摘要:
There are provided a transducer that irradiates an ultrasonic wave, a transmitter that drives the transducer, and a plurality of power sources that supply a plurality of positive voltages and negative voltages to the transmitter. The transmitter includes a plurality of switches (SW1 to SW4) that connect the power sources selectively, and a timing controller that controls a plurality of the switches. A driving pulse is generated through a selection of the switches. A plurality of the positive voltages and a plurality of the negative voltages have absolute values different from each other. With this configuration, it is possible to provide an ultrasonic diagnostic apparatus that allows the amplitude of the driving pulse to be varied in multiple stages, is low in cost, and requires small amounts of both material and control.
