PROBLEM TO BE SOLVED: To enable recording of echo data in a reprocessable signal form in ultrasonic diagnosis equipment. SOLUTION: Received digital signals output from an A/D converter 16 are divisionally taken out, processed by a predetermined way in a signal processing circuit 32, and stored in a recording medium 36 with a disk unit 34. The data contained in the recording medium 36 is processed in the signal processing circuit 32 by the disk unit 34 and sent to an image processing circuit 18. Although recording has been made in a video signal condition so far, recording of raw echo data facilitates reprocessing. The signal processing circuit 32 has a rate conversion function, a data addition and extraction function, a data protection function, and a data compression and elongation function, etc. |
