ULTRASONIC TRANSMITTER/RECEIVER, ULTRASONIC PROBE, AND ULTRASONIC DIAGNOSTIC APPARATUS

摘要

An ultrasonic transmitter/receiver which can reduce crosstalk between wires, an ultrasonic probe and an ultrasonic diagnostic apparatus. The ultrasonic transmitter/receiver comprises a transmission part (32) which transmits ultrasonic waves generated by a piezoelectric element when a transmission signal is inputted, a reception part (34) which is superposed directly or indirectly on the transmission part (32) and outputs a reception signal generated by the piezoelectric element when the ultrasonic waves are received, a pair of a transmission signal wire (38) and a transmission grounding wire for supplying the transmission signal to the transmission part (32), and a pair of a reception signal wire (37) and a reception grounding wire for taking the reception signal from the reception part (34). The transmission grounding wire and the reception grounding wire are used in common as a common grounding wire (39). The common grounding wire (39), the transmission signal wire (38) and the reception signal wire (37) are disposed on different sides of the transmission part (32) and the reception part (34) superposed with each other.
