<p>PROBLEM TO BE SOLVED: To provide a Doppler calculation method which has a small calculation amount and can perform high-speed calculation.SOLUTION: An ultrasonic diagnostic device generates compression data consisting of a representative amplitude value and representative time for each half-waveform by calculating a representative amplitude value and representative time of a half-waveform sandwiched by two mutually-adjacent zero cross points of a reception signal for each half-waveform, and calculates the movement of an analyte component in an analyte on the basis of a deviation amount of a region in which waveforms are approximate with each other at the time when the representative amplitude values constituting the generated compression data are arranged in the corresponding representative time.</p> |
