ULTRASONIC DIAGNOSTIC DEVICE

WIPO Patent Application WO/2011/036891

A1

Disclosed is an ultrasonic diagnostic device provided with: a transmitting/receiving unit which repeatedly drives a probe, receives through the probe reflected echoes obtained as the ultrasound wave transmitted by means of driving the probe reflects off a subject, and sequentially generates a plurality of receiving signals; a color flow mapping signal processing unit which sequentially generates blood flow rate data of the blood flow portion of the subject's body for each frame on the basis of the plurality of received signals; a remaining image processing unit which processes the remaining images for each frame with respect to the blood flow rate data; a tomographic image signal processing unit which generates a B-mode tomographic image frame data on the basis of the receiving signals; and an image synthesizing unit which synthesizes the blood flow rate data that was processed by the remaining image processing unit and the B-mode tomographic image frame data. The remaining image processing unit performs a folding assessment on the basis of the blood flow rate data of the newest frame and the blood flow rate data that was processed by the remaining image processing unit of the frames before the newest frame and dynamically changes the coefficient of persistence on the basis of the results of the folding assessment and the blood flow rate data of the newest frame and the frames therebefore.
