ABSTRACT:
An ultrasonic diagnosis apparatus comprises an ultrasonic wave transmitting/receiving unit for transmitting ultrasonic signals to a subject and receiving reflected echo signals reflected from the subject; a unit for controlling the ultrasonic wave transmitting/receiving unit such that the ultrasonic signals repetitively scan the subject at a predetermined scan period; an image memory unit for storing a plurality of image data pieces; a detection unit for detecting biophysical signals of the subject; a unit for setting a reference timing on the basis of the biophysical signals; an image display unit for displaying an image corresponding to the image data piece being delivered out of the image memory unit, the image display unit displaying the image at a predetermined display unit; a unit for controlling the image memory unit so as to store the plurality of image data pieces based on the reflected echo signals, wherein the plurality of image data pieces respectively correspond to two-dimensional images of the subject at different time points and the time points associated with the plurality of image data pieces are sequentially displaced by a first time interval and in synchronism with the reference timing; and a control unit for controlling the memory unit so as to sequentially deliver the plurality of image data pieces stored in the image memory unit at second time intervals longer than the first time interval during scanning of the ultrasonic signals.
