ULTRASONIC DIAGNOSTIC APPARATUS AND CONTROL PROGRAM OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus in which signals obtained by signal estimation of a missing part have sufficient quality even when Doppler spectrum signals are non-stationary signals.SOLUTION: The ultrasonic diagnostic apparatus includes: an ultrasonic probe which performs ultrasonic transmission/reception for a Doppler mode and ultrasonic transmission/reception for other modes other than the Doppler mode; and a Doppler processing part 42 which performs orthogonal detection processing to echo signals obtained by the ultrasonic transmission/reception for the Doppler mode and then generates Doppler spectrum signals. The Doppler processing part 42 includes a signal estimation part 425 which estimates a missing part of the Doppler spectrum signals generated by the ultrasonic transmission/reception for the other modes by extrapolation processing.
