Abstract

PURPOSE:To eliminate the influence of noise at the time of switching, by inputting an output of a delaying means, and that which has inverted the output of the delaying means, to one of a pair of multiplexers, and the other, respectively, in the title device for executing a dynamic focus. CONSTITUTION:The titled device is provided with plural delaying means 5 for giving a delay for extracting an electric signal corresponding to a reflected pulse from each small area of a diagnostic object part of the inside of a body 80 to be inspected, to an electric signal outputted in accordance with reception of an ultrasonic pulse, from each of plural ultrasonic vibrators 7 in the ultrasonic diagnosis device for executing a dynamic focus. Also, a multiplexer 10 for selecting one of these delaying means 5 is constituted of a pair of multiplexers for selecting simultaneously the same output in accordance with the same control signal. In this state, the output of the delaying means 5, and that which has inverted the output of the delaying means 5 are impressed to one input terminal, and the other, respectively. Moreover, this device is provided with a differential amplifier 2 for impressing the outputs of this pair of multiplexers to an inversion input terminal and a non-inversion input terminal, respectively.
