Abstract

Abstract An image displaying method in an ultrasonic diagnostic apparatus obtains differential image data between first image data and second image data in image data sequentially obtained from an echo signal received by transmitting an ultrasonic wave to a body to be examined. A time difference between a point of time, where the first image data are measured, and another point of time, where the second image data are measured is determined. A synthesized image data capable of displaying simultaneously a differential image and the time difference by combining the differential image data and data representing the time difference is obtained and displayed.
