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 front-end parameters of an ultrasound system, such as detection depth, line density, velocity scale, and sampling line, there are incompatibilities in the data and parameters before and after the adjustment. Therefore, most ultrasound systems require clearing 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, and each examination 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. If the doctor wants to obtain the previous image data, he must first freeze it and then store the required data. The stored files are fragmented, making it difficult for the doctor to obtain enough data within a limited time, and the examination efficiency is very low.

[0003] In the related art, there is a mismatch between data and parameters in the existing ultrasound system before and after parameter adjustment. The mismatch between data and parameters will lead to incorrect imaging. 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, which requires clearing 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] Determine 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 version corresponding to the front-end parameters;

[0008] Sending the front-end parameter calculation results 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 results based on the front-end parameter calculation results, 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 to obtain the image data and a data version corresponding to the image data;

[0010] Through a parameter distribution mechanism, the data version is used to determine a version parameter corresponding to the data version, and the image data is preprocessed;

[0011] The preprocessed image data and the front-end parameter corresponding to the image data are stored in a playback area of the ultrasound system to realize image playback and storage of the ultrasound system.

[0012] In the present application, by determining the front-end parameter used by the front-end imaging calculation of the ultrasound system, the front-end parameter version corresponding to the front-end parameter is generated by using the software of the ultrasound system, and the front-end parameter version is transmitted into 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 parameter are bound in a way, realizing the coexistence of image data and multiple front-end parameters. The image data and the corresponding front-end parameter are stored in the playback area of the ultrasound system, so that when the front-end parameter changes, the corresponding front-end parameter can be obtained from the playback area according to the binding relationship between the front-end parameter and the image data, avoiding the emptying of the playback area caused by the mismatch between the parameters and the data before and after the adjustment of the parameters. The image playback and storage method of the ultrasound system is used in the clinical application scene of antenatal examination and neonatal examination, and enough data can be obtained at one time, greatly improving the examination efficiency.

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

[0014] After the front-end parameter is adjusted, the front-end parameter version is incremented after the front-end parameter calculation, and the data structure of the updated front-end parameter and the front-end parameter corresponding to the front-end parameter version is obtained, and returned to the step of issuing the front-end parameter calculation result and the front-end parameter version to the field programmable gate array.

[0015] In this way, after the front-end parameter is adjusted, the front-end parameter version is incremented and issued to the FPGA before the front-end parameter is issued to the FPGA this time, so that after the front-end parameter version is issued to the FPGA, the FPGA generates image data using the front-end parameter issued this time, realizes one-to-one binding of image data and parameters of different versions, and further realizes playback and storage of image data of different versions, so that multiple sets of image data of front-end parameters can be stored on the same video, avoiding emptying the playback area data due to the coexistence of different versions of data.

[0016] In an optional embodiment, the parameter distribution mechanism comprises: dividing the front-end parameter into a first front-end parameter being written, a second front-end parameter being stored and a third front-end parameter being read based on a processing state;

[0017] The first front-end parameter is used for parameter linkage operation, and after the parameter linkage ends, the parameter is updated through the parameter distribution mechanism, the second front-end parameter is updated and written into the second front-end parameter by using the first front-end parameter.

[0018] In this way, through the parameter distribution mechanism, the parameters in different time periods are distributed based on the time period of the front-end parameter, so as to facilitate the determination of the corresponding front-end parameter of the image data by using the parameter distribution mechanism, and then realize the image playback and storage of the ultrasonic system.

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

[0022] In this way, the second front-end parameter is version mapped based on 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 stored into the third front-end parameter being read to obtain the front-end parameter corresponding to the data version.

[0023] In an optional embodiment, the pre-processed image data and the front-end parameter corresponding to the data version are stored into the playback area of the ultrasonic system, comprising:

[0025] In this way, the image data and the front-end parameter are associated one by one by using the mapping table and are stored into the playback area of the ultrasonic system as the parameter and data source for subsequent frozen playback and image storage. Since the frozen playback refers to the data in the playback area, the data to be played back this time and the front-end parameter corresponding to the data are determined, so that the image data and the front-end parameter associated one by one are subjected to image post-processing, and the data playback area does not need to be emptied, and the frozen playback can be realized.

[0026] In a second aspect, the application provides an image playback and storage method of an ultrasonic system, applied to a field programmable gate array of the ultrasonic system, comprising:

[0028] Based on the front-end parameter calculation result, the image data corresponding to the front-end parameter is controlled and calculated;

[0029] The front-end parameter version is used as a data version corresponding to the image data, and the image data is uploaded to the software in combination to enable the software to receive the image data, analyze the image data, obtain the image data and the data version corresponding to the image data, determine the front-end parameter corresponding to the data version through a parameter distribution mechanism, and pre-process the image data; and the pre-processed image data and the front-end parameter corresponding to the data version are stored in a playback area of the ultrasonic system to realize image playback and storage of the ultrasonic system.

[0030] In the present application, the front-end parameter version is used as an identifier and is transmitted into the FPGA together with the front-end parameter, the FPGA generates corresponding image data according to the front-end parameter to realize one-to-one matching between the image data generated by the FPGA and the front-end parameter version, the image data and the front-end parameter version are transmitted back to the software to enable the software to realize coexistence of the image data and multiple sets of front-end parameters through the binding of the image data and the front-end parameter, and the image data and the corresponding front-end parameter are stored in the playback area of the ultrasonic system by the software, so that when the front-end parameter changes, the corresponding front-end parameter can be obtained from the playback area according to the binding relationship between the front-end parameter and the image data, and the emptying of the playback area before and after parameter adjustment caused by mismatching between the parameter and the data is avoided.

[0031] In a third aspect, the present application provides an image playback and storage system of an ultrasonic system, which comprises: software of the ultrasonic system and a field programmable gate array;

[0032] The software determines a front-end parameter used for front-end imaging calculation of the ultrasonic system, performs parameter calculation on the front-end parameter to obtain a front-end parameter calculation result and determine a front-end parameter version corresponding to the front-end parameter, and transmits the front-end parameter calculation result and the front-end parameter version to the field programmable gate array;

[0033] The field programmable gate array receives the front-end parameter calculation result and the front-end parameter version transmitted by the software, controls and calculates image data corresponding to the front-end parameter based on the front-end parameter calculation result, and uploads the front-end parameter version to the software in combination with the image data as a data version corresponding to the image data;

[0044] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some 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 skilled in the art without creative labor fall within the protection scope of the present application.

[0045] In the related art, in some special clinical scenarios, such as prenatal examination and neonatal detection, doctors cannot ensure the limb movement of the examination object in these scenarios, and each detection needs a certain amount of data support. When using a set of front-end parameters, the image data needs to be emptied after adjusting the front-end parameters. In the mode of the existing ultrasound system, the frequency spectrum needs to be refreshed after moving the sampling line and the sampling gate. Doctors want to obtain the previous image data must first freeze, then store the required data. The stored file is fragmented, so the ultrasound system needs to empty the playback area after adjusting the front-end parameters. Doctors are difficult to obtain sufficient data in a limited time, and the examination efficiency is very low.

[0046] To solve the above problems, the embodiment of the present application provides an image playback and storage method of an ultrasonic system, which is used in an image playback and storage system of the ultrasonic system. In the following method embodiment, the execution subject is taken as an example of the image playback and storage system of the ultrasonic system. The image playback and storage system of the ultrasonic system in the embodiment is suitable for the use scenario that the mismatch and incompatibility of the ultrasonic system parameters and data cause the need to empty the data after adjusting the front-end parameters in the scene of ultrasonic imaging. The image playback and storage system of the ultrasonic system is provided by the present application. Since each data needs to have corresponding front-end parameters as support 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 ultrasonic system, the mutual corresponding relationship between the front-end parameters and the data is bound, the image data and the front-end parameter version generated by the FPGA can be matched one by one, the image data and multiple sets of front-end parameters coexist in the way of binding the image data and the front-end parameters. The image data and the corresponding front-end parameters are stored in the playback area of the ultrasonic 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, and the emptying of the playback area before and after the parameter adjustment caused by the mismatch between the parameters and the data is avoided. The image playback and storage method of the ultrasonic system is used in the scene of clinical application such as antenatal examination and neonatal examination, and enough data can be obtained at one time, which greatly improves the examination efficiency.

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

[0048] Figure 1 FIG. 1 is a structural schematic diagram of an image playback and storage system of an ultrasonic system according to the embodiment of the present application. As shown in FIG. 1, the image playback and storage system of the ultrasonic system comprises software 1 of the ultrasonic system and a field programmable gate array 2. Figure 1 FIG. 2 is an interaction schematic diagram of the image playback and storage system of the ultrasonic system according to the embodiment of the present application. In the embodiment, an image playback and storage method of an ultrasonic system is provided, which can be used in the above-mentioned image playback and storage system of the ultrasonic system. As shown in FIG. 2, the software is used to execute steps S101 to S106, and the field programmable gate array is used to execute steps S201 to S203. Figure 2 Figure 2

[0049] Step S101, determine the front-end parameters used by the front-end imaging calculation of the ultrasonic system. ​​

[0050] Step S102, parameter calculation is performed on the front-end parameter to obtain a front-end parameter calculation result and determine a front-end parameter version corresponding to the front-end parameter.

[0051] In an example, the front-end parameter calculation result can be generated by performing linkage calculation on the front-end parameter, and the front-end parameter version can be generated by version self-increment.

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

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

[0054] Step S202, based on the front-end parameter calculation result, image data corresponding to the front-end parameter is controlled and calculated.

[0055] Step S203, the front-end parameter version is taken as a data version corresponding to the image data, and the image data is uploaded to the software.

[0056] Step S104, the image data is received, and the image data is parsed to obtain the image data and a data version corresponding to the image data.

[0057] Step S105, by using the data version, a version parameter corresponding to the data version is determined by a parameter distribution mechanism, and the image data is preprocessed.

[0058] Step S106, the preprocessed image data and the front-end parameter corresponding to the image data are stored in a playback area of the ultrasonic system to realize image playback and storage of the ultrasonic system.

[0059] In an example, since each data needs to have a corresponding parameter to support the ultrasonic system to process the image data, a set of data and parameter binding protocol needs to be formulated, which can bind the mutual corresponding relationship between the parameters and the data. By using the data and front-end parameter binding mode, the data and the parameter can be matched one by one. The front-end parameter is a parameter used for front-end imaging calculation of the ultrasonic system, and different system schemes and processing procedures will be different in the definition of the front-end parameter. Taking B mode as an example, the front-end parameter includes depth, frequency, point number, line number, spatial composite gear position, angle, focus number, beam number, etc., which all belong to the front-end parameter. The front-end parameter is not limited in the present application.

[0060] Specifically, the mutual correspondence between the construction parameters and the data includes: interaction between the software and the FPGA. Wherein, the FPGA is responsible for some bottom control in the ultrasonic system and the emission and reception of the probe, high-voltage switch control, image data generation and some simple and complex calculation, data uploading, etc. According to the system scheme, the FPGA is not limited in the application. After the software calculates the parameters, a series of front-end parameters will be calculated, and these front-end parameters will be issued to the FPGA. The FPGA will generate image data according to the front-end parameters issued by the software, and finally upload the image data to the software. As a bridge between the front-end parameters and the data, when the software completes the parameter calculation, the front-end parameter version corresponding to the front-end parameters is issued to the FPGA as a marker for 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 with the generated image data, and the front-end parameter version and the generated image data are uploaded to the software together, so as to determine the version of the image data. Wherein, the specific binding time and binding method are as follows: after the software issues the parameters and the parameter version to the FPGA, the FPGA generates image data using the parameters issued by the software and uploads the software to bind.

[0061] Specifically, the process of adjusting the front-end parameters can include: after the front-end parameter calculation, the front-end parameter version corresponding to the front-end parameters is incremented, the front-end parameters and the front-end parameter version are issued to the FPGA, the FPGA generates image data through the front-end parameters, and uploads the corresponding front-end parameter version to the software together, as the image data and the corresponding data version. After the software receives the image data, the image data and the corresponding data version are parsed, and in the pre-processing, the front-end parameters corresponding to the front-end parameter version are found through the data version and the parameter distribution mechanism, and the pre-processing is entered. 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 parameters and data source for subsequent frozen playback and image storage.

[0062] The image playback and storage system for an ultrasound system provided in this embodiment requires corresponding front-end parameters as support to process and obtain image data. Therefore, a data and front-end parameter binding protocol is developed for the software and FPGA in the ultrasound system's image playback and storage system. The corresponding relationship 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. By binding the image data and the front-end parameters, the coexistence of image data and multiple sets of front-end parameters is achieved. The image data and the corresponding front-end parameters are stored in the ultrasound system's playback area through software. When the front-end parameters change, the corresponding front-end parameters can be obtained from the playback area based on the binding relationship between the front-end parameters and the image data. This avoids the need to clear the playback area before and after parameter adjustment due to mismatches between the parameters and data. Using the image playback and storage method of the ultrasound system in clinical applications such as prenatal examinations and neonatal examinations can obtain sufficient data at one time, significantly improving examination efficiency.

[0063] In this embodiment, a method for replaying and storing images of an ultrasound system is provided, which can be used in the above-mentioned image replaying and storing system of the ultrasound system. Figure 3 FIG. 1 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 for front-end imaging calculations. Figure 2 Step S101 of the illustrated embodiment will not be described in detail here.

[0065] Step S302: Calculate 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: 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 can control and calculate the image data corresponding to the front-end parameter calculation result based on the front-end parameter calculation result, and use the front-end parameter version as the data version corresponding to the image data, and upload it to the software together with the image data. 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] In step S305, the image data is preprocessed by using the data version to determine the version parameter corresponding to the data version through the parameter distribution mechanism.

[0069] Specifically, the parameter distribution mechanism includes: dividing the front-end parameter into a first front-end parameter being written, a second front-end parameter being stored, and a third front-end parameter being read based on the processing state; the first front-end parameter is used for parameter linkage operation, and after the parameter linkage ends, the parameter is updated through the parameter distribution mechanism, and the second front-end parameter is updated and written by using the first front-end parameter.

[0070] The above step S305 includes:

[0071] In step S3051, the second front-end parameter is version-mapped based on the data version to obtain the second front-end parameter corresponding to the data version.

[0072] In step S3052, 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.

[0073] In an example, adjusting the data of the playback area according to the adjusted front-end parameter can include:

[0074] The front-end parameter is adjusted, the parameter version is incremented through front-end parameter calculation, at this time the parameter and the parameter version are issued to the FPGA. The FPGA generates image data through the parameter, and uploads the image data and the corresponding parameter version to the software as image data and corresponding data version. After the software receives the image data, the data and the corresponding data version are parsed, and when pre-processing, the corresponding version parameter is found through the data version and the parameter distribution mechanism, and the pre-processing is entered. The pre-processing includes black hole filling, multi-focus splicing, composition, line smoothing, frame correlation, etc. The steps included in the pre-processing are different according to different system schemes, which are not limited in the present application. After the pre-processing is completed, the pre-processed data and the corresponding front-end parameter are stored in the playback area, and a mapping table is used to associate the data and the parameter one by one as the parameter 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 parameter, and after the uploaded data is parsed, the data version information can be obtained, and the data version information is used as the association to find all parameters corresponding to the data version in the above mapping table.

[0075] First, after pre-processing is completed, the pre-processed data and the parameters used in pre-processing need to be stored in the playback area. Among them, the freeze playback mainly traverses the data in the playback area, obtains the data to be played back this time and the parameters corresponding to the data, and performs image post-processing, that is, the freeze playback can be realized. There are two kinds of image storage, real-time storage and freeze storage. Real-time storage refers to storing forward or backward in real time, obtaining data and corresponding parameters from the playback area, and storing the obtained data and parameters into a file; freeze storage refers to taking data and parameters from the playback area and storing them into a file under freeze. Both of these two storage methods depend on the data and parameters in the playback area. The data and parameters in the playback area have been cached during pre-processing, and freeze 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 used for parameter linkage operation, and after the parameter linkage operation is completed, the parameters are updated and written into the parameters being stored in the middle. The pre-processing obtains the data version number through data analysis, and the data version number is transmitted to the parameter distribution module. In the parameters being stored in the middle, the parameters corresponding to the version are found and 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 stored in the playback area. The post-processing obtains the data from the playback area, finds the parameters corresponding to the version in the playback area according to the data version, and performs image post-processing. Finally, the image is displayed.

[0077] Step S306, the pre-processed image data and the front-end parameters corresponding to the image data are stored in the playback area of the ultrasonic system to realize image playback and storage of the ultrasonic system. For details, please refer to Figure 1 The step S106 of the embodiment shown is not described here again.

[0078] Step S307, the front-end parameter version is incremented by one through front-end parameter calculation, and the data structure of the updated front-end parameter and the front-end parameter version corresponding to the front-end parameter is obtained, and returned to the step of issuing the front-end parameter calculation result and the front-end parameter version to the field programmable gate array.

[0079] In an example, the parameter version increment refers to incrementing the parameter version and issuing the result to the FPGA when the parameter is issued to the FPGA this time. After the parameter version is issued to the FPGA, the FPGA generates image data using the parameter issued this time. Then, the data version is the parameter version accompanied by the parameter issued this time.

[0080] In the mode, before the front-end parameter is issued to the FPGA this time, the version of the front-end parameter is increased and the version of the front-end parameter is issued to the FPGA after the adjustment of the front-end parameter, so that the FPGA generates image data using the front-end parameter issued this time after the version of the front-end parameter is issued to the FPGA, one-to-one binding of different versions of image data and parameters is realized, and then playback and storage of different versions of image data are realized, image data of multiple sets of front-end parameters can be stored on the same video, and the problem that the playback area data is emptied due to the fact that different versions of data cannot coexist is avoided.

[0081] The image playback and storage method of the ultrasonic system provided by the embodiment determines the front-end parameters used by the front-end imaging calculation of the ultrasonic system, calculates and generates a front-end parameter version corresponding to the front-end parameters by using the software of the ultrasonic system, and transmits the front-end parameter version to the FPGA of the ultrasonic 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. The image data and the front-end parameters are stored in the playback area of the ultrasonic 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, and the playback area is emptied before and after the parameter adjustment caused by the mismatch between the parameters and the data. The image playback and storage method of the ultrasonic system can be used in the clinical application scenarios such as prenatal examination and neonatal examination, and sufficient data can be obtained at one time, which greatly improves the examination efficiency. After the front-end parameters are adjusted, the front-end parameter version is incremented before the front-end parameters are transmitted to the FPGA, and the front-end parameter version is transmitted to the FPGA, so that the FPGA generates image data by using the front-end parameters transmitted this time after the front-end parameter version is transmitted to the FPGA, the image data and the parameters of different versions are one-to-one bound, and the playback and storage of image data of different versions are realized. The image data of multiple sets of front-end parameters can be stored on the same video, which avoids emptying the playback area data due to the incompatibility of data of different versions. Through the parameter distribution mechanism, the parameters in different time periods are distributed and processed based on the time period of the front-end parameters, so as to determine the corresponding front-end parameters of the image data by using the parameter distribution mechanism, and realize the image playback and storage of the ultrasonic system. The second front-end parameters are mapped by using the data version to obtain the second front-end parameters corresponding to the data version, and the second front-end parameters corresponding to the data version are stored in the third front-end parameters being read, so that the front-end parameters corresponding to the data version can be obtained. The image data and the front-end parameters are associated one by one by using the mapping table, and are stored in the playback area of the ultrasonic system as the parameter and data source for subsequent frozen playback and image storage. Since the frozen playback refers to the data in the playback area, the data to be played back this time and the front-end parameters corresponding to the data are determined, so that the image data and the front-end parameters associated one by one are subjected to image post-processing, the data playback area does not need to be emptied, and the frozen playback can be realized.
