Abstract
In order to properly discern a plurality of streams of blood flow having different contrast agent arrival times or blood concentration properties, an ultrasonic diagnostic apparatus comprises: an ultrasonic probe a transceiver section a quadrature detector section a power calculating section for calculating the power P of blood flow; a power peak holding section for comparing the latest power P and a predecessor peak value Po, and outputting the larger one as a peak value P′ and an elapsed time t′ corresponding to the peak value P′; a predecessor power/elapsed time keeping section for keeping the predecessor peak value Po and the corresponding elapsed time 'to' and outputting these values to the power peak holding section a timer for measuring an elapsed time t from a reference time; a blood flow image producing section for producing a power peak hold blood flow image G in which the hue is changed before and after the elapsed time t′ reaches a hue change time tc and the brightness varies depending upon the peak value P′; an operating section for resetting the timer and specifying the hue change time tc; and a display For example, blood flow passing through the hepatic artery and that passing through the portal vein can be displayed in different colors.
