Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computer application, in particular to an ultrasonic movie playing control method and device, equipment and storage medium. BACKGROUND

[0002] With the rapid development of ultrasonic medicine, the application of ultrasonic is more and more widely. Ultrasonic has good resolution ability to human soft tissue, and can obtain useful signals with high dynamic range, which is beneficial to identify the micro lesions of biological tissue. Ultrasonic movie can be obtained through ultrasonic scanning. The ultrasonic movie has a large number of frames, and the user can control the playing of the ultrasonic movie by rotating the trackball until the target frame is found.

[0003] The control of the playing of the ultrasonic movie mainly reflects the adjustment of the frame number of the ultrasonic movie. Different rotating speeds of the trackball correspond to different rotating frame numbers. The corresponding relationship set by different trackballs is different. The effect of the medium speed adjustment of some trackballs is close to the fast adjustment. If the user wants to quickly adjust from the 10th frame of the ultrasonic movie to the 35th frame, the medium speed rotating of the trackball will cause the frame number of the ultrasonic movie to be adjusted too fast, and the 80th frame may be directly reached, and it needs to be adjusted back again. The effect of the fast adjustment of some trackballs is close to the medium speed adjustment, which will cause the frame number of the ultrasonic movie to be adjusted too slowly. If the user wants to adjust from the 10th frame of the ultrasonic movie to the 500th frame, the trackball needs to be rotated multiple times to achieve the adjustment. Therefore, the playing of the ultrasonic movie cannot be effectively controlled. SUMMARY

[0004] The purpose of the present application is to provide an ultrasonic movie playing control method, device, equipment and storage medium to effectively control the playing of the ultrasonic movie.

[0042] In order to make the person skilled in the art better understand the present application, the present application is further described in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0043] Referring to Figure 1 As shown in the figure, an implementation flowchart of an ultrasonic movie playing control method provided by an embodiment of the present application is taken as an example, and the method is applied to an ultrasonic device. The method can include the following steps:

[0044] S110: Obtain the adjustment data of the user on the trackball of the ultrasonic movie under different dialing levels.

[0045] In actual application, an ultrasonic movie playing scene is as follows: when the total frame number of the ultrasonic movie is large, the user quickly dials the trackball, adjusts the frame number of the ultrasonic movie by tens of frames or hundreds of frames, first locates the approximate range of the target frame, then dials the trackball at medium speed, plays the ultrasonic movie under the premise of ensuring that no picture information is missed, when approaching the target frame, the user dials the trackball at slow speed, adjusts the frame number of the ultrasonic movie frame by frame, and finally accurately locates the target frame.

[0046] The slow, medium and fast mentioned above are examples. In the embodiment of the present application, the speed is represented by dialing levels. Each dialing level can correspond to a dialing speed range. The higher the dialing level, the larger the dialing speed range included in the corresponding dialing speed range, that is, the faster the dialing speed.

[0047] Through data acquisition and other methods, the adjustment data of the user on the trackball of the ultrasonic movie under different dialing levels can be obtained. Specifically, the adjustment data of multiple users on the trackball of the ultrasonic movie under different dialing levels can be obtained, and the adjustment data of the same user on different trackballs of the ultrasonic movie under different dialing levels can also be obtained. The ultrasonic movie can be any ultrasonic movie.

[0048] For each dialing level, the adjustment data under the current dialing level can include: the duration of each dialing of the trackball under the current dialing level, the offset range in unit time of each dialing of the trackball, and the expected value of the dialing frame number of each dialing of the trackball. The current dialing level refers to the dialing level currently targeted.

[0049] The duration of each dialing of the trackball under the current dialing level refers to the duration of dialing the trackball once using the dialing speed under the current dialing level, for example, the duration is 0.4 seconds.

[0050] The range of the offset of the trackball per unit time in each dialing level is the range of the offset of the trackball per unit time in the current dialing level using the dialing speed in the current dialing level, for example, the unit time can be 100 milliseconds;

[0051] The expected value of the dialing frame number of the trackball per dialing in the current dialing level can be obtained through the interaction with the user. For example, if the dialing frame number does not meet the user's expectation when the user dials the trackball once using the dialing speed in the current dialing level, the user can feed back the adjustment information to adjust the dialing frame number to meet his own expectation. After adjusting the dialing frame number, the user can continue to dial the trackball once using the dialing speed, and if the adjusted dialing frame number meets the user's expectation, the user can feed back the confirmation information to determine the adjusted dialing frame number as the expected value of the dialing frame number of the trackball per dialing in the current dialing level. It can be seen that in any dialing level, the dialing frame number generated by dialing the trackball once can be adjusted based on the feedback of the user until the corresponding dialing frame number can meet the user's expectation. Therefore, for different users, the dialing frame number generated by dialing the trackball once in the same dialing level can be different or the same, so that the dialing effect can be customized according to the use habits of different users.

[0052] It should be noted that the offset is a physical quantity used to describe the moving direction and distance of the trackball. One offset can correspond to the size of one pixel, and in the process of adjusting the cine loop frame number, the cine loop frame number to be adjusted is mainly calculated according to the offset of the trackball.

[0053] S120: Determine the change interval of the trackball offset and the dialing frame number corresponding to each dialing level according to the debugging data.

[0054] After obtaining the debugging data of the user dialing the trackball of the cine loop in different dialing levels, the debugging data can be counted to obtain the change interval of the trackball offset and the dialing frame number corresponding to each dialing level.

[0055] Specifically, for each dialing level, the change interval of the trackball offset and the dialing frame number corresponding to the current dialing level can be determined according to the debugging data obtained in the current dialing level. That is, for each dialing level, the corresponding change interval is determined based on the debugging data obtained in each dialing level. The current dialing level is the dialing level currently targeted.

[0056] The change interval corresponding to the current dialing level can include at least one of the following: the absolute value range of the maximum offset in the current dialing level, the duration range of dialing the trackball once, the expected value range of the dialing frame number of the trackball per dialing, and the number range of the offset absolute value of the trackball per dialing in the absolute value range.

[0057] For example, the dialing levels include a first level, a second level and a third level, wherein the first level corresponds to a slow dialing speed, the second level corresponds to a medium dialing speed, and the third level corresponds to a fast dialing speed.

[0058] Through analysis of the debugging data corresponding to the second dialing level, it can be obtained that, under the second dialing level, the absolute value range of the maximum offset is 7-20, the duration range of dialing the trackball once is 0.4-0.5 seconds, the expected value range of the dialing frame number of dialing the trackball once is 30-60 frames, and the range of the number of times that the absolute value of the offset of dialing the trackball once is within the absolute value range of the maximum offset is 5-6 times.

[0059] Through analysis of the debugging data corresponding to the third dialing level, it can be obtained that, under the third dialing level, the absolute value range of the maximum offset is greater than 40, the duration range of dialing the trackball once is 0.6-0.7 seconds, the expected value range of the dialing frame number of dialing the trackball once is 100-300 frames, and the range of the number of times that the absolute value of the offset of dialing the trackball once is within the absolute value range of the maximum offset is 10-12 times.

[0060] Through the change intervals of the trackball offset and the dialing frame number corresponding to the second dialing level and the third dialing level, it can be preliminarily obtained that, if the absolute value of the maximum offset is less than 7 when dialing the trackball once, it can be considered that the dialing speed of this time is in the first dialing level, which belongs to slow speed; if the absolute value of the maximum offset is greater than 7 and less than 20, it can be considered that the dialing speed of this time is in the second dialing level; and if the absolute value of the maximum offset is greater than 40, it can be considered that the dialing speed of this time is in the third dialing level.

[0061] S130: determining the offset critical point of each dialing level and the dialing frame number corresponding to the offset critical point based on the change intervals corresponding to each dialing level.

[0062] After determining the change intervals of the trackball offset and the dialing frame number corresponding to each dialing level according to the debugging data of the user dialing the trackball of the ultrasonic movie under each dialing level, the offset critical point of each dialing level and the corresponding dialing frame number can be determined based on the change intervals corresponding to each dialing level.

[0063] Each dialing level corresponds to a respective offset critical point. For any dialing level, the offset critical point corresponding to the dialing level can be the starting point of the dialing level, or can be the adjacent point of the dialing level and the adjacent dialing level.

[0064] Specifically, for each dialing level, the offset critical point of the current dialing level can be determined according to the absolute value range of the maximum offset under the current dialing level. For example, if the absolute value range of the maximum offset under the current dialing level is 7-20, the offset critical point of the current dialing level can be determined as 7, or a smaller value in the range of 7-20, such as 10.

[0065] After the offset critical point of the current dialing level is determined, the dialing frame number corresponding to the offset critical point of the current dialing level can be further determined according to the duration range of the trajectory ball dialing once under the current dialing level, the expected value range of the dialing frame number of the trajectory ball dialing once, and the range of the number of times that the absolute value of the offset of the trajectory ball dialing once is within the absolute value range of the maximum offset.

[0066] In an embodiment of the present application, the offset critical point of the current dialing level can be the starting point of the current dialing level. The number of units of time contained in the minimum value in the duration range of the trajectory ball dialing once under the current dialing level can be determined first. The minimum value of the expected value range of the dialing frame number of the trajectory ball dialing once is divided by the number of units of time, and then divided by the minimum value of the range of the number of times that the absolute value of the offset of the trajectory ball dialing once is within the absolute value range of the maximum offset. The result obtained is rounded up, and the dialing frame number corresponding to the offset critical point of the current dialing level can be obtained.

[0067] Of course, if the offset critical point of the current dialing level is the adjacent point of the current dialing level and the next higher dialing level, the minimum values in the above example can be replaced by maximum values to obtain the dialing frame number corresponding to the offset critical point of the current dialing level.

[0068] For example, the determined offset critical points of each dialing level and the corresponding dialing frame numbers can be (7, 1), (10, 2), (20, 4), (40, 20), etc. The former number represents the offset critical point, and the latter number represents the corresponding dialing frame number.

[0069] S140: The offset critical points of each dialing level and the dialing frame numbers corresponding to the offset critical points are fitted to obtain a data trend curve.

[0070] S150: When playing the ultrasound movie, the dialing frame number corresponding to the corresponding dialing operation is determined based on the data trend curve and the trajectory ball offset generated by the dialing operation of the trajectory ball.

[0071] The horizontal axis of the data trend curve is the trajectory ball offset, and the vertical axis is the dialing frame number.

[0072] In the embodiments of the present application, after the offset critical point of each dialing level and the corresponding dialing frame number are determined, the offset critical point of each dialing level and the dialing frame number corresponding to the offset critical point can be further fitted to obtain a data trend curve.

[0073] Specifically, the offset critical point of each dialing level and the dialing frame number corresponding to the offset critical point can be fitted by a function to obtain a data trend curve. The horizontal axis of the data trend curve is the trackball offset, and the vertical axis is the dialing frame number.

[0074] The function fitting can be a cubic function fitting. The cubic function can be specifically:

[0075] y=p1*x 3 +p2*x 2 +p3*x+p4

[0076] Wherein, x represents the trackball offset, y represents the dialing frame number, and p1, p2, p3, and p4 are variable coefficients.

[0077] The finally obtained data trend curve can be as shown in Figure 2 The corresponding cubic function is:

[0078] y=0.002*x 3 -0.077*x 2 +1.065*x-2.173.

[0079] After obtaining the data trend curve, when playing the cine loop, the trackball offset generated by each dialing operation of the trackball can be determined based on the data trend curve and the trackball offset generated by each dialing operation of the trackball, and the dialing frame number corresponding to each dialing operation of the trackball can be determined. The cine loop frame is adjusted based on the dialing frame number to control the playing of the cine loop.

[0080] Of course, if other functions can achieve the same or better fitting effect as the cubic function, other functions can also be used to fit the offset critical point of each dialing level and the corresponding dialing frame number.

[0081] After the method provided in the embodiments of the present application is applied, the adjustment data of the ultrasonic movie under different dialing levels is obtained by the user dialing the trackball, and according to the adjustment data, the change interval of the trackball offset and the dialing frame number corresponding to each dialing level is determined, and then the offset critical point of each dialing level and the corresponding dialing frame number are determined. The offset critical point of each dialing level and the corresponding dialing frame number are fitted to obtain a data trend curve. In this way, when the ultrasonic movie is played and controlled, based on the data trend curve and the trackball offset generated by the dialing operation of the trackball, the dialing frame number corresponding to the dialing operation of the trackball can be determined, so that the dialing operation of the trackball by the user can obtain appropriate dialing frame number changes that meet the user's expectations, and the situation that the frame number changes too fast or too slow can be avoided. At the same time, the data trend curve obtained by fitting has good universality and generality, and can be applied to the ultrasonic movie adjustment under various trackballs and frame numbers, so that the speed of the trackball for adjusting different ultrasonic movie frame numbers can be effectively unified, and the ultrasonic movie can be effectively controlled.

[0082] In an embodiment of the present application, after the data trend curve is obtained, the method can further include the following steps:

[0083] Step one: obtaining adjustment information according to the adjustment operation of the user on the trackball offset and the corresponding dialing frame number of each dialing level, the adjustment information including the trackball offset and the corresponding dialing frame number of each dialing level;

[0084] Step two: based on the adjustment information, adjusting the data trend curve, so that when the ultrasonic movie is played and controlled, based on the adjusted data trend curve and the trackball offset generated by the dialing operation of the trackball, the dialing frame number corresponding to the dialing operation of the trackball is determined.

[0085] For the convenience of description, the above two steps are combined for description.

[0086] In the embodiments of the present application, after the offset critical point of each dialing level and the corresponding dialing frame number are fitted to obtain the data trend curve, the data trend curve can be fed back to the user. The user can adjust the trackball offset and the corresponding dialing frame number of each dialing level according to his own habits, and return the adjustment information, which includes the trackball offset and the corresponding dialing frame number of each dialing level.

[0087] After obtaining the adjustment information, the data trend curve can be adjusted based on the adjustment information, so that the adjusted data trend curve is more in line with the user's feeling. After adjusting the data trend curve, when performing the control of the ultrasound movie playback, the number of frames corresponding to the dialing operation of the trackball can be determined based on the adjusted data trend curve and the trackball offset generated by the dialing operation of the trackball. In this way, the playback of the ultrasound movie can be more effective and more in line with the user's needs.

[0088] In an embodiment of the present application, the method can further include the following steps:

[0089] When performing the control of the ultrasound movie playback, for the dialing operation of the trackball, if it is detected that the absolute value of the maximum trackball offset generated by the current dialing operation is greater than a set threshold, the number of frames corresponding to the current dialing operation can be determined as a preset upper limit value. The set threshold and the preset upper limit value can be set based on the data input by the user through the input device.

[0090] In the embodiment of the present application, the upper limit value of the number of frames can be set, and when performing the control of the ultrasound movie playback, for the dialing operation of the trackball, the absolute value of the maximum trackball offset generated by the current dialing operation can be detected, and if it is detected that the value is greater than a set threshold, the number of frames corresponding to the current dialing operation can be determined as a preset upper limit value. In this way, the phenomenon that the number of frames changes too fast and is uncontrollable when the number of frames of the ultrasound movie is quickly adjusted can be effectively prevented.

[0091] In the embodiment of the present application, the offset critical point of each dialing level and the corresponding change frame of the ultrasound movie are fitted to obtain a data trend curve, and the control of the ultrasound movie playback is performed based on the data trend curve. When the trackball is dialled once in the medium-speed adjustment range, the number of frames changes relatively slowly, for example, is concentrated in tens of frames, ensuring the continuity of the picture in the adjustment process. In the fast adjustment range, the number of frames changes relatively steeply, for example, can reach hundreds of frames, achieving the fast adjustment of the number of frames of the ultrasound movie.

[0092] When the ultrasound equipment freezes or plays back the ultrasound movie, the doctor will adjust the current number of frames of the movie by dialing the trackball until reaching a certain frame that the doctor wants, and then freeze the ultrasound movie from the frame or start playing back the ultrasound movie from the frame. The main factor affecting the speed of adjusting the number of frames of the movie is the offset of the trackball in a unit of time. When the doctor manually dials the trackball, the number of frames adjusted by different trackball offsets is different.

[0093] In order to enable the doctor to quickly locate to the frame he wants, the embodiment carries out function fitting on the historical use data of the doctor dialing the trackball, and controls the dialing speed and the dialing frame number according to the fitting result, which not only conforms to the use habit of the doctor, but also can realize quick and accurate positioning. Specifically, the ultrasound equipment executes the following steps:

[0094] 1. Historical use data collection.

[0095] The ultrasound equipment is provided with different grades of dialing speed in advance, so that the use habit of the doctor is collected in grades. For example, the data of the doctor dialing the trackball quickly, the data of the doctor dialing the trackball at medium speed, and the data of the doctor dialing the trackball slowly are collected.

[0096] The collected data mainly includes: the duration of dialing the trackball once; the offset range in unit time of dialing the trackball once; the expected value of the movie frame number change (i.e. the dialing frame number) of dialing the trackball once, etc.

[0097] 2. Analysis and statistics of the collected data.

[0098] Through repeated analysis of the operation of the doctor dialing the trackball and the movie frame number change he hopes to achieve, the statistical value under any dialing grade can be obtained.

[0099] For example, under the medium-speed dialing grade, the doctor dials the trackball once, the duration is 0.4-0.5 seconds, the expected value of the movie frame number change is 30-60 frames, the absolute value of the maximum offset is concentrated in 7-20, and the number of times in the offset collected in this dialing of the trackball is about 5-6 times in the maximum offset range.

[0100] For another example, under the high-speed dialing grade, the doctor dials the trackball once, the duration is 0.6-0.7 seconds, the expected value of the movie frame number change is 100-300 frames, the absolute value of the maximum offset is above 40, and the number of times in the offset collected in this dialing of the trackball is about 10-12 times in the maximum offset range.

[0101] Accordingly, the analysis and statistics result can be obtained preliminarily: when the absolute value of the offset is less than 7, the dialing speed belongs to slow speed; when the absolute value of the offset is greater than 7 and less than 20, the dialing speed belongs to medium speed; and when the absolute value of the offset is greater than 40, the dialing speed belongs to fast speed. Among them, 7, 20 and 40 are the offset critical points, and the expected value of the movie frame number change corresponding to 7, 20 and 40 respectively is the corresponding dialing frame number.

[0102] 3. Fitting the above analysis and statistics result.

[0103] By collating and fitting the above analysis and statistical results, it is found that the characteristics of the cubic function are in line with the above data trends, so the cubic function is used to fit the above analysis and statistical results, and the fitting curve is obtained. The cubic function is y = p1*x 3 + p2*x 2 + p3*x + p4.

[0104] According to the characteristics of the cubic function, the parameters p1, p2, p3, and p4 are optimized to make the fitting effect more in line with the above analysis and statistical results.

[0105] The optimization process includes selecting the following four critical points to describe the trend characteristics of the curve:

[0106] The offset 7 is a slow critical point, corresponding to 1 frame of slow movement, denoted as (7, 1);

[0107] The offset 10 is a medium starting point, corresponding to 2 frames of movement, denoted as (10, 2);

[0108] The offset 20 is a fast starting point, corresponding to 4 frames of movement, denoted as (20, 4);

[0109] The offset 40 is a super-fast starting point, corresponding to 20 frames of movement, denoted as (40, 20); super-fast means that the user wants to adjust hundreds of frames at a time.

[0110] Based on the above four coordinates, the curve is fitted.

[0111] Then, according to the doctor's adjustment operation of the absolute value of the offset and the corresponding frame number, the critical points and the corresponding frame numbers are adjusted until the fitting curve meets the doctor's dialing habits. At this time, the Figure 2 curve and the corresponding function are obtained.

[0112] 4. Set the upper limit of frame number change.

[0113] Under normal circumstances, the faster the trackball is dialed, the larger the frame number adjustment. In order to prevent the frame number from changing too fast and being uncontrollable during fast adjustment, the upper limit of frame number change can be manually set. For example: detect the doctor's dialing trackball operation, if the frame number of this dialing is greater than the set threshold, then the dialing frame number corresponding to the current dialing operation is determined as the upper limit of frame number change, so as to avoid uncontrollable frame number change during adjustment.

[0114] 5. Ultrasound movie playback control.

[0115] In the scene of freezing or playing back the ultrasonic movie by the ultrasonic device, when receiving the doctor's dialing operation on the trackball, the dialing frame number corresponding to the current dialing operation is determined based on the fitting curve. It is determined whether the dialing frame number corresponding to the current dialing operation is greater than the set threshold. If it is greater than the set threshold, the pre-set upper limit of the frame number change is replaced by the dialing frame number corresponding to the current dialing operation. If it is less than the set threshold, no replacement of the dialing frame number is performed. The switching of the image frames of the ultrasonic movie is performed based on the dialing frame number corresponding to the current dialing operation, the play control is realized, and the freezing or playing back of the ultrasonic movie is realized from the target frame.
