ABSTRACT:
An ultrasonic diagnostic apparatus includes a transmit/receive circuit having a plurality of transmit channels for enabling a drive pulse to a corresponding ultrasonic oscillation element and a plurality of receive channels for receiving an ultrasonic signal echoed back from a subject and an ultrasonic probe having a plurality of ultrasonic oscillation elements smaller in number than the number of channels in the transmit/receive circuit. The apparatus further includes a connector for selectively connecting a plurality of transmit channel output terminals in a parallel connection unit to a corresponding ultrasonic oscillation element to drive ultrasonic oscillation elements in parallel fashion or a plurality of receive channel input terminals in parallel connection unit to a corresponding ultrasonic oscillation element in the ultrasonic probe to receive an echo signal via the corresponding plurality of receive channels for processing.
