Ultrasonic ct device, control method of ultrasonic ct device, and ultrasonic transmission and reception device

A control method of an ultrasonic CT device, the ultrasonic CT device including:

• a transducer array in which a plurality of transducers are arranged;
• transceivers whose number is smaller than the number of the transducers;
• and
• a transmission transducer selector and a reception transducer selector disposed for each of the transceivers,
• the control method of the ultrasonic CT device comprising:
• connecting a transmitter included in the transceiver selectively to any of the transducers in the transducer array by the transmission transducer selector, and connecting a receiver included in the transceiver selectively to any of the transducers in the transducer array by the reception transducer selector simultaneously.

An ultrasonic transmission and reception device, comprising:

• transceivers whose number is smaller than the number of transducers included in a transducer array connected therewith;
• and
• a transducer selector disposed for each of the transceivers, wherein
• the transceivers each include a transmitter configured to transmit a transmission signal to the transducer, and a receiver configured to receive a reception signal received by the transducer,
• the transducer selector includes a transmission transducer selector and a reception transducer selector,
• the transmission transducer selector is configured to selectively connect the transmitter to any one of the transducers in the transducer array,
• the reception transducer selector is independent of the transmission transducer selector, and is configured to selectively connect the receiver to any one of the transducers in the transducer array, and
• the transmission transducer selector and the reception transducer selector respectively connect a transmitter and a receiver in one transceiver to the same or different transducers simultaneously.
