PROBLEM TO BE SOLVED: To provide ultrasonic diagnostic equipment capable of providing ultrasonic diagnostic images reflecting the speed and the amount of contrast media flowing each blood vessel in a diagnosis of a minute vascular bifurcation level. SOLUTION: This ultrasonic diagnostic equipment is provided with; an ultrasonic probe; a transceiver unit actuating the ultrasonic probe and transmitting/receiving ultrasonic waves relative to a subject; a control processor controlling the transceiver unit, executing transmission/receiving of low acoustic pressure pulses having an acoustic pressure substantially non-destroying contrast media bubbles and providing the blood flow circulating image on a predetermined region, and transmission/receiving of high acoustic pressure pulses having an acoustic pressure destroying the contrast media bubbles and eliminating the contrast media bubbles passing through a part of the predetermined region a plurality of times and, when executing the transmission/receiving of the low acoustic pressure pulses, transmits/receives the high acoustic pressure pulses; a button indicating the timing of transmitting/receiving the high acoustic pressure pulses; an image generation circuit generating ultrasonic tomographic image from the ultrasonic waves received by the transceiver unit; and a monitor displaying the ultrasonic tomographic image.
