Ultrasonic diagnostic apparatus, doppler measurement apparatus, and Doppler measurement method |
摘要 |
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. |

1. An ultrasonic diagnostic apparatus, comprising:
a Doppler processing circuit configured to generate a Doppler spectrum from an ultrasonic signal reflected from a predetermined region in a heart; a control processing circuit configured to generate temporal changes in a predetermined spectrum component in the Doppler spectrum as a plurality of trace waveforms, and generate a corrected trace waveform by interpolating a trace waveform of the plurality of trace waveforms that has a loss portion, using an estimation point input for the trace waveform, the estimation point specifying a blood flow velocity at a given time, wherein the control processing circuit is configured to generate the corrected trace waveform so that the corrected trace waveform passes through the estimation point; and a display configured to output a plurality of trace waveforms including the corrected trace waveform. |
