PCT No. PCT/JP97/00828 Sec. 371 Date Feb. 2, 1998 Sec. 102(e) Date Feb. 2, 1998 PCT Filed Mar. 14, 1997 PCT Pub. No. WO97/34530 PCT Pub. Date Sep. 25, 1997The present invention is directed to an ultrasound diagnostic apparatus which can display a superimposed picture of both B-mode and color flow mode images without loosing information of either image. The ultrasound diagnostic apparatus transmits an ultrasonic pulse signal to a specified region of a living body including its moving parts such as a blood flow and displays a status within that region of the living body based on reflected ultrasonic waves which have been received. The apparatus B-mode image display signal acquisition means for acquiring a B-mode image display signal derived from the scanned region, color flow mode image display signal acquisition means for acquiring a color flow mode image display signal which represents information on movements of blood and other moving parts in colors, translucent display processing means which performs a translucent display operation on the B-mode image display signal and the color flow mode image display signal, and display means which displays a synthesized image produced by superimposing a B-mode image and a color flow mode image based on a signal fed from the translucent display processing means.
