摘要：
The transmitting section of an ultrasound image diagnostic apparatus outputs a square pulse signal to allow a transducer to generate transmission ultrasound. The transmitting section sets the duty ratio of a pulse signal so that one of peaks of the first step response of the transducer which is generated when a change is made to voltage of the pulse signal overlaps with one of peaks of the second step response of the transducer which is generated when another change is made to the voltage of the pulse signal.
