An ultrasonic diagnostic apparatus (1) comprises an ultrasonic probe (12) configured to transmit ultrasound to a test body (P) and receive an echo signal, an image generation unit (25) configured to generate a plurality of tomograms with respect to the test body (P) based on the echo signal, an image memory (26) configured to record the generated tomograms, and a control processor (28). The control processor (28) performs control such that image processing of extracting a microstructure is performed, using correlation between a tomogram stored in the image memory (26) and a tomogram corresponding to a position of the ultrasonic probe (12) at that point in time. The microstructure-extracted image is displayed on the display part (14) in a predetermined form.
