An ultrasonic diagnostic apparatus comprises an ultrasonic probe configured to transmit ultrasound to a test body and receive an echo signal, an image generation unit configured to generate a plurality of tomograms with respect to the test body based on the echo signal, an image memory configured to record the generated tomograms, and a control processor. The control processor performs control such that image processing of extracting a microstructure is performed, using correlation between a tomogram stored in the image memory and a tomogram corresponding to a position of the ultrasonic probe at that point in time. The microstructure-extracted image is displayed on the display part in a predetermined form.
