<P>PROBLEM TO BE SOLVED: To form the maximum flow speed data excellent in continuity in a case that a stationary observation mode is selected. <P>SOLUTION: This ultrasonic diagnostic equipment 100 for forming the maximum flow speed data on the basis of a Doppler spectrum data obtained in a time series manner by the ultrasonic transmission and reception to a subject includes an input part 13 for selecting the stationary observation mode on the way of a real time observation mode, a threshold value storage part 6 for preserving a threshold value calculated on the basis of the noise level of the Doppler spectrum data obtained in a predetermined time phase determined on the bacis of observation mode starting timing, and an image data forming part 9 for forming the maximum flow speed data on the basis of the Doppler spectrum data obtained in the predetermined time phase determined on the basis of the threshold value read from the threshold value storage part 6 and a real time observation mode reopening timing. <P>COPYRIGHT: (C)2013,JPO&INPIT |
