Ultrasonic probe
First Claim
1. An ultrasonic probe comprising:
- an ultrasonic element unit for transmitting and receiving ultrasonic waves;
an oscillation mechanism for causing oscillation to the ultrasonic element unit; and
a detector for detecting oscillation of the ultrasonic element unit,wherein the detector detects an oscillation angle and an oscillation origin of the ultrasonic element unit, and in a state where an oscillation range of the ultrasonic element unit is divided at the oscillation origin into two regions of a positive region and a negative region, the detector outputs an origin-return signal that shows different logic levels depending on whether the ultrasonic element unit is located in the positive region or the negative region, anda control to return the ultrasonic element unit to the oscillation origin on the basis of the origin-return signal.

Abstract
The ultrasonic probe of the present invention includes an ultrasonic element unit for transmitting and receiving ultrasonic waves, an oscillation mechanism for causing oscillation to the ultrasonic element unit and a detector for detecting the oscillation of the ultrasonic element unit. The detector detects the oscillation angle and the oscillation origin of the ultrasonic element unit, and when the oscillation range of the ultrasonic element unit is divided at its oscillation origin into two regions of a positive region and a negative region, the detector detects in which area the ultrasonic element unit is located. In use of the ultrasonic probe, a control of origin return for returning the ultrasonic element unit to its oscillation origin is performed on the basis of the result of the detection by the detector.
