Patent Number: 8,821,401

Title: Ultrasonic diagnostic apparatus, doppler measurement apparatus, and Doppler measurement method

Abstract: According to one embodiment, an ultrasonic diagnostic apparatus comprises a Doppler processing unit which generates a Doppler spectrum from an ultrasonic signal reflected from a predetermined region in a heart, a trace waveform generation unit which generates temporal changes in a predetermined spectrum component in the Doppler spectrum as a plurality of trace waveforms, a corrected trace waveform generation unit which generates a corrected trace waveform with the loss being interpolated by using a trace waveform, of the plurality of trace waveforms, which has a loss portion, and at least one estimation point input for the trace waveform, and an output unit which outputs a plurality of trace waveforms including the corrected trace waveform.
