ABSTRACT:
Disclosed is an ultrasonic diagnostic apparatus that can dynamically change a focus position of a phasing circuit installed in a sub-array. A transducer element is two-dimensionally arrayed and constitutes a sub-array. The sub-array is two-dimensionally arrayed and constitutes an arrayed transducer element. An output of the transducer element of the sub-array is sent to a phasing circuit and a phasing circuit. Outputs of the phasing circuits are coupled by a coupling circuit. All of the foregoing transducer elements, sub-arrays, phasing circuits and coupling circuits are accommodated in a probe handle. An output from the coupling circuit is sent through a probe cable to a delay adding circuit of a main body. Also, the phasing circuits are controlled by a control circuit. An output of the delay adding circuit is processed by a signal processor and displayed on a display.
