Method of manufacturing an ultrasonic probe and the ultrasonic probe and an ultrasonic imaging apparatus

摘要

In order to reduce the impedance of an ultrasonic transducer array, an ultrasonic probe is provided in which a plurality of holes 34 are disposed running in the thickness direction of a piezoelectric material plate 32 and electrodes 36 are provided on the internal walls of the holes so as to exploit the ultrasonic vibration of the wall of piezoelectric material between the adjacent holes according to the electromechanical coupling coefficient k31. An ultrasonic imaging apparatus employing such an ultrasonic probe is also provided.
