Ultrasound diagnosis apparatus

Abstract

To provide an ultrasound diagnosis apparatus capable of appropriately assigning a transmission delay time of a group to a transducer without complicated wires. The ultrasound diagnosis apparatus of the embodiment comprises a plurality of transducers, a timing pulse generator, a switch part, and a switch controller. Ultrasound waves are transmitted to the transducers. The timing pulse generator has output terminals for outputting timing pulses based on a delay time to a channel corresponding to each of the transducers, in which a plurality of output terminals are divided into groups and each group has the output terminals of a specific number greater than two. The timing pulse generator then generates the transmission delay time within a predetermined time range for the each group. The switch part selectively connects the channels with the output terminals. The switch controller divides the plurality of channels into channel regions of the same number as the specific number, and controls the switch part so as to correspond between the groups and the regions by connecting the channels and the output terminals.
