Ultrasonic diagnostic apparatus and control program thereof

摘要

A transmission/reception unit (21) executes first ultrasonic transmission using a sound pressure that does not substantially destroy the contrast medium bubbles and is required to obtain an ultrasonic image of the subject and a second ultrasonic transmission using a sound pressure that is required to destroy the contrast medium bubbles and higher than the sound pressure in the first ultrasonic transmission based on a transmission parameter specified by a control processor (25) in accordance with each frame or each volume. The control processor (25) changes the transmission parameter concerning the second ultrasonic transmission in accordance with time with respect to the transmission/reception unit (21).
