<p><P>PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus suppressing crosstalk between channels. <P>SOLUTION: A plurality of vibrators 13 transmit/receive ultrasonic waves. A plurality of transmission circuits Tx generate drive signals for driving the plurality of vibrators 13. A plurality of reception circuits Rx perform signal processing of electrical signals from the plurality of vibrators 13. A transmission system has the plurality of channels Ch respectively corresponding to the plurality of vibrators 13. Each channel Ch connects the transmission circuit Tx, the vibrator 13, and the reception circuit Rx. A resistor part has a plurality of resistor modules Rm respectively branch-connected to the plurality of channels Ch. Each resistor module Rm can change over an electrical resistance value of each channel Ch between a resistance value HIGH and a resistance value LOW. A transmission control circuit 211 individually controls the plurality of resistor modules Rm so as to individually change over the electrical resistance values of the plurality of transmission lines Ch between the resistance value HIGH and the resistance value LOW. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
