It should be understood that although the terms first, second, etc. may be used to describe growth rates in embodiments of the present invention, these growth rates should not be limited to these terms. These terms are only used to distinguish growth rates from each other. For example, the first growth rate may also be referred to as the second growth rate, and similarly, the second growth rate may also be referred to as the first growth rate, without departing from the scope of embodiments of the present invention.

The embodiment of the invention provides a control method which is suitable for medical equipment. The medical device includes, but is not limited to, a CT (Computed Tomography) scanning device, an MR (magnetic resonance) scanning device, a PET (positron emission Tomography)/CT scanning device, and the like.
Please refer to fig. 1, which is a flowchart illustrating a method according to an embodiment of the present invention, the method including the following steps:
101. an initial seed point and a first growth algorithm are obtained.
Wherein the initial seed point is a pixel point in the image for tissue growth. The initial seed point is a reference point for tissue growth, and in the process of realizing tissue growth, a pixel point needs to be selected as a reference point for tissue growth first, and the pixel point is taken as a starting point for tissue growth.
102. And growing the initial seed points in a growth process according to the first growth algorithm to obtain a first growth result.
Tissue growth refers to the process of developing groups of pixels or regions into larger regions. The method comprises the steps of selecting an initial seed point as a reference point, then selecting adjacent pixel points similar to the gray level, texture color and other characteristics of the seed point from an image for growth through a first growth algorithm, and combining the pixel points into a region to realize tissue growth. And combining the pixel points to obtain a large area which is a first growth result.
103. And when the first growth result meets the preset condition, acquiring the specified operation.
Wherein the growth progress of the tissue growth is displayed by a progress bar. And the specified operation comprises the step of enabling the growth process to back to the specified state corresponding to the second growth result through the progress bar. The rollback to the designated state comprises locally rolling back to an intermediate state in the growth process, or completely rolling back to the initial state. The specifying operation specifically includes: dragging, clicking, or sliding the progress bar of the growth process causes the growth process to roll back to a specified state.
Specifically, when the progress bar for displaying the growth process starts to grow from the initial seed, the progress bar is displayed, and along with the growth, the execution subject correspondingly adjusts the position of the progress bar and the length of the progress bar, so that the position of the progress bar and the length of the progress bar are in a mapping relationship with the growth state; or, the progress bar for displaying the growth process may be displayed to the user after the first growth result is obtained, and the executing main body may further perform corresponding adjustment according to the growth result corresponding to the first growth algorithm, so that the position of the progress bar and a mapping relationship between the length of the progress bar and the growth state are obtained. Therefore, the execution main body can return the growth result of the tissue to a certain growth state according to the operation of the progress bar.
It should be noted that, before the execution main body obtains the specified operation, whether the execution main body is to obtain the specified operation may be triggered by determining whether the first growth result satisfies the first preset condition. Wherein the first preset condition is that the first growth result has a phenomenon of growth overflow. When the first growth result is judged to meet a first preset condition, namely the phenomenon of growth overflow occurs in the first growth result, triggering an execution main body to acquire a specified operation; and when the first growth result is judged not to meet the first preset condition, namely the phenomenon of growth overflow does not occur in the first growth result, the execution main body does not need to acquire the specified operation. Or, an instruction or action directly input to the execution subject by the user triggers the execution subject to acquire the specified operation.
104. And acquiring a second growth result from the first growth result according to the specified operation.
The designated operation and the growth state of the tissue have a corresponding relationship, and based on the corresponding relationship, the corresponding growth state can be determined by acquiring the input designated operation.
And the second growth result is a growth result corresponding to a certain growth state before the first growth result.
Specifically, after the first growth result is obtained, the terminal displays a progress bar of the growth process through the display interface, and the user drags, clicks or slides the progress bar to enable the current growth state to return to the corresponding previous state. For example, the user controls the state of the corresponding state by clicking the number of times the control clicks the progress bar. Step 103 and step 104 are realized in such a way that when the user clicks the growth control once, the tissue growth returns to the state A; when the user clicks the growth control twice, the tissue growth returns to the state B; when the user clicks the control for growth three times, the tissue growth reverts to the C state. The three states of the A state, the B state and the C state respectively correspond to a growth state, the A state is obtained by performing tissue growth on the basis of the B state, and the B state is obtained by performing tissue growth on the basis of the C state. For another example, the terminal displays a progress bar to the user, and the terminal may drag the progress bar. Step 103 and step 104 are specifically that the terminal obtains the operation of the user dragging the progress bar, then determines the position of the progress bar, and determines the growth state to which the first production result is returned according to the position of the dragging progress bar, so as to obtain a second growth result.
It should be noted that, the above-mentioned manners for implementing step 103 and step 104 are only two specific manners provided by the embodiments of the present invention, and are not to be taken as specific limitations of the present invention, and other manners for implementing step 103 and step 104 may also be available.
105. And calling a second growth algorithm, and growing the second growth result according to the second growth algorithm.
After step 104 is executed, it is desirable to obtain a more complete tissue, and the second growth result needs to be continued to grow, and in order to avoid the overflow of growth caused by continuing to use the first growth algorithm, the second growth algorithm is used in the present embodiment to continue to grow. Because the tissue growth is to select the adjacent pixel points with the similar characteristics of the gray scale, the texture color and the like of the seed points, the second growth algorithm is obtained by adjusting the gray scale threshold value in the first growth algorithm, the similarity of the texture color and the like of the seed pixel points, the overgrowth phenomenon caused by the regrowth is avoided, and the extracted tissue is accurate and complete.
According to the technical scheme provided by the embodiment of the invention, the designated operation input by the user has a corresponding relation with the growth state of the tissue, the user can retreat the tissue growth into any state by inputting the designated operation, the tissue structure in any state is extracted, and after the first growth result is retreated to the second growth result corresponding to the designated state before the growth overflow occurs, the second growth result obtained after the retreat is regrown by adopting the adjusted second growth algorithm through adjusting the growth algorithm, so that the problem of the growth overflow can be effectively avoided. Therefore, the method provided by the embodiment of the invention can remove other tissues generated by growth overflow in the tissue growth process, thereby effectively solving the problem of growth overflow in the tissue growth process and ensuring that the finally extracted tissues are more accurate.
Further, in order to ensure that the execution subject can implement accurate rollback when implementing rollback from one growth state to another growth state, an embodiment of the present invention provides another implementation manner, as shown in fig. 2, before obtaining the specified operation in step 103, the method further includes:
106. and acquiring the amplified display of the progress bar.
Specifically, the progress bar is subjected to amplification processing, so that the execution main body can acquire the progress bar after amplification display. The processing mode of performing amplification processing on the progress bar is the same as the mode of performing amplification processing on the terminal in the prior art, and the details of the present invention are not repeated herein.
According to the method provided by the embodiment, after the progress bar for displaying the growth process is amplified and displayed, the positions of the progress bar and the progress bar are amplified, and when a user operates the amplified and displayed progress bar through dragging or sliding, the progress bar can be accurately dragged to the specified position, so that the execution main body can accurately retreat the tissue from one growth state to another growth state.
Further, in the process of implementing step 102 to grow the initial seed points according to the first growth algorithm to obtain the first growth result, too fast tissue growth is effectively alleviated, and the occurrence of tissue growth overflow is reduced, which is provided by the embodiment of the present invention for step 102, and specifically includes:
1021. and calling a first growth algorithm according to a first preset iteration speed, and controlling the initial seed points to grow according to the first growth speed so as to obtain an initial growth result.
The tissue growth process is an iterative process, each pixel point can be iteratively grown, and the growth speed of the tissue growth is adjusted by changing the iterative speed. Because in the initial stage of tissue growth, the condition of growth overflow is not easy to occur, therefore, the first preset iteration speed of the growth algorithm can be called to be improved to a certain extent according to the requirement, thereby improving the growth speed of the initial stage of tissue growth and further shortening the time of tissue growth.
It should be noted that the setting of the first preset iteration speed may set different iteration speeds according to different tissues or organs, for example, the first preset iteration speed for blood vessel growth is 30 iterations per microsecond, the first preset iteration speed for lung trachea growth is 20 iterations per microsecond, and the like; alternatively, the first preset iteration speed of all organs or tissues may be set to the same speed, which is not specifically limited by the present invention.
1022. And judging whether the initial growth result meets a second preset condition.
Determining the tissue growth degree by judging whether the initial growth result meets a second preset condition, and when the initial growth result meets the second preset condition, determining that the growth process according to the first growth speed is finished, and entering a stage of growth according to the second growth speed, namely executing the following step 1023; and when the initial growth result is judged to meet the second preset condition, the growth is still carried out according to the first growth speed.
It should be noted that, the execution main body periodically determines whether the initial growth result meets a second preset condition, for example, in order to more accurately determine the time from the stage of growth at the first growth speed to the stage of growth at the second growth speed, the period may be set to correspond to the first preset iteration speed, that is, the time required for the seed point to execute the first growth algorithm once at the first preset iteration speed; alternatively, in order to further reduce the time for tissue growth, the period may be set to a corresponding time length after several tissue growths at the first growth rate. The present invention is not particularly limited to this period.
1023. And when detecting that the initial growth result meets a second preset condition, calling a growth algorithm according to a second preset iteration speed, and controlling the initial growth result to grow according to the second growth speed to obtain a first growth result.
It should be noted that, after the tissue grows to a certain degree, that is, the tissue growing in the tissue growth process is closer to the complete structure stage of the tissue or grows to the fine structure stage of the tissue, overgrowth (outgrowth) is more easily generated, and some other tissues grow out, for example, in the blood vessel growth process, the initial growth stage of the blood vessel is the growth of the main blood vessel, and the structure of the main blood vessel is coarse, so that the outgrowth is not easy to occur in the stage, while when the capillary blood vessel is extracted, that is, when the capillary blood vessel is grown, because the structure of the capillary blood vessel is fine, if the growth is performed according to a larger growth speed, the outgrowth of the tissue is easily generated, and when the outgrowth occurs, the structure of the outgrowth tissue is larger. Therefore, in order to alleviate the occurrence of this phenomenon, when the tissue grows to a certain stage, it is necessary to reduce the growth rate thereof, that is, to set the second growth rate to be lower than the first growth rate in order to control the occurrence of overgrowth of the tissue.
In different tissue growth periods, call first growth algorithm according to different frequencies to control the tissue to grow according to corresponding growth rate in different growth stages, compare the mode that adopts single growth rate control tissue growth, the technical scheme that this embodiment provided can be according to the growth rate of demand control tissue, thereby can improve tissue growth rate, reduce the time that the tissue grows, can effectively avoid growing simultaneously and spill over.
It should be noted that, because the overflowed growth phenomenon mainly occurs in a stage in which the grown tissue is closer to the complete structure of the tissue or a stage in which the grown tissue grows to a fine structure of the tissue, and the overflowed growth phenomenon does not generally occur in the process of growing at the first growth speed, and the structure of the tissue grown at this stage grows well, when the growth rollback is executed, in order to reduce the waiting time for continuing the growth of the rolled-back growth state to obtain the final complete tissue, when the rollback is executed, the first growth result is rolled back to the specified growth result corresponding to the process in which the initial growth result is grown at the second growth speed, when the second growth result corresponding to the specified state to which the first growth result is rolled back is executed, wherein the specified result is the second growth result.
Further, in order to reduce the occurrence of overgrowth in the tissue growth process, another implementation manner is provided in the embodiment of the present invention, as shown in fig. 4, step 1023 specifically includes:
201. and periodically detecting whether a growth ending instruction is received or not in the process that the initial seed point grows in the growth process.
It should be noted that the setting principle of the detection period is similar to the principle of the period setting in step 1022, that is, the time length required for executing the first growth algorithm once can be set as a detection period; alternatively, a period corresponding to one detection duration after performing the growth algorithm several times may be set. Therefore, the present invention does not limit the setting of the period of the detection.
202. And if detecting that a growth ending instruction is received, ending the tissue growth to obtain the first growth result.
The user inputs the designated operation through the medical equipment and informs the execution main body that the tissue growth can be stopped, so that the execution main body is triggered to generate a corresponding growth ending instruction, the tissue growth is stopped in response to the growth ending instruction, the growth result of the tissue with the growth stopped is obtained, and the growth result is stored to the designated position.
It is supplementary noted that, when the executing entity detects that the growth ending instruction is not received, the executing entity continues to execute the tissue growth on the first growth result at the second growth speed until the terminal receives a specified operation input by the user or a growth ending instruction sent by other equipment, thereby terminating the tissue growth.
Further, based on the difference of the set second preset condition, the embodiment of the present invention provides two implementation manners for the implementation of step 1022,
the first mode, when the second preset condition is the area of the growing tissue, as shown in fig. 5, specifically includes:
301A, obtaining an initial growth area corresponding to the initial growth result.
302A, comparing whether the initial growth area exceeds a preset area threshold value.
303A, if the initial growth area exceeds the preset area threshold value by comparison, determining that the initial growth result meets a second preset condition.
304A, if the initial growth area is compared and the area exceeding threshold value is not preset, determining that the initial growth result does not meet a second preset condition.
In a second manner, when the set second preset condition is a growth time, as shown in fig. 6, the method specifically includes:
301B, obtaining the initial growth time corresponding to the initial growth result.
302B, comparing whether the initial growth time reaches a preset growth time threshold value.
303B, if the initial growth time is compared to reach a preset growth time threshold, determining that the initial growth result meets a second preset condition.
304B, if the initial growth area does not reach the preset growth time threshold value by comparison, determining that the initial growth result does not meet a second preset condition.

When the first growth result is judged to meet the first preset condition, that is, the phenomenon of growth overflow occurs in the first growth result, the second obtaining unit 43 is triggered to obtain the specified operation; when the first growth result is judged not to meet the first preset condition, namely the phenomenon of growth overflow does not occur in the first growth result, the second obtaining unit does not need to obtain the specified operation. Or, an instruction or action directly input to the execution subject by the user triggers the execution subject to acquire the specified operation.

In order to enable other application scenarios in the medical device to implement rollback operation, an embodiment of the present invention provides another control method, which is applicable to the medical device, based on the concept of the control method described above, where a flowchart of the control method is as shown in fig. 8, and specifically includes:
601. and acquiring the corresponding relation between the data information of the operation object from the initial state to the current state and the progress bar.
Each state of the operation object corresponds to one type of data information, and it can be understood that each state of the operation object has a corresponding relationship with the progress bar.
602. And acquiring a rollback operation of the progress bar.
Wherein the rollback operation comprises dragging, sliding or clicking the progress bar to cause the progress of the operation to rollback.
603. And controlling the operation object to retreat from the current state to the specified state according to the corresponding relation and the retreat operation.
The designated state comprises the operation object which is returned to any previous state from the current state, and also comprises the initial state. For example, after the image is enlarged, the image is gradually reduced from the enlarged current state by a retraction operation of the progress bar, and when the image reaches the designated state, the progress bar is released, the retraction operation is terminated, and the image is reduced to the designated state. The designated state is any state between the initial state and the current state, or may be the initial state.
According to the technical scheme provided by the embodiment of the invention, the corresponding relation between the data information of the operation object from the initial state to the current state and the progress bar is set, so that the operation object can be returned from the current state to any specified state required by a user by operating the progress bar.
