PROBLEM TO BE SOLVED: To reduce the quantity of mensuration and the diagnostic time by mensurating the index value for Doppler diagnosis every heartbeat range recognized by a heartbeat recognizing means. SOLUTION: A freeze memory 205 is reproduced after freezing, and a Doppler spectrum to be diagnosed is displayed on an indicator 104. When a mensuration start is instructed on an operation panel 207 in this displayed state, an automatic arithmetic processing is performed, and the frequency trace by a trace arithmetic part 201 and identification of parameter point such as PSV, EDV or the like by an index arithmetic part 202 are performed. Further, the heartbeat identification by a heartbeat identification arithmetic part 203 and the index operation by an index arithmetic part 204 are performed, and each arithmetic result is displayed on the indicator 104. The index is also displayed in the Doppler image of the indicator 104. According to this, the time and operation quantity required for the mensuration can be reduced. |
