ABSTRACT:
The interior of a subject to be examined is scanned with an ultrasonic wave through an ultrasonic probe. Original image data is created based on a signal obtained. The original image data is image-processed. The image-processed image data is displayed. In the image processing, the original image data is compared at each pixel with a predetermined threshold value. If being higher than a threshold value, the original data is selected at each pixel. If, on the other hand, the original image data is lower than the threshold value, image data image-processed previous to one frame or a few frames is selected at each pixel. The image data selected for each pixel is displayed as newly image-processed image data. If the original image data is thus lower than the threshold value, the image data image-processed previous to one frame or a few frames is selected and, when an object is in given motion, a residual image is displayed on a motion locus.
