<P>PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus allowing proper allocation of a transmission delay time of a group to a vibrator without complicating wiring. <P>SOLUTION: This ultrasonic diagnostic device includes a plurality of vibrators, a timing pulse generation means, a switch means, and a switch control means. Ultrasonic waves are transmitted from the vibrators. The timing pulse generation means has output terminals for outputting timing pulses based on a delay time to channels corresponding to each vibrator, the plurality of output terminals are divided into output terminal groups each having a prescribed number not less than two of output terminals, and the timing pulse generation means generates the transmission delay time within a prescribed time range in each group. The switch means selectively connects the channels and the output terminals. The switch control means divides the plurality of channels into the regions of the channels of the same number as a prescribed number, and connects the channels and the output terminals to control the switch means so as to associate the groups and the regions. <P>COPYRIGHT: (C)2013,JPO&INPIT |
