The subject information of the subject P is further added to the data and stored in the data storage unit 6 (step S6).

  FIG. 4 is a flowchart showing a procedure for updating the analysis history data by analyzing the RAW data, and may be executed subsequent to step 6 in FIG. 3 or may be executed later.

  First, in response to a list display operation of the analysis history (or thumbnail) of the subject P of the operation unit 8, the RAW data analysis unit 52 includes the RAW to which the subject information of the subject P is added from the data storage unit 6. After searching the data and image data, the analysis history data corresponding to the RAW data, and the generation time and image data generation mode information corresponding to the image data (or the RAW data thumbnail and the analysis history data, and the image data (Thumbnail) is read from the data storage unit 6, a list of analysis histories (or thumbnails) is created and displayed on the display unit 7 (step S11).

  Here, FIG. 5 is a diagram showing an example of the analysis history list created by the RAW data analysis unit 52 and displayed on the display unit 7. The analysis history list 71 includes “ExamData”, “Type”, and “Size (MB)”, and columns of “Number of analysis”, “Analysis time”, and “Analysis comment” created in an updatable manner. Is done.

  In the column “ExamData” in the analysis history list 71, the generation time of each RAW data and image data to which the subject information of the subject P is added is displayed in units of year / month / day hour: minute: second. The

  Similarly, the type of RAW data and image data corresponding to each generation time in the column “ExamData” is displayed in the “Type” column. For example, “R” is displayed for RAW data, and “B” and “C” are displayed for B-mode image data of image data and color Doppler image data, respectively.

  Similarly, in the “Size (MB)” column, the data size of the RAW data and the image data corresponding to each generation time in the “ExamData” column is displayed in units of MB.

  Similarly, in the “number of analysis times” column, the number of times n of analysis of the RAW data corresponding to each generation time in the “ExamData” column is displayed.

  Similarly, in the “Analysis time” column, the time when the RAW data corresponding to each generation time in the “ExamData” column is analyzed is displayed in units of year / month / day hour: minute: second. When the number of times of analysis n is plural, the time for each analysis is displayed by the analysis time display operation of the operation unit 8.

  Finally, in the “analysis comment” column, a comment on the analysis data of the RAW data corresponding to each generation time in the “ExamData” column is displayed by a comment input operation of the operation unit 8.

  Thus, the analysis history list 71 including the analysis history data such as the generation time analysis count, analysis time, and comments for each RAW data can be displayed on the display unit 7.

  FIG. 6 is a diagram showing an example of a thumbnail list created by the RAW data analysis unit 52 and displayed on the display unit 7. The thumbnail list 72 corresponds to each generation time displayed in the column “ExamData” of the analysis history list 71, and includes a plurality of thumbnail areas 73 that display thumbnails of each RAW data and image data.

  The thumbnail area 73 includes a thumbnail display area 74 that displays thumbnails of each RAW data and image data, and an analysis history display area 75 that displays the analysis history data of RAW data and the type of image data.

  In the thumbnail display area 74, thumbnails added to the RAW data and the image data are displayed.

  In the case of thumbnails of RAW data, thumbnails useful for searching can be generated and displayed in the thumbnail display area 74. Here, the RAW data reproduction operation of the operation unit 8 causes the image data generation unit 51 and the RAW data analysis unit 52 to read out the selected RAW data from the data storage unit 6.

  Then, the image data generation unit 51 generates image data from the RAW data read from the data storage unit 6, and further, according to the thumbnail selection operation, thumbnails (image data useful for search selected from the image data). (Selected thumbnail) is generated and output to the RAW data analysis unit 52 together with the generation time of the selected thumbnail. The RAW data analysis unit 52 adds the selected thumbnail output from the image data generation unit 51 to the RAW data and stores it in the data storage unit 6.

  In this way, when a plurality of thumbnails such as an initial thumbnail and a selected thumbnail are included in the RAW data, thumbnails useful for search selected in advance from the operation unit 8 are displayed.

  In the analysis history display area 75, any number of analyzes corresponding to each generation time in the “ExamData” column of the analysis history list 71, an analysis time, a comment, and the like are set in advance from the operation unit 8. Analysis history data can be displayed.

  In this way, a selection thumbnail useful for searching RAW data can be added, and the thumbnail and analysis history data including the number of analyzes, analysis time, comments, and the like can be displayed in the thumbnail list 72.

  Next, for example, the generation time corresponding to the desired RAW data in the column “ExamData” of the analysis history list 71 displayed on the display unit 7 is selected and operated from the operation unit 8, and further analyzed to perform image / analysis. The RAW data analysis unit 52 of the data generation unit 5 reads the selected RAW data from the data storage unit 6. The RAW data analysis unit 52 performs analysis based on analysis conditions such as velocity image analysis, velocity change inclination analysis, strain analysis, and displacement image analysis using the RAW data, and then generates analysis data. It displays on the display part 7 (step S12 of FIG. 4).

  In addition, the RAW data analysis unit 52 adds the analysis time, the comment of the analysis data input from the operation unit 8 and the like to the analysis history data, and adds 1 to the number of analyzes n before the analysis to perform the analysis. The analysis history data of the RAW data is updated (step S13 in FIG. 4). Then, the RAW data is stored in the data storage unit 6 together with the updated analysis history data (step S14 in FIG. 4).

  Next, when the operator who has viewed the analysis data displayed on the display unit 7 analyzes another RAW data or performs an analysis operation under another analysis condition of the same RAW data (Yes in step S15 in FIG. 4). Return to step S11. If the RAW data analysis operation is not performed (No in step S15 in FIG. 4), the ultrasonic diagnostic apparatus 10 ends the examination (step S16 in FIG. 4).

  Thus, for each analysis of the RAW data, the analysis time and the comment can be added, and the analysis history data can be updated by adding the number of analyzes n.

  According to the first embodiment of the present invention described above, thumbnails and analysis history data such as the generation time and the number of analyzes n are added to the collected RAW data and stored in the data storage unit 6 to analyze the RAW data. Sometimes, by displaying the analysis history list 71 on the display unit 7, RAW data necessary for analysis can be easily retrieved from analysis history data such as generation time and unanalyzed data.

  In addition, each time RAW data is analyzed, the analysis time and comments are added to the analysis data, and the analysis history data is updated by adding the number of analyses. RAW data necessary for analysis can be easily retrieved from time, comments, and the like.

  Further, the analysis history data is displayed together with the thumbnail of the RAW data. Further, the thumbnail of the RAW data is added to select a thumbnail useful for the search, and the thumbnail and the analysis history data are displayed to display the RAW necessary for the analysis. Data can be easily retrieved.
