  A configuration diagram of the measurement information of the living tissue received from the probe 11 is shown in FIG.

  The measurement information of the living tissue is handled in units of frames, and one frame is composed of a plurality of acoustic scanning lines.

  Furthermore, the acoustic scanning line is composed of image data and additional information such as a header and a footer.

  This additional information includes data unique to each acoustic scanning line and data common within the frame.

  The data unique to each acoustic scanning line is, for example, information indicating the acoustic scanning line number in the frame, the start position and the end position of the acoustic scanning line, and different values are held for each acoustic scanning line in the same frame. ing.

  The intra-frame common data is, for example, a diagnostic device such as the probe type, frequency, depth, and diagnostic mode, and data and frame number indicating the diagnostic status, and is equal for each acoustic scanning line in the same frame. Holds the value.

3 and 4 are sub-block diagrams of the data compression / deletion unit of the ultrasonic diagnostic apparatus according to the second embodiment of the present invention.

  3 and 4, the same reference numerals as those in FIG. 1 denote the same components as those shown in FIG.

  Therefore, the detailed description of these components will be omitted, and only different points will be described.

  Here, there is no additional information to be compared only when data enters the similarity detection unit 32 for the first time, for example, immediately after starting the system.

  Therefore, the first data is not compared by the similarity detection unit 32 and stored in the internal memory as comparison data.

  When the second and subsequent data enters the similarity detection unit 32, it is compared with the comparison reference data to determine whether the data is to be compressed / deleted.

  Here, if it is determined that the comparison results are different, the comparison control data stored in the similarity detection unit 32 is updated.
