Description

Technical Field

[0001] The present invention relates to the field of ultrasonic imaging technology, and in particular to an image playback and storage method, system, device and medium of an ultrasonic system. Background Art

[0002] When adjusting the front-end parameters of the ultrasound system, such as detection depth, line density, speed scale, sampling line, etc., there are incompatibilities in the data and parameters before and after the adjustment. Therefore, most ultrasound systems need to clear the playback area after adjusting the front-end parameters. In some special clinical scenarios, such as prenatal examinations and neonatal examinations, doctors cannot ensure the limb movements of the subjects in these scenarios, and each test requires a certain amount of data support. When using a set of front-end parameters, the image data needs to be cleared after adjusting the front-end parameters. In the existing ultrasound system mode, after moving the sampling line and sampling gate, the spectrum needs to be refreshed. Doctors must first freeze the previous image data if they want to obtain it, and then store the required data. The stored files are fragmented, and it is difficult for doctors to obtain enough data within a limited time, and the inspection efficiency is very low.

[0003] In the related technology, there is a mismatch between data and parameters in the existing ultrasound system before and after adjusting the parameters. The mismatch between data and parameters will lead to the inability to correctly image. Therefore, the existing ultrasound system needs to clear the playback area after adjusting the parameters to achieve normal imaging, resulting in low efficiency of detection by the existing ultrasound system. Summary of the invention

[0004] In view of this, the present invention provides an image playback and storage method, system, device and medium for an ultrasound system to solve the problem of incompatibility between data and parameters in existing ultrasound systems, resulting in the need to clear the playback area before and after adjusting parameters.

[0005] In a first aspect, the present invention provides an image playback and storage method for an ultrasound system, which is applied to software of the ultrasound system, and the method comprises:

[0006] Determining front-end parameters used in ultrasound system front-end imaging calculations;

[0007] Perform parameter calculation on the front-end parameters, obtain the front-end parameter calculation results and determine the front-end parameter versions corresponding to the front-end parameters;

[0008] Send the front-end parameter calculation result and the front-end parameter version to the field programmable gate array, so that the field programmable gate array controls and calculates the image data corresponding to the front-end parameter calculation result based on the front-end parameter calculation result, and uses the front-end parameter version as the data version corresponding to the image data, and uploads it to the software together with the image data;

[0009] Receiving image data, parsing the image data, and obtaining the image data and a data version corresponding to the image data;

[0010] Through the parameter distribution mechanism, the data version is used to determine the version parameters corresponding to the data version and pre-process the image data;

[0011] The pre-processed image data and the front-end parameters corresponding to the image data are stored in the playback area of ​​the ultrasound system to realize image playback and storage of the ultrasound system.

[0012] In the present invention, by determining the front-end parameters used in the front-end imaging calculation of the ultrasound system, using the software of the ultrasound system to calculate and generate the front-end parameter version corresponding to the front-end parameters, the front-end parameter version is transmitted to the FPGA of the ultrasound system as an identifier, so that the image data generated by the FPGA and the front-end parameter version can be matched one by one, and the image data and the front-end parameters are bound to each other, so that the image data and multiple sets of front-end parameters can coexist. The image data and the corresponding front-end parameters are stored in the playback area of ​​the ultrasound system, so that when the front-end parameters change, the corresponding front-end parameters can be obtained from the playback area according to the binding relationship between the front-end parameters and the image data, avoiding the mismatch between the parameters and the data. The playback area is cleared before and after the parameter adjustment. Using the image playback and storage method of the ultrasound system in clinical application scenarios such as prenatal examinations and neonatal examinations can obtain sufficient data at one time, greatly improving the inspection efficiency.

[0013] In an optional embodiment, the method further includes:

[0014] After the front-end parameters are adjusted, the front-end parameter version is incremented after the front-end parameter calculation to obtain a data structure bound to the updated front-end parameters and the front-end parameter version corresponding to the front-end parameters, and then returns to the step of sending the front-end parameter calculation results and the front-end parameter version to the field programmable gate array.

[0015] In this method, after the front-end parameters are adjusted, the front-end parameter version is incremented and sent to the FPGA before the front-end parameters are sent to the FPGA. This ensures that after the front-end parameter version is sent to the FPGA, the FPGA uses the front-end parameters sent this time to generate image data, thereby realizing one-to-one binding of different versions of image data and parameters, and then realizing playback and storage of different versions of image data. Image data with multiple sets of front-end parameters can be stored on the same video, avoiding the clearing of playback area data due to the inability of different versions of data to coexist.

[0016] In an optional implementation, the parameter distribution mechanism includes: dividing the front-end parameters into first front-end parameters being written, second front-end parameters being stored in the middle, and third front-end parameters being read based on the processing status;

[0017] The first front-end parameter is used to perform parameter linkage operation. After the parameter linkage is completed, the parameter is updated through the parameter distribution mechanism. The first front-end parameter is used to perform an update write operation on the second front-end parameter and write it into the second front-end parameter.

[0018] In this method, through the parameter distribution mechanism, the parameters in different time periods are distributed and processed accordingly based on the time period in which the front-end parameters are located, so as to facilitate the use of the parameter distribution mechanism to determine the front-end parameters corresponding to the image data, thereby realizing image playback and storage of the ultrasound system.

[0019] In an optional implementation, determining a version parameter corresponding to a data version includes:

[0020] Based on the data version, version mapping is performed on the second front-end parameter to obtain the second front-end parameter corresponding to the data version;

[0021] The second front-end parameter corresponding to the data version is transferred to the third front-end parameter to obtain the third front-end parameter corresponding to the data version.

[0022] In this method, the second front-end parameter is version mapped through the data version to obtain the second front-end parameter corresponding to the data version, and the second front-end parameter corresponding to the data version is transferred to the third front-end parameter being read to obtain the front-end parameter corresponding to the data version.

[0023] In an optional implementation, storing the pre-processed image data and the front-end parameters corresponding to the data version in a playback area of ​​the ultrasound system includes:

[0024] The pre-processed image data is associated with the front-end parameters corresponding to the data version using a mapping table to obtain the associated image data and the front-end parameters, and the associated image data and the front-end parameters associated with the image data are stored in a playback area of ​​the ultrasound system.

[0025] In this method, the image data and the front-end parameters are associated one by one by using a mapping table, and then transferred to the playback area of ​​the ultrasound system as the parameter and data source for subsequent frozen playback and image storage. Since frozen playback refers to traversing the data in the playback area to determine the data to be played back this time and the front-end parameters corresponding to the data, image post-processing is performed on the image data and front-end parameters after the one-to-one association, and frozen playback can be achieved without clearing the data playback area.

[0026] In a second aspect, the present invention provides an image playback and storage method for an ultrasound system, which is applied to a field programmable gate array of the ultrasound system, and the method comprises:

[0027] Receive the front-end parameter calculation results and the front-end parameter version sent by the software, the front-end parameter calculation results are the front-end parameters used by the software to determine the front-end imaging calculation of the ultrasound system, perform parameter calculation on the front-end parameters to obtain the front-end parameter calculation results, and the front-end parameter version is the front-end parameter version corresponding to the front-end parameters determined by the software after performing parameter calculation on the front-end parameters;

[0028] Based on the calculation results of the front-end parameters, control and calculate to obtain image data corresponding to the front-end parameters;

[0029] The front-end parameter version is used as the data version corresponding to the image data, and is uploaded to the software together with the image data, so that the software receives the image data, parses the image data, and obtains the image data and the data version corresponding to the image data; through the parameter distribution mechanism, the data version and the parameter distribution mechanism are used to determine the front-end parameters corresponding to the data version, and pre-process the image data; the pre-processed image data and the front-end parameters corresponding to the data version are stored in the playback area of ​​the ultrasound system to realize image playback and storage of the ultrasound system.

[0030] In the present invention, the front-end parameter version is transmitted to the FPGA as an identifier and the front-end parameter, and the FPGA generates corresponding image data according to the front-end parameter to achieve a one-to-one match between the image data generated by the FPGA and the front-end parameter version, and the image data and the front-end parameter version are transmitted back to the software, so that the software can achieve the coexistence of image data and multiple sets of front-end parameters by binding the image data with the front-end parameters. The image data and the corresponding front-end parameters are stored in the playback area of ​​the ultrasound system by the software, so that when the front-end parameters change, the corresponding front-end parameters can be obtained from the playback area according to the binding relationship between the front-end parameters and the image data, thereby avoiding the clearing of the playback area before and after the parameter adjustment caused by the mismatch between the parameters and the data.

[0031] In a third aspect, the present invention provides an image playback and storage system for an ultrasound system, the system comprising: software and a field programmable gate array for the ultrasound system;

[0032] The software determines the front-end parameters used in the front-end imaging calculation of the ultrasound system; performs parameter calculation on the front-end parameters, obtains the front-end parameter calculation results and determines the front-end parameter versions corresponding to the front-end parameters; sends the front-end parameter calculation results and the front-end parameter versions to the field programmable gate array;

[0033] The field programmable gate array receives the front-end parameter calculation results and the front-end parameter version issued by the software; based on the front-end parameter calculation results, controls and calculates to obtain image data corresponding to the front-end parameters; uses the front-end parameter version as the data version corresponding to the image data, and uploads it to the software together with the image data;

[0034] The software receives image data, parses the image data, obtains the image data and the data version corresponding to the image data; uses the data version through a parameter distribution mechanism to determine the version parameters corresponding to the data version, and pre-processes the image data; stores the pre-processed image data and the front-end parameters corresponding to the image data into a playback area of ​​the ultrasound system to realize image playback and storage of the ultrasound system.

[0035] In the present invention, since each piece of data needs to be supported by corresponding front-end parameters to process and obtain image data, a set of data and front-end parameter binding protocols are formulated for the software and FPGA in the image playback and storage system of the ultrasound system, and the mutual correspondence between the front-end parameters and the data is bound, so that the image data and the front-end parameter versions generated by the FPGA can be matched one by one, and the image data and the front-end parameters are bound in a way that the image data and the front-end parameters are bound, so that the image data and multiple sets of front-end parameters can coexist. The software stores the image data and the corresponding front-end parameters in the playback area of ​​the ultrasound system, so that when the front-end parameters change, the corresponding front-end parameters can be obtained from the playback area according to the binding relationship between the front-end parameters and the image data, avoiding the mismatch between the parameters and the data. The playback area is cleared before and after the parameter adjustment. Using the image playback and storage method of the ultrasound system in clinical application scenarios such as prenatal examinations and neonatal examinations can obtain enough data at one time, greatly improving the inspection efficiency.

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0045] In related technologies, in some special clinical scenarios, such as prenatal examinations and neonatal examinations, doctors cannot ensure the physical movements of the subjects in these scenarios, and each test requires a certain amount of data support. When using a set of front-end parameters, the image data needs to be cleared after adjusting the front-end parameters. In the existing ultrasound system mode, after moving the sampling line and sampling the gate, the spectrum needs to be refreshed. Doctors must first freeze the previous image data and then store the required data. The stored files are fragmented. Therefore, the ultrasound system needs to clear the playback area after adjusting the front-end parameters. It is difficult for doctors to obtain enough data within a limited time, and the inspection efficiency is very low.

[0046] To solve the above problems, an embodiment of the present invention provides an image playback and storage method for an ultrasound system, which is used in an image playback and storage system for an ultrasound system. In the following method embodiments, the execution subject is an image playback and storage system for an ultrasound system as an example for explanation. The image playback and storage system for an ultrasound system in this embodiment is suitable for use in a scenario where, in an ultrasound imaging scenario, the mismatch and incompatibility between ultrasound system parameters and data leads to the need to clear the data after adjusting the front-end parameters. The image playback and storage system for an ultrasound system provided by the present invention, since each piece of data needs to be supported by corresponding front-end parameters to process the image data, a set of data and front-end parameter binding protocols is formulated for the software and FPGA in the image playback and storage system of the ultrasound system, and the mutual correspondence between the front-end parameters and the data is bound, so that the image data generated by the FPGA and the front-end parameter versions can be matched one by one, and the image data and the front-end parameter binding method are adopted to realize the coexistence of image data and multiple sets of front-end parameters. The image data and the corresponding front-end parameters are stored in the playback area of ​​the ultrasound system through software, so that when the front-end parameters change, the corresponding front-end parameters can be obtained from the playback area according to the binding relationship between the front-end parameters and the image data, avoiding the need to clear the playback area before and after parameter adjustment due to the mismatch between the parameters and the data. Using the image playback and storage method of the ultrasound system in clinical application scenarios such as prenatal examinations and neonatal examinations can obtain sufficient data at one time, greatly improving the inspection efficiency.

[0047] According to an embodiment of the present invention, an embodiment of an image playback and storage method of an ultrasound system is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in an image playback and storage system of the ultrasound system, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0048] Figure 1 FIG. 4 is a schematic diagram of the structure of an image playback and storage system of an ultrasound system according to an embodiment of the present invention. Figure 1 As shown, the image playback and storage system of the ultrasound system includes: ultrasound system software 1 and a field programmable gate array 2. Figure 2 is an interactive schematic diagram of an image playback and storage system of an ultrasound system according to an embodiment of the present invention. In this embodiment, an image playback and storage method of an ultrasound system is provided, which can be used in the image playback and storage system of the ultrasound system, such as Figure 2 As shown, the software is used to execute steps S101 to S106, and the field programmable gate array is used to execute steps S201 to S203.

[0049] Step S101, determining front-end parameters used in front-end imaging calculation of an ultrasound system.

[0050] Step S102, performing parameter calculation on the front-end parameters, obtaining the front-end parameter calculation results and determining the front-end parameter versions corresponding to the front-end parameters.

[0051] In one example, the front-end parameter calculation results can be generated by performing linkage calculation on the front-end parameters, and the front-end parameter version can be generated by version auto-incrementing.

[0052] Step S103: Send the front-end parameter calculation result and the front-end parameter version to the field programmable gate array.

[0053] Step S201, receiving the front-end parameter calculation result and the front-end parameter version issued by the software.

[0054] Step S202: Based on the calculation result of the front-end parameters, control and calculate to obtain image data corresponding to the front-end parameters.

[0055] Step S203: The front-end parameter version is used as the data version corresponding to the image data and uploaded to the software together with the image data.

[0056] Step S104, receiving the image data, parsing the image data, and obtaining the image data and a data version corresponding to the image data.

[0057] Step S105 , using the data version through the parameter distribution mechanism, determining the version parameters corresponding to the data version, and pre-processing the image data.

[0058] Step S106, storing the pre-processed image data and the front-end parameters corresponding to the image data into the playback area of ​​the ultrasound system to realize image playback and storage of the ultrasound system.

[0059] In one example, since each piece of data needs corresponding parameters as a support for the ultrasound system to process and obtain image data, it is necessary to formulate a set of data and parameter binding protocols, which can bind the corresponding relationship between parameters and data. The data and front-end parameters are bound in such a way that the data and parameters can be matched one by one. The front-end parameters are the parameters used in the front-end imaging calculations of the ultrasound system. Different system solutions and processing procedures will have different definitions of the front-end parameters. Taking the B mode as an example, the front-end parameters include depth, frequency, number of points, number of lines, spatial composite gear, angle, number of focal points, number of beams, etc., all of which are front-end parameters. The front-end parameters are not limited in the present invention.

[0060] Specifically, the mutual correspondence between the parameters and the data is constructed including: through the interaction between the software and the FPGA. Among them, the FPGA is responsible for some underlying controls in the ultrasound system and the transmission and reception of the probe, high-voltage switch control, image data generation and some simple and complicated calculations, data upload, etc., which are slightly different according to the system scheme, and the FPGA is not limited in the present invention. After the software calculates the parameters, it will calculate a series of front-end parameters, and send these front-end parameters to the FPGA; the FPGA will perform a series of controls and calculations according to the front-end parameters sent by the software, generate image data, and finally upload the image data to the software. FPGA acts as a bridge between the front-end parameters and data. After the software completes the parameter calculation, when sending the front-end parameters to the FPGA, the front-end parameter version corresponding to the front-end parameters needs to be sent to the FPGA as a mark of this group of front-end parameters. When the FPGA uses this group of front-end parameters to generate image data, the front-end parameter version is bound to the generated image data, and the front-end parameter version and the generated image data are uploaded to the software together, and the version of the image data is determined. The specific binding time and binding method are as follows: after the software sends parameters and parameter versions to the FPGA, the FPGA uses the parameters sent by the software to generate image data and uploads it to the software for binding.

[0061] Specifically, the process of adjusting the front-end parameters may include: after the front-end parameters are calculated, the front-end parameter version corresponding to the front-end parameters is incremented, the front-end parameters and the front-end parameter version are sent to the FPGA, the FPGA generates image data through the front-end parameters, and the image data is uploaded to the software together with the corresponding front-end parameter version as image data and the corresponding data version. After receiving the image data, the software parses the image data and the corresponding data version, and when performing pre-processing, finds the front-end parameters corresponding to the front-end parameter version through the data version and parameter distribution mechanism, and enters the pre-processing; after the pre-processing is completed, the pre-processed data and the corresponding front-end parameters are stored in the playback area, and the mapping table is used to associate the data and the front-end parameters one by one, as the parameter and data source for subsequent frozen playback and image storage.

[0062] The image playback and storage system of the ultrasound system provided in this embodiment requires corresponding front-end parameters as support to process and obtain image data. Therefore, a set of data and front-end parameter binding protocols are formulated for the software and FPGA in the image playback and storage system of the ultrasound system, and the mutual correspondence between the front-end parameters and the data is bound, so that the image data and the front-end parameter versions generated by the FPGA can be matched one by one. The image data and the front-end parameters are bound to achieve the coexistence of image data and multiple sets of front-end parameters. The image data and the corresponding front-end parameters are stored in the playback area of ​​the ultrasound system by software, so that when the front-end parameters change, the corresponding front-end parameters can be obtained from the playback area according to the binding relationship between the front-end parameters and the image data, avoiding the mismatch between the parameters and the data. The playback area is cleared before and after the parameter adjustment. Using the image playback and storage method of the ultrasound system in clinical application scenarios such as prenatal examinations and neonatal examinations can obtain enough data at one time, greatly improving the inspection efficiency.

[0063] In this embodiment, a method for replaying and storing images of an ultrasound system is provided, which can be used for the above-mentioned image replaying and storing system of the ultrasound system. Figure 3 FIG. 4 is a flow chart of an image playback and storage method of an ultrasound system according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0064] Step S301, determine the front-end parameters used by the ultrasound system front-end imaging calculation. Figure 2 Step S101 of the illustrated embodiment will not be described in detail here.

[0065] Step S302, perform parameter calculation on the front-end parameters, obtain the front-end parameter calculation results and determine the front-end parameter version corresponding to the front-end parameters. Figure 2 Step S102 of the illustrated embodiment will not be described in detail here.

[0066] Step S303, the front-end parameter calculation result and the front-end parameter version are sent to the field programmable gate array, so that the field programmable gate array controls and calculates the image data corresponding to the front-end parameter calculation result based on the front-end parameter calculation result, and uses the front-end parameter version as the data version corresponding to the image data, and uploads it to the software together with the image data. For details, please refer to Figure 2 Step S103 of the illustrated embodiment will not be described in detail here.

[0067] Step S304: Receive image data, parse the image data, and obtain the image data and the data version corresponding to the image data. Figure 2 Step S101 of the illustrated embodiment will not be described in detail here.

[0068] Step S305 , using the data version through the parameter distribution mechanism, determining the version parameters corresponding to the data version, and pre-processing the image data.

[0069] Specifically, the parameter distribution mechanism includes: dividing the front-end parameters into the first front-end parameters being written, the second front-end parameters being stored in the middle and the third front-end parameters being read based on the processing status; the first front-end parameters are used to perform parameter linkage operations, and after the parameter linkage is completed, the parameters are updated through the parameter distribution mechanism, and the first front-end parameters are used to update and write the second front-end parameters into the second front-end parameters.

[0070] The above step S305 includes:

[0071] Step S3051: Based on the data version, version mapping is performed on the second front-end parameter to obtain the second front-end parameter corresponding to the data version.

[0072] Step S3052: transfer the second front-end parameter corresponding to the data version to the third front-end parameter to obtain the third front-end parameter corresponding to the data.

[0073] In one example, adjusting the data of the playback area according to the adjusted front-end parameters in the following manner may include:

[0074] Adjust the front-end parameters, and after the front-end parameter calculation, the parameter version will be automatically increased. At this time, the parameters and parameter versions will be sent to the FPGA. The FPGA generates image data through the parameters, and uploads it to the software together with the corresponding parameter version as image data and the corresponding data version. After receiving the image data, the software parses the data and the corresponding data version. When performing pre-processing, the corresponding version of the parameters is found through the data version and parameter distribution mechanism, and enters the pre-processing. The pre-processing includes black hole filling, multi-focus stitching, compounding, line smoothing, frame correlation, etc. The steps included in the pre-processing vary according to different system solutions and are not limited in the present invention. After the pre-processing is completed, the pre-processed data and the corresponding front-end parameters are stored in the playback area, and a mapping table is used to associate the data and parameters one by one as the parameters and data source for subsequent frozen playback and image storage. Among them, a mapping table is used to store the parameter version number and the corresponding specific parameters. After the uploaded data is parsed, the data version information can be obtained. The data version information is used as an association, and all parameters corresponding to the data version can be found in the above mapping table.

[0075] First, after the pre-processing is completed, the pre-processed data and the parameters used in the pre-processing need to be transferred to the playback area. Among them, frozen playback mainly traverses the data in the playback area, obtains the data and the corresponding parameters that need to be replayed this time, and performs image post-processing to achieve frozen playback. There are two types of image storage, real-time storage and frozen storage. Real-time storage means that in real time, press forward or backward storage to retrieve data and corresponding parameters from the playback area, and store the retrieved data and parameters in a file; frozen storage is to retrieve the data and parameters in the playback area in a frozen state and store them in a file. Both storage methods are dependent on the data and parameters in the playback area. The data and parameters in the playback area have been cached during pre-processing. Frozen playback and image storage only need to determine the corresponding data and parameters from the playback area.

[0076] Specifically, the parameter distribution mechanism only needs to divide the parameters into three processes: the parameters being written, the parameters being stored in the middle, and the parameters being read. The parameters being written are for parameter linkage operations. After the parameter linkage is completed, the parameters are updated and written to the parameters stored in the middle. The pre-processing obtains the data version number through data analysis, and passes the data version number to the parameter distribution module. The corresponding version of the parameters is found in the parameters stored in the middle, and the parameters are moved to the parameters being read. At this time, the parameters corresponding to the data can be obtained. After the pre-processing is completed, the parameters corresponding to the data are verified and transferred, and stored in the playback area together. The post-processing obtains data from the playback area, finds the corresponding version of the parameters in the playback area according to the data version, and performs image post-processing, and finally displays the image.

[0077] Step S306, storing the pre-processed image data and the front-end parameters corresponding to the image data into the playback area of ​​the ultrasound system to achieve image playback and storage of the ultrasound system. Figure 1 Step S106 of the illustrated embodiment will not be described in detail here.

[0078] Step S307, after front-end parameter calculation, the front-end parameter version is incremented to obtain a data structure in which the updated front-end parameter is bound to the front-end parameter version corresponding to the front-end parameter, and returns to the step of sending the front-end parameter calculation result and the front-end parameter version to the field programmable gate array.

[0079] In one example, the parameter version increment means that when the parameters are sent to the FPGA this time, the parameter version is incremented and the result is sent to the FPGA. After the parameter version is sent to the FPGA, the FPGA uses the parameters sent this time to generate image data, and the data version is the parameter version accompanying the parameters sent this time.

[0080] In this method, after the front-end parameters are adjusted, the front-end parameter version is incremented and sent to the FPGA before the front-end parameters are sent to the FPGA. This ensures that after the front-end parameter version is sent to the FPGA, the FPGA uses the front-end parameters sent this time to generate image data, thereby realizing one-to-one binding of different versions of image data and parameters, and then realizing playback and storage of different versions of image data. Image data with multiple sets of front-end parameters can be stored on the same video, avoiding the clearing of playback area data due to the inability of different versions of data to coexist.

[0081] The image playback and storage method of the ultrasound system provided in this embodiment determines the front-end parameters used for the front-end imaging calculation of the ultrasound system, uses the software of the ultrasound system to calculate and generate the front-end parameter version corresponding to the front-end parameters, and transmits the front-end parameter version as an identifier to the FPGA of the ultrasound system, so that the image data generated by the FPGA and the front-end parameter version can be matched one by one, and the image data and the front-end parameters are bound in a way to achieve the coexistence of image data and multiple sets of front-end parameters. The image data and the corresponding front-end parameters are stored in the playback area of ​​the ultrasound system, so that when the front-end parameters change, the corresponding front-end parameters can be obtained from the playback area according to the binding relationship between the front-end parameters and the image data, avoiding the clearing of the playback area before and after the parameter adjustment caused by the mismatch between the parameters and the data. Using the image playback and storage method of the ultrasound system in clinical application scenarios such as prenatal examinations and neonatal examinations can obtain sufficient data at one time, greatly improving the inspection efficiency. After the front-end parameters are adjusted, before the front-end parameters are sent to the FPGA, the front-end parameter version is incremented and sent to the FPGA, ensuring that after the front-end parameter version is sent to the FPGA, the FPGA uses the front-end parameters sent this time to generate image data, realizing one-to-one binding of different versions of image data and parameters, thereby realizing playback and storage of different versions of image data, and multiple sets of image data of front-end parameters can be stored on the same video, avoiding the clearing of playback area data due to the inability of different versions of data to coexist. Through the parameter distribution mechanism, the parameters in different time periods are distributed and processed accordingly based on the time period in which the front-end parameters are located, so as to facilitate the use of the parameter distribution mechanism to determine the front-end parameters corresponding to the image data, thereby realizing image playback and storage of the ultrasound system. Through the data version, the second front-end parameter is version mapped to obtain the second front-end parameter corresponding to the data version, and the second front-end parameter corresponding to the data version is transferred to the third front-end parameter being read, so as to obtain the front-end parameter corresponding to the data version. By using the mapping table to associate the image data with the front-end parameters one by one, and transfer them to the playback area of ​​the ultrasound system as the parameter and data source for subsequent frozen playback and image storage. Since frozen playback refers to traversing the data in the playback area to determine the data that needs to be played back this time and the front-end parameters corresponding to the data, image post-processing is performed on the image data and front-end parameters after one-to-one association. Frozen playback can be achieved without clearing the data playback area.
