1. An ultrasonic diagnostic apparatus comprising:
- (1) ultrasonic transmitting-receiving means for transmitting and receiving an ultrasonic wave to and from a body to be inspected;
(2) tomographic scanning means for obtaining tomographic image data of a predetermined portion of said body to be inspected from a reflected echo signal from said ultrasonic transmitting-receiving means in a time series;
(3) means for generating differential image data of images by performing a differential operation upon said images in said time series which have been obtained by said tomographic scanning means;
(4) means for providing color codes which designate display colors to said differential image data;
(5) means for cumulating a plurality of frames of said differential image data; and
(6) means for displaying said cumulated plurality of frames of said differential image data in colors designated by said color codes.

Abstract
The present invention includes an ultrasonic diagnostic apparatus for forming differential image data by performing differential operation among topographic image data obtained in time series, an apparatus for giving color codes which designate display colors to differential image data, an apparatus for cumulating a plurality of frames of differential image data, and an apparatus for displaying respective cumulated differential images in colors designated by the color codes in which motion of a moving portion of a patient'"'"'s body is displayed in colors by superposing a plurality of differential images.
