Abstract:
An ultrasound probe according to one embodiment includes a plurality of ultrasound vibrators, a switching part, and an amplification part. The ultrasound vibrator transmits ultrasound and receives ultrasound echoes reflected within a subject. The switching part is configured to cause aperture movement of ultrasound beams by selectively switching signals from two or more of the ultrasound vibrators. The amplification part is configured to amplify signals from the switching part. The ultrasound probe receives signals from the plurality of ultrasound vibrators in a time-division manner by controlling the switching part. In addition, the ultrasound probe further comprises an impedance transforming part. The impedance transforming part is configured to be interposed between the ultrasound vibrator and the switching part, receive signals from the ultrasound vibrator at high impedance, and output such to the switching part at low impedance.
