Abstract:
1. An ultrasonic transmission/reception circuit comprising: a semiconductor circuit element including at least three terminals of a first terminal connected to a plurality of transducer elements that constitute an ultrasonic probe, a second terminal connected to a transmission signal generating circuit and a third terminal serving as an output terminal of an amplifier of a reception signal from the transducer element, and has a function of amplifying a signal inputted from one terminal by the other terminal and outputting the amplified signal between at least two terminals among the above-mentioned three terminals; and a control unit which performs control so as to cause the semiconductor circuit element to respectively perform a first function as a switch for inputting a transmission signal to the transducer element and a second function to amplify the reception signal from the transducer element.
