Abstract
An ultrasound diagnostic apparatus according to a present embodiment includes driving pulse generating circuitries and a transmission control circuitry. The transmission control circuitry turns on a switching element of respective driving pulse generating circuitries of the driving pulse generating circuitries to be grounded, and thereby controls so as to make an output impedance of the respective driving pulse generating circuitries become a low impedance. The transmission control circuitry turns off the switching element of the respective driving pulse generating circuitries, and thereby controls so as to make the output impedance become a high impedance by means of a resistance value of the resistance. The transmission control circuitry controls so as to make the output impedance of the respective driving pulse generating circuitries become a lower impedance during a transmission period in which the ultrasound is transmitted than during a reception period in which a reflected wave of the ultrasound is received.
