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.

First claim

The invention claimed is:

1. An ultrasound diagnosis apparatus comprising:
a two-dimensional array of a plurality of transducers from which ultrasound waves are transmitted;
an ultrasound probe including the transducers with identification information for the transducers;
a timing pulse generator having output terminals for outputting timing pulses based on a transmission delay time to channels corresponding to respective of the transducers, in which the plurality of output terminals are divided into groups, with each group having the output terminals of a specific number greater than two, and the timing pulse generator being configured to generate the transmission delay time within a predetermined time range for the each group;
a switch part configured to selectively connect the channels with the output terminals, and
a switch controller configured to divide the plurality of channels into channel regions of the same number as the specific number of output terminals based on the identification information, cause the channels to be connected with the output terminals and control the switch part so that there is connection correspondence between the groups and the channel regions,
wherein the switch controller is configured to divide the plurality of channels corresponding to respective transducers into the channel regions, including channel regions in which the transducers are arranged in a two-dimensional array, so that, for each channel region, the respective transducers corresponding to each channel region have a transducer arrangement in which each transducer within the transducer arrangement is adjacent to another transducer within said transducer arrangement and is separated from each other transducer within said transducer arrangement by no more than a specific number of transducers within said transducer arrangement.

2. The ultrasound diagnosis apparatus according to claim 1 , wherein the switch controller is configured to divide the transducers at the timing when the ultrasound waves are transmitted and received.

3. The ultrasound diagnosis apparatus according to claim 1 , wherein the ultrasound probe is used correspondingly to a diagnosis mode, and the switch controller is configured to divide the transducers correspondingly to the diagnosis mode based on the identification information of the ultrasound probe.
