for example, the input device is provided with an edit key for turning on adjustment of the achilles tendon region marker; the processor 20 is also configured to: after the edit key is triggered, receiving an operation of adjusting the boundary mark of the achilles tendon region by a user through an input device, adjusting the boundary of the achilles tendon region according to the operation, updating the display, and calculating by using the latest achilles tendon region in the follow-up step, such as updating the difference according to the adjusted boundary of the achilles tendon region.
Step 4, the processor 20 obtains and outputs a difference value for representing the size difference of the two achilles tendon regions according to the achilles tendon regions of the two ultrasonic images in the ultrasonic image group at the same position. Healthy Ma Genjian, the difference between the achilles tendon areas at the same height on the left and right sides is small, and if the difference is too large, it indicates that there is injury or no recovery of the achilles tendon on one side. The difference amount may include at least one of a difference in the areas of the two achilles tendon regions, a normalized difference in the areas of the two achilles tendon regions, a difference in the circumferences of the two achilles tendon regions, and a normalized difference in the circumferences of the two achilles tendon regions. If the latest achilles tendon region is the above-described elliptical achilles tendon region, the processor 20 calculates the achilles tendon region area, the achilles tendon region perimeter, and the like from the long and short axes of the ellipse, and further calculates the above-described difference. If the most recent achilles area is not a standard ellipse, the processor 20 may count the total number of pixels in the achilles area, multiply the actual area represented by each pixel to obtain the achilles area, count the total number of pixels at the boundary of the achilles area, multiply the length or width of the corresponding pixel to obtain the perimeter of the achilles area, and calculate the difference. Of course, it is also possible to first superimpose the two achilles tendon regions to obtain a difference region, and to obtain an area difference and/or a perimeter difference according to the difference region. The normalized difference of the areas of the two achilles tendon regions can be obtained by the existing method, for example, the normalized difference is: the absolute value of the difference in the areas of the two achilles tendon regions divided by the area of the large achilles tendon region, i.e., the normalized difference in the areas of the two achilles tendon regions is the stenosis ratio of the areas of the two achilles tendon regions. Similarly, the normalized difference of the circumferences of the two achilles tendon regions can be obtained by the existing method, for example, the normalized difference is: the absolute value of the difference in the circumferences of the two achilles tendon regions divided by the circumference of the large achilles tendon region.
The processor 20 outputs the discrepancy gauge, for example, via a display, and the veterinarian sees the discrepancy gauge to understand the discrepancy between the left and right achilles tendons of the affected leg, and thus to learn about the injury or recovery of the affected leg. When the difference is displayed, the corresponding achilles tendon position may also be displayed. If the difference is the difference of the areas of the two achilles tendon regions or the normalized difference of the areas of the two achilles tendon regions, the areas of the two achilles tendon regions may also be displayed when the difference is displayed. If the difference is the difference between the circumferences of the two achilles tendon regions or the normalized difference between the circumferences of the two achilles tendon regions, the circumferences of the two achilles tendon regions may also be displayed when the difference is displayed.
The steps are matched with a plurality of ultrasonic image groups, and a plurality of corresponding achilles tendon positions and difference amounts thereof are displayed for veterinary reference. For example, a schematic diagram of the horse leg is displayed on a display interface of the display, and the achilles tendon position and the corresponding difference amount thereof are marked on the schematic diagram. Different achilles tendon positions and their difference amounts may be displayed simultaneously or separately. In this embodiment, as shown in fig. 10, the ultrasonic images of the left and right leg achilles tendons of the ultrasonic image group at the same position are displayed together with the area or circumference of the achilles tendon region on the ultrasonic image and the corresponding difference amount. The input device is also provided with a plurality of position selection keys, one corresponding to each achilles tendon position. Taking 7 position selection keys 1A-3C in FIG. 9 as an example, 1A and 3C correspond to the two ends of the Achilles tendon, and 1B-3B correspond to the positions of 5 equally divided points of the Achilles tendon. The processor 20 displays the ultrasound image group corresponding to the achilles tendon position of the currently activated position selection key and the difference amount of the ultrasound image group on the display interface of the display according to the currently activated position selection key. That is, it is very convenient to click on which position selection key in order to see which position of the achilles tendon the ultrasound image or the difference amount.
The input device is also provided with an overview key (e.g. the "All" key in fig. 9). After the overview key is triggered, the processor 20 displays the ultrasound image groups at a plurality of preset positions and the difference amounts of the ultrasound image groups, that is, displays the ultrasound image groups at all preset positions and the difference amounts thereof, on the display interface of the display.
The input device is also provided with a reacquire key (e.g. the "reacquire" key in fig. 9). The re-acquisition key is used for starting the function of re-acquiring the ultrasonic image data. If the first ultrasonic image data or the second ultrasonic image data does not meet the requirement, the user triggers the reacquiring key and the left leg key to reacquire the first ultrasonic image data, and the user triggers the reacquiring key and the right leg key to reacquire the second ultrasonic image data. Specifically, after the reacquiring key is triggered, if the current left leg key is also in the triggered state, the processor 20 rechecks the left leg achilles tendon of the target object through the probe; after receiving the image storage instruction through the input device, storing the first ultrasonic image data obtained by rescanning and deleting the original first ultrasonic image data, wherein the specific process is the same as that of the first ultrasonic image data obtained for the first time, and the description is given. After the ultrasound image data is re-acquired, the amount of difference can be recalculated. The input device is also provided with a recalculate key (e.g. the "recalculate" key in fig. 9). After the recalculation key is triggered, the processor 20 updates the ultrasound image set and the difference thereof for displaying at least one position on the display interface of the display according to the first ultrasound image data and the original second ultrasound image data obtained by the rescanning.
After the reacquiring key is triggered, if the current right leg key is also in a triggering state, scanning the right leg achilles tendon of the target object again through the probe; after receiving the image storage instruction through the input device, saving the second ultrasonic image data obtained by rescanning and deleting the original second ultrasonic image data, wherein the specific process is the same as that of the first process for obtaining the second ultrasonic image data, and the description is given. After the recalculation key is triggered, the processor 20 updates the ultrasound image set and the amount of difference thereof for displaying at least one location on the display interface of the display based on the first ultrasound image data and the rescanned second ultrasound image data.
Currently, the examination of the achilles tendon of a horse is completely manual, and an ultrasonic imaging device only provides the function of scanning a graph to obtain an ultrasonic image. While the veterinarian would need to scan multiple locations of Ma Genjian to obtain an ultrasound image of its cross section, both legs would need to scan, taking a long time. The veterinarian can only squat between two legs or on the side of the horse generally, the longer the operation time is, the more dysphoria the horse is easy, and the greater the probability of being injured by the horse legs, but the ultrasonic imaging equipment provided by the invention only needs to concentrate on scanning a picture, even only needs to scan from one end of the achilles tendon to the other end, the operation time is very short, the follow-up automatic output result (difference) is very high, the automation degree is very high, namely, the examination efficiency of the horse achilles tendon is improved, and the safety of the veterinary work is also improved.
The invention also supports the examination of the achilles tendon of the four limbs, namely, the method shown in fig. 2 is carried out twice in succession, the difference of the positions of the achilles tendons of the front legs and the difference of the positions of the receding achilles tendons are obtained, the difference is displayed, and the efficiency is higher when a veterinarian examines the achilles tendon condition of Ma Sizhi once.
Processor 20 also stores the plurality of achilles tendon positions and their discrepancies in memory 80, providing a corresponding display interface for subsequent review by a veterinarian. For example, the input device is also provided with a history key that the veterinarian triggers to issue instructions for viewing the amount of history discrepancy. Processor 20, in response to instructions for viewing the historical variance, obtains the variance for different times of the same achilles tendon position of the current horse; and drawing a first difference curve according to the difference obtained in different periods of the same achilles tendon position, and outputting the first difference curve, and likewise, outputting the first difference curve to a display to display. The first difference curve reflects the variation of the difference obtained at different periods of the same achilles tendon position, so that a doctor can conveniently and comprehensively evaluate the recovery condition of the achilles tendon of the horse.
The input device is further provided with a current data key, and the processor 20 is further configured to draw a second difference curve from the differences of the different positions of the same achilles tendon after the current data key is triggered, and display the second difference curve through the display, where the second difference curve reflects the variation of the differences of the different positions of the same achilles tendon, and the second difference curve is used for a doctor to refer to.
The left leg key, the right leg key, the automatic calculation key, the recalculation key, the edit key, the position selection key, the overview key, the current data key, the history data key, and the like may be physical keys or virtual keys, and the latter is described as an example in this embodiment. In this embodiment, after the intelligent achilles tendon key is triggered, the display displays an operation interface, where the operation interface is shown in fig. 9, and the operation interface includes virtual keys such as the above-mentioned left leg key, right leg key, automatic calculation key, reacquire key, recalculate key, edit key, position selection key, overview key, current data key and history data key, and the user performs corresponding operations on the operation interface, so that the functions described in the above steps 2-4 can be executed. The man-machine interaction device may include a main display and a sub-display, the main display may display the ultrasonic image group and the difference thereof, as shown in fig. 10, and the sub-display may display the operation interface, so that man-machine interaction may be better performed.
The method shown in fig. 2, step 2, can be followed automatically by a discrepancy amount, although in some embodiments the discrepancy amount can be calculated or evaluated manually by a veterinarian. As shown in fig. 3, after step 2, a method for inspecting achilles tendon further includes the following steps:
Step 3', processor 20 outputs the co-located ultrasound image set. For example, the processor 20 outputs the co-located ultrasound image set to a display for display, and may also mark the left and right properties of the ultrasound image (i.e., whether the ultrasound image is a left leg or a right leg) when displaying two ultrasound images of the ultrasound image set. After the veterinarian sees the left leg ultrasonic image and the right leg ultrasonic image of the same achilles tendon position, the achilles tendon difference of the achilles tendon position can be measured, compared and calculated by himself, and therefore the achilles tendon condition of the affected leg is judged. Of course, the achilles tendon region may also be automatically identified and displayed by the ultrasonic imaging apparatus, see step 3 of the embodiment of fig. 2, which is not described herein.
While the above embodiments are mainly based on differences between the left and right legs, in some embodiments, a veterinarian may periodically perform ultrasonic examination on Ma Genjian to accumulate ultrasonic image data of achilles tendons in various periods, and the differences between the ultrasonic images of the same leg in different periods may be used as a basis for the judgment. As shown in fig. 7 and 8, the method comprises the following steps:
step 6, the processor 20 acquires third ultrasonic image data of the achilles tendon of the affected leg of the target object (for example, horse) and fourth ultrasonic image data detected by the affected leg during health; the third ultrasonic image data and the fourth ultrasonic image data are obtained by scanning the achilles tendon by the probe 10 according to a preset scanning method; the third ultrasound image data and the fourth ultrasound image data each include ultrasound images of cross-sections of a plurality of locations of the achilles tendon.
The preset pattern sweeping method can be various.
The method for scanning the picture comprises the following steps: the probe is moved along one end of the achilles tendon to the other for continuous scanning. For example, the user applies the probe to one end of the achilles tendon, operates the input device of the man-machine interaction device 70 to enable the processor 20 to activate the probe 10, the probe 10 starts to emit ultrasonic waves and receive ultrasonic echoes, and the user moves the probe 10 to the other end along one end of the achilles tendon, so that uniform speed movement can be adopted, and subsequent matching is facilitated; during the movement of the probe 10, the processor 20 processes the ultrasonic echo data in real time, generates a real-time ultrasonic image and displays the real-time ultrasonic image through the display of the man-machine interaction device 70; after the probe 10 is moved to the other end of the achilles tendon, the user operates the input device to cause the processor 20 to freeze the image. The process of activating the probe 10 to freeze the image is a sweep. The scanning technique in this example covers the entire achilles tendon by scanning once, and is continuous, and the obtained ultrasonic image data are continuous in time. The continuous ultrasound image data is data obtained by performing beam forming processing on ultrasound echoes during a continuous scan (during the period when the probe moves from one end to the other end of the achilles tendon), for example, may be a section of radio frequency data, a section of IQ data pair, or a section of ultrasound video, which is described as an example in this embodiment, that is, the continuous scan obtains a section of ultrasound video including continuous multi-frame ultrasound images. Using the present scanning technique, the veterinarian scans the horse leg on one side with a probe at a constant speed throughout the achilles tendon, and the processor 20 identifies, calculates, and stores the ultrasound image data (e.g., third ultrasound image data) of the entire achilles tendon.
Another method of scanning is: the probe scans the plurality of preset achilles tendon positions according to a preset sequence (such as from top to bottom or from bottom to top). The exemplary previous scan is a continuous scan, and the exemplary scan is a multi-point scan or a multiple scan. For example, the plurality of preset achilles positions include two ends of the achilles, the user holds the probe against one end of the achilles, the user operates the input device of the human-computer interaction device 70 to enable the processor 20 to activate the probe 10, the probe 10 starts to emit ultrasonic waves and receive ultrasonic echoes to obtain ultrasonic image data of the ends of the achilles, and the user operates the input device to enable the processor 20 to freeze the image. The probe 10 is then moved to the next achilles tendon position (e.g., the probe is moved down 2cm or up 2 cm), the probe 10 is continuously activated, ultrasound image data of the achilles tendon position is obtained, and the image is frozen. And the subsequent scanning of the achilles tendon position is similar to the previous scanning until all preset achilles tendon positions are scanned, and the ultrasonic image data of all preset achilles tendon positions form third ultrasonic image data or fourth ultrasonic image data. Likewise, in this embodiment, the type of the ultrasound image data may be radio frequency data, IQ data pairs, or ultrasound images, which is described in this embodiment as an example, that is, the ultrasound image data in this embodiment includes ultrasound images of respective preset achilles tendon positions. Each pair of preset achilles tendon positions is scanned and the processor 20 generates an ultrasound image from the ultrasound echoes and displays it on a display. With the present scanning technique, the veterinarian scans the positions of the plurality of preset achilles tendon with the probe along the achilles tendon from the beginning to the end at one side of the horse leg, and the processor 20 recognizes, calculates, and saves the ultrasound image data (e.g., obtains the third ultrasound image data) of each achilles tendon position.
The specific process is the same as the step 1 in the above embodiment, and will not be described herein.
Likewise, after the third ultrasound image data and the fourth ultrasound image data are obtained, the subsequent steps may be performed automatically or may be performed under the trigger of the user, for example, the processor 20 receives an instruction for starting the automatic calculation through the input device, and in response to the instruction, the subsequent steps 7, 8, and 9 are performed.
Step 7, the processor 20 matches the third ultrasonic image data with the fourth ultrasonic image data to obtain ultrasonic image groups at a plurality of positions; wherein the ultrasound image set for one location comprises: a cross-sectional ultrasound image of the current achilles tendon at the location, and a cross-sectional ultrasound image of the achilles tendon at the location while healthy.
Several matching methods are illustrated below.
The first matching method has relevance with the scanning method of the first step, namely, the preset scanning method is required to be: the probe 10 is moved at a constant speed along one end of the achilles tendon to the other end for continuous scanning. The matching method comprises the following steps:
processor 20 determines the locations of the achilles tendons corresponding to the plurality of ultrasound images in the third ultrasound image data based on the temporal order of the plurality of ultrasound images. Processor 20 determines the locations of the achilles tendons corresponding to the plurality of ultrasound images in the fourth ultrasound image data based on the temporal order of the plurality of ultrasound images. Since the ultrasound images (the first obtained ultrasound image and the last obtained ultrasound image) of the two ends of the achilles tendon are known and the probe 10 is moved at a constant speed while scanning continuously, the time of each ultrasound image of the ultrasound image data is in one-to-one correspondence with the achilles tendon position, and the processor 20 may correlate the time when generating the ultrasound image or may correspond the time with the number of frames, for example, assuming that the ultrasound image data has 1000 frames of ultrasound images in total, the frames of the 1000 frames of images are ordered by the generation time, the achilles tendon position corresponding to the 500 th ultrasound image is the middle of the achilles tendon, and the 333 rd ultrasound image corresponds to the 1/3 position of the achilles tendon. The number of frames of these 1000 frames of images is equally divided, that is, the achilles tendon is equally divided, so that the achilles tendon position corresponding to each ultrasound image can be obtained.
The processor 20 matches the ultrasound image of the same location in the third ultrasound image data with the ultrasound image of the same location in the fourth ultrasound image data to obtain an ultrasound image set. For example, the processor 20 sequentially samples the third ultrasound image data by a preset sampling manner (such as equally sampling) to obtain a plurality of ultrasound images, and sequentially samples the fourth ultrasound image data by a preset sampling manner to obtain a plurality of ultrasound images; and matching the plurality of ultrasonic images obtained by sequentially sampling the third ultrasonic image data with the plurality of ultrasonic images obtained by sequentially sampling the fourth ultrasonic image data one by one to obtain ultrasonic image groups at a plurality of positions.
The second adaptation method requires the aid of other means, for example, a sensor for detecting the height of the probe, such as a laser distance measuring sensor, etc., being provided on the probe 10. The third ultrasonic image data are obtained by scanning the achilles tendon of the affected leg of the horse under the triggering of a plurality of preset probe heights by the probe 10 respectively; the fourth ultrasound image data is obtained by scanning the achilles tendon of the patient while the patient is healthy by the probe 10 under the triggering of a plurality of preset probe heights respectively. In other words, the scan of step 6 may be triggered by a sensor, which detects the probe height while the veterinary hand-held probe is moved along one end of the achilles tendon to the other, and automatically activates the probe when it is at a preset probe height, and then automatically stores the image to obtain an ultrasound image of the position of the achilles tendon corresponding to the probe height. Therefore, the veterinarian only needs to move the probe from one end of the achilles tendon to the other end, the operation is very simple, the automation degree is high, and the efficiency is improved. Of course, the sensor may also only prompt the veterinarian after the preset probe height, with the veterinarian manually operating to activate the probe, deposit the map, etc.
The scanning of the achilles tendon is performed by scanning the cross section of the achilles tendon to obtain an ultrasonic image. Since the ultrasound images are acquired with a known probe height trigger, the height of the cross section to which each ultrasound image belongs in the ultrasound image data is known. Further, the processor 20 matches the ultrasound images of the same height cross section in the third ultrasound image data with the ultrasound images of the same height in the fourth ultrasound image data to obtain an ultrasound image group.
The third adaptation method likewise requires the use of other means, for example, sensors for detecting the height of the probe, such as laser distance measuring sensors, etc., on the probe 10. The matching method comprises the following steps:
the processor 20 acquires first height data detected by a sensor on the probe 10 in the process of scanning the achilles tendon of the affected leg to obtain third ultrasonic image data; taking the height acquired by the sensor at the same moment as the height of the cross section of the ultrasonic image acquired by the probe at the moment; in other words, the processor 20 generates an ultrasonic image according to the ultrasonic echo data, and correlates the height detected by the sensor at the same time to the ultrasonic image, where the height correlated to the ultrasonic image is the height where the probe scans to obtain the ultrasonic image, that is, the height of the achilles tendon cross section to which the ultrasonic image belongs. The processor 20 acquires second height data detected by the sensor on the probe in the process of scanning the achilles tendon of the patient when the patient is healthy and obtaining fourth ultrasonic image data; and taking the height acquired by the sensor at the same moment as the height of the cross section of the ultrasonic image acquired by the probe at the moment.
The processor 20 matches the third ultrasound image data with ultrasound images of the same height of the cross section in the fourth ultrasound image data to obtain an ultrasound image set. This approach is more data-handling than the second approach. The height sensor is used for determining the position (height) of the achilles tendon corresponding to the ultrasonic image, so that the accuracy is higher.
Similarly, the step is the same as the step 2 in the above embodiment, and only the first ultrasound image data is required to be replaced with the third ultrasound image data, and the second ultrasound image data is required to be replaced with the fourth ultrasound image data, which is not described herein.
Likewise, after step 7, the processing manner of the ultrasonic image group may be "automatic" (see fig. 7) and "manual" (see fig. 8). In the "automatic" mode, step 7 is followed by the following steps:
step 8, the processor 20 acquires the achilles tendon region in the two ultrasonic images of the ultrasonic image group at the same position.
The processor 20 may automatically identify the achilles tendon region in the two ultrasound images of the co-located ultrasound image set. For example, the processor 20 inputs two ultrasound images of the co-located ultrasound image set into a pre-trained deep learning model or machine learning model, respectively, to obtain achilles tendon regions in the two ultrasound images of the ultrasound image set, although image recognition techniques may be used to determine the achilles tendon regions in some embodiments.
The processor 20 may also display the co-located ultrasound image set via a display, with the achilles tendon region marked on the ultrasound images of the ultrasound image set by the veterinarian. The processor 20 receives, via the input device, the marked achilles tendon region in one of the ultrasound images of the set of ultrasound images of the user at the same location, and determines it as the achilles tendon region of the ultrasound image; likewise, the achilles tendon region marked by the user in another ultrasound image is received through the input device and determined as the achilles tendon region of the ultrasound image.
Whether the achilles tendon area is automatically identified by the processor 20 or manually marked by the user, it can be further processed to facilitate the calculation of subsequent amounts of discrepancy. For example, as shown in fig. 6, the processor 20 takes one of the longest line segments at any two points on the boundary of the achilles tendon region (indicated by a broken line in the figure) as a major axis a, takes a line segment connecting the two points on the boundary of the achilles tendon region and overlapping with a perpendicular to the major axis as a minor axis b, and takes an ellipse (indicated by a solid line in the figure) defined by the major axis a and the minor axis b as a final achilles tendon region.
In some embodiments, the user may also adjust whether the achilles tendon region is automatically identified, manually marked by the user, or further processed into an elliptical achilles tendon region (the final achilles tendon region described above). That is, the processor marks the boundaries of the achilles tendon region in the set of ultrasound images displayed by the display so that the user can adjust the boundaries. The processor 20 receives an operation of adjusting the boundary of the achilles tendon region by the user through the input device, adjusts the boundary of the achilles tendon region according to the operation, updates the display, and performs calculation with the latest achilles tendon region in the subsequent step.
Similarly, this step is identical to the above step 3, and differs only in that: in displaying two ultrasound images of an ultrasound image set, the processor 20 marks the attribute of the health of the ultrasound image (i.e., marks whether the ultrasound image is currently acquired or acquired while healthy), and therefore will not be described in detail herein.
Step 9, the processor 20 obtains and outputs a difference quantity for representing the size difference of the two achilles tendon regions according to the achilles tendon regions of the two ultrasonic images in the ultrasonic image group at the same position.
The difference amount may include at least one of a difference in the areas of the two achilles tendon regions, a normalized difference in the areas of the two achilles tendon regions, a difference in the circumferences of the two achilles tendon regions, and a normalized difference in the circumferences of the two achilles tendon regions. If the latest achilles tendon region is the above-described elliptical achilles tendon region, the processor 20 calculates the achilles tendon region area, the achilles tendon region perimeter, and the like from the long and short axes of the ellipse, and further calculates the above-described difference. If the most recent achilles area is not a standard ellipse, the processor 20 may count the total number of pixels in the achilles area, multiply the actual area represented by each pixel to obtain the achilles area, count the total number of pixels at the boundary of the achilles area, multiply the length or width of the corresponding pixel to obtain the perimeter of the achilles area, and calculate the difference. Of course, it is also possible to first superimpose the two achilles tendon regions to obtain a difference region, and to obtain an area difference and/or a perimeter difference according to the difference region. The normalized difference of the areas of the two achilles tendon regions can be obtained by the existing method, for example, the normalized difference is: the absolute value of the difference in the areas of the two achilles tendon regions divided by the area of the large achilles tendon region, i.e., the normalized difference in the areas of the two achilles tendon regions is the stenosis ratio of the areas of the two achilles tendon regions. Similarly, the normalized difference of the circumferences of the two achilles tendon regions can be obtained by the existing method, for example, the normalized difference is: the absolute value of the difference in the circumferences of the two achilles tendon regions divided by the circumference of the large achilles tendon region.
The processor 20 outputs the difference amount, for example, by a display. When the difference is displayed, the corresponding achilles tendon position can be displayed, and the steps are matched with the ultrasonic image groups, so that the corresponding achilles tendon positions and the difference are displayed for veterinary reference. For example, a schematic diagram of the horse leg is displayed on a display interface of the display, and the achilles tendon position and the corresponding difference amount thereof are marked on the schematic diagram. Different achilles tendon positions and their difference amounts may be displayed simultaneously or separately.
Processor 20 also stores the plurality of achilles tendon positions and their discrepancies in memory 80, providing a corresponding display interface for subsequent review by a veterinarian. For example, a veterinarian operates an input device to issue instructions for viewing the amount of historical discrepancy. Processor 20, in response to instructions for viewing the historical variance, obtains the variance for different times of the same achilles tendon position of the current horse; and drawing a differential volume curve according to differential volumes obtained at different periods of the same achilles tendon position, outputting the differential volume curve, and likewise, outputting the differential volume curve to a display to display the differential volume curve. The doctor can evaluate the recovery condition of the achilles tendon comprehensively.
The step is the same as the step 4, and will not be described here.
In the "manual" mode, step 7 is followed by the following steps:
step 8', processor 20 outputs the co-located ultrasound image set. For example, the processor 20 outputs the co-located ultrasound image set to the display for display, and may also mark the detection period of the ultrasound image (i.e., mark whether the ultrasound image is detected while healthy or unhealthy) when both ultrasound images of the ultrasound image set are displayed. After the veterinarian sees the ultrasonic image of the health state and the ultrasonic image of the injured state of the same achilles tendon position, the achilles tendon difference of the achilles tendon position can be measured, compared and calculated by himself, and therefore the achilles tendon condition of the injured leg is judged. Of course, the achilles tendon region may also be automatically identified and displayed by the ultrasonic imaging apparatus, see step 3 of the embodiment of fig. 2, which is not described herein. It can be seen that this step is the same as the above step 3', and will not be described here again.
As shown in fig. 11, in the embodiment shown in fig. 11, the method for inspecting achilles tendon of the target object by using the ultrasonic imaging apparatus specifically includes the following steps:
in step A1, the processor 20 acquires ultrasound image data of the achilles tendon of the affected leg of the target subject during at least two different detection periods. The ultrasound image data includes ultrasound images of cross-sections at multiple locations of the achilles tendon. Likewise, the ultrasound image data may be obtained from other devices, or may be obtained by the present ultrasound imaging device scanning the achilles tendon of the target object, the latter being illustrated as an example in this embodiment. Taking horse racing as an example, the horse racing needs to periodically perform physical examination including ultrasonic examination, and further needs to perform ultrasonic examination for a period of time after the achilles tendon is injured, so that the recovery condition of the horse racing achilles tendon can be conveniently known. Therefore, the ultrasonic image data of the achilles tendon of the affected leg in at least two different detection periods, namely the ultrasonic image data obtained by detecting the achilles tendon of the affected leg in at least two different time periods, or the ultrasonic image data obtained by at least two ultrasonic inspection. The ultrasonic image data of at least two different detection periods can be obtained by scanning corresponding achilles tendons (achilles tendons of affected legs) by the probe according to a preset scanning method. The ultrasonic image data of the same achilles tendon obtained by detection in different detection periods can well ensure the accuracy of the subsequent matching of the ultrasonic images of the same position by the same scanning method. The details of the sweeping technique are described in the foregoing embodiments, and are not described herein.
For example, the input device of the ultrasonic imaging apparatus is provided with a smart achilles key, which may be a physical key or a virtual key on the display interface. The user activates the intelligent achilles key and then issues an instruction to initiate an achilles examination. The processor 20 receives an instruction for starting an achilles tendon examination through the input device, and in response to the instruction, enters an achilles tendon examination mode. And the user presses the intelligent achilles tendon key again, and then the achilles tendon inspection mode is exited.
After entering the achilles tendon examination mode, the achilles tendon can be scanned. The processor 20 thaws the image, the user operates the probe to scan the image according to a preset scanning method, and the processor 20 scans the achilles tendon of the target object correspondingly through the probe, namely, transmits ultrasonic waves, receives ultrasonic echo signals and processes the ultrasonic echo signals, obtains ultrasonic image data (such as one or more frames of ultrasonic images are cached) and freezes the ultrasonic image data. The user operates the input device to issue a map storing instruction, and the processor 20 stores the scanned ultrasonic image data of the achilles tendon at the current period after receiving the map storing instruction through the input device. After at least two different periods of achilles tendon examination, at least two different detection periods of ultrasound image data are stored in memory 80 so that subsequent operations can be performed.
Step A2, the processor 20 matches the ultrasonic image data of the achilles tendon of the affected leg in at least two different detection periods to obtain ultrasonic image sets of multiple positions. Taking a target object as an example of a horse, if the affected achilles tendon is the anterior achilles tendon, 7 matched ultrasonic image groups can be provided; if the achilles tendon of the affected leg is the achilles tendon of the trailing leg, 9 groups of matched ultrasonic image groups can be provided. The ultrasound image set at any one location includes: ultrasound images of the cross section at the location at the at least two different detection times. That is, the processor 20 can determine, by matching, the ultrasound images at the same achilles tendon position in the ultrasound image data at each detection period, and generalize the ultrasound images at the same achilles tendon position into the ultrasound image group at the same achilles tendon position for convenience of description. The specific matching method is the same as the above embodiment.
For example, a first matching method is adopted, and the matching method has relevance with the scanning method of one step, namely, the preset scanning method is required to be: the probe 10 is moved at a constant speed along one end of the achilles tendon to the other end for continuous scanning. Processor 20 determines the locations of the achilles tendons corresponding to the plurality of ultrasound images in the ultrasound image data based on the temporal order of the plurality of ultrasound images. The processor 20 then matches the ultrasound images of the same achilles tendon position in the ultrasound image data for each of the different detection periods to obtain an ultrasound image set. By adopting the matching method and matching with the scanning method of the user, the ultrasonic images of the same achilles tendon position in different detection periods can be conveniently and rapidly matched.
The second adaptation method requires the aid of other means, for example, a sensor for detecting the height of the probe, such as a laser distance measuring sensor, etc., being provided on the probe 10. The probe 10 and the transducer are operated synchronously, so that the height of the cross section to which each ultrasound image belongs in the ultrasound image data is known (the height is detected by the transducer). Further, the processor 20 matches the ultrasound images of the same height cross section in the ultrasound image data of each different detection period to obtain an ultrasound image group.
The third adaptation method likewise requires the use of other means, for example, sensors for detecting the height of the probe, such as laser distance measuring sensors, etc., on the probe 10. The processor 20 acquires the height data detected by the sensor on the probe 10 in the process of scanning the achilles tendon to obtain ultrasonic image data; and taking the height acquired by the sensor at the same moment as the height of the cross section of the ultrasonic image acquired by the probe at the moment. Thus, the height of the cross section to which each ultrasound image belongs is also known, and the processor 20 matches the ultrasound images of the same height cross section in the ultrasound image data of each different detection period to obtain an ultrasound image group.
Step A3, the processor 20 compares the size difference of the achilles tendon regions between the ultrasonic images of the ultrasonic image group, obtains at least one difference amount and outputs the difference amount, wherein the difference amount is used for representing the difference of the sizes of the two achilles tendon regions. The processor 20 may output the difference amount by displaying the difference amount on a display of the human-machine interaction device. The difference reflects the difference of the sizes of the achilles tendon areas of the two ultrasonic images, so that the difference obtained by one ultrasonic image group is obtained by subtracting 1 from the number of ultrasonic images in the group, for example, one ultrasonic image group only comprises ultrasonic images of two detection periods, and only one difference is obtained; the ultrasound image including three detection periods has two differences. Specifically, the processor 20 acquires the achilles tendon region in each of the ultrasound images of the same ultrasound image group, and specifically may automatically identify the achilles tendon region, the achilles tendon region manually marked by the user, or further process the achilles tendon region to obtain an elliptical achilles tendon region, which is the same as the above embodiment. Further, the processor 20 obtains and outputs a corresponding difference amount according to the achilles tendon region of each ultrasonic image in the ultrasonic image group at the same position.
The amount of difference is a comparison of the achilles tendon regions of the ultrasound images and is therefore dependent on the ultrasound images within the ultrasound image set. The ultrasound image group includes an ultrasound image of the left achilles tendon and an ultrasound image of the right achilles tendon, and this embodiment is the same as the embodiment shown in fig. 2. The present embodiment is the same as the embodiment shown in fig. 7 in that the ultrasound image set contains both an ultrasound image of healthy achilles tendon and an ultrasound image of unhealthy (e.g., injured) achilles tendon. The ultrasonic image group includes a plurality of ultrasonic images (two or more) at detection times when the same achilles tendon is unhealthy, and the difference amount can reflect the recovery or deterioration of the achilles tendon.
In this embodiment, at least three different detection periods of ultrasound image data are adopted for at least two different detection periods of ultrasound image data, so that at least two different amounts can be obtained, and the recovery condition of the achilles tendon can be reflected. The processor 20 may output the difference amounts by displaying the numerical values of the respective difference amounts on a display, or may display the respective difference amounts in a curve, and the latter is described as an example in this embodiment. In step A2, the processor 20 specifically matches the ultrasonic image data of the achilles tendon of the affected leg in at least three different detection periods to obtain ultrasonic image sets of multiple positions; wherein the ultrasound image set for one location comprises: ultrasound images of the cross section at the location of the at least three different detection times. In step A3, the processor 20 compares the size differences of the achilles tendon regions between the ultrasound images of the ultrasound image set to obtain a plurality of difference amounts of the ultrasound image set, and draws a time-varying curve of the difference amounts of the ultrasound image set according to the obtained plurality of difference amounts of the ultrasound image set, and displays the time-varying curve of the difference amounts on a display interface of the display.
The difference amounts obtained by comparing the ultrasonic images at different detection times may be different in specific comparison modes, and three are exemplified below.
In a first comparison, the ultrasound image data acquired by the processor 20 for at least two different detection periods includes: ultrasound image data detected during a healthy period and ultrasound image data detected during a plurality of unhealthy periods. And comparing the ultrasonic images detected in the healthy period with the ultrasonic images detected in the unhealthy period to obtain difference values which can reflect the damage degree of the achilles tendon, and then making each difference value into a curve according to the time sequence to reflect the recovery condition of the achilles tendon. Specifically, the processor 20 compares the sizes of the achilles tendon regions with those of the non-healthy time ultrasonic images in the ultrasonic image group respectively, so as to obtain the difference between the non-healthy time ultrasonic images and the healthy time ultrasonic images; and drawing a curve of the difference quantity changing along with time according to the obtained difference quantity and outputting the curve. The time variation here is the order of the various unhealthy periods. For example, the group includes three ultrasound images B1, B2, and B3 of non-healthy periods, and the ultrasound images B0, B0 of healthy periods are detected earlier than B1, B1 is detected earlier than B2, and B2 is detected earlier than B3. The sizes of the achilles tendon regions B0, B1, B2, B3 are B0, B1, B2, B3, respectively. The difference of the ultrasonic image group is arranged into three according to the sequence of the detection periods: i b1-b 0I, I b2-b 0I, I b3-b 0I, where 'I' is the absolute sign, and the three differences are sequentially arranged in the same time coordinate system to obtain a curve of the difference changing with time, where the difference value is calculated in various ways, and the difference value is merely used as an example. The processor 20 displays a time-varying profile of the differential, with the absolute value of the differential seen by the veterinarian to decrease over time, indicating that the achilles tendon area size is approaching the size of the healthy period and that the achilles tendon is gradually recovering.
In a second comparison, the processor 20 acquires ultrasound image data for at least two different detection periods, and has at least three different detection periods. The detection periods can be compared with the ultrasonic images of the previous detection period respectively to obtain a series of difference amounts, and the absolute value of the difference amounts of the unhealthy periods can reflect the recovery degree of the achilles tendon, so that the generated difference amount curves can also reflect the recovery condition of the achilles tendon. Specifically, the processor 20 compares the size of the achilles tendon region with the ultrasonic image of one detection period and the ultrasonic image of the previous detection period in the ultrasonic image group respectively, so as to obtain the difference between the ultrasonic images of adjacent detection periods; and drawing a curve of the difference quantity changing along with time according to the obtained difference quantity and outputting the curve. Taking B0, B1, B2 and B3 as examples, the difference amounts of the ultrasonic image groups are arranged in sequence of the detection periods as follows: and (3) sequentially arranging the three difference amounts in the same time coordinate system to obtain a time-varying curve of the difference amounts, wherein the time variation is the sequence of each detection period. The processor 20 outputs a curve, which may be a curve showing the variation of the difference amount with time through a display, and marks the difference amount related to the health period in the curve, for example, data points of the difference amount related to the health period are shown in the curve in a differential mode, so that the doctor can know the injury degree of the achilles tendon by seeing the difference amount, and can know the recovery degree of the achilles tendon by seeing the difference amount.
In a third comparison, the ultrasound image data acquired by the processor 20 for at least two different detection periods includes: ultrasound image data for a current detection period and ultrasound image data for a plurality of detection periods preceding the current detection period. For example, after performing an ultrasonic examination on the current achilles tendon of the patient to obtain ultrasonic image data of the current detection period, the detection process shown in fig. 11 may be performed, and the obtained difference amounts may be compared with the previously detected ultrasonic images based on the ultrasonic image of the current detection period in the group, so as to reflect the injury degree of the achilles tendon, and then the difference amounts may be made into curves according to time sequence, so as to reflect the recovery condition of the achilles tendon. Specifically, the processor 20 compares the size of the achilles tendon region with the ultrasonic image of the current detection period and the ultrasonic image of each detection period before the current detection period in the ultrasonic image group, respectively, so as to obtain the difference between the ultrasonic image of the current detection period and the ultrasonic image of each detection period before the current detection period; and drawing a time-varying curve of the difference according to the obtained difference and outputting the curve. The time change here is the sequence of the respective detection periods. Taking b0, b1, b2 and b3 as examples, the difference amounts of the ultrasonic image groups are arranged in sequence of detection periods as follows: and (3) sequentially arranging the three difference amounts in the same time coordinate system to obtain a curve of the difference amount changing along with time. The processor 20 output curve may be a curve showing the amount of difference over time via a display, and the processor 20 may also mark the amount of difference (Ib 3-b 0I) related to the health period in the curve to show the distinction.
The second and third comparison methods do not rely on ultrasound images detected while healthy, so in some embodiments, the ultrasound image data for the at least three different detection periods may include: at least three non-healthy periods, so that the recovery condition of the corresponding achilles tendon position can be known through the difference curve.
Because there are a plurality of ultrasound image sets matched by the processor 20 in step A2, the display interface may display a time-varying curve of the difference amounts of all the ultrasound image sets, and may display only a time-varying curve of the difference amounts of a part of the ultrasound image sets. For example, processor 20 displays a time-varying profile of the amount of difference for each ultrasound image set on the display interface of the human-machine interaction device so that the veterinarian can see how the injured achilles tendon is recovered from the different locations. For another example, the processor 20 displays a time-varying curve of the difference between the ultrasonic image sets selected by the user on the display interface of the man-machine interaction device, that is, the veterinarian can select the achilles tendon position to be viewed, and then the above steps are performed, and the display interface can display a time-varying curve of the difference between the achilles tendon positions selected by the veterinarian. For example, since the degree of injury is different at different positions of the same achilles tendon, and the difference curve of the position where injury is the heaviest can be displayed, the processor 20 may display the curve of the difference of the ultrasound image group where the maximum difference is located with time on the display interface of the man-machine interaction device.
In this embodiment, the curves of the difference amounts displayed on the display interface of the man-machine interaction device, which change with time, are multiple, and the curves of the difference amounts, which change with time, are simultaneously displayed on the same screen, so that the veterinarian can comprehensively evaluate the recovery condition of the whole achilles tendon.
In summary, the present invention can reflect the extent of achilles injury by comparing the sizes of achilles tendon regions at different times at the same achilles tendon position to obtain the difference, and can reflect the recovery of achilles tendon by drawing the difference at different times into a curve, thereby improving the efficiency of achilles tendon examination.
