ULTRASONIC DIAGNOSTIC DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce influence of spike noise generated in an element selection switch. ! SOLUTION: An ultrasonic diagnostic device 100 includes: an ultrasonic probe 2 which has a plurality of vibration elements respectively provided with a first terminal and a second terminal; a vibration element selection part 33 which selects a vibration element required for ultrasonic transmission and reception by interlockingly turning ON/OFF a first element selection switch connected to the first terminal and a second element selection switch connected to the second terminal of each of the plurality of vibration elements; a transmission part 31 which supplies a prescribed drive signal to the selected vibration element to radiate a transmission ultrasonic wave to a subject; a reception part 32 which phases and adds reception signals of a plurality of channels obtained from the vibration element on the basis of a reception ultrasonic wave obtained from the subject with radiation of the transmission ultrason
