Ultrasonic probe and ultrasonic diagnostic apparatus
First Claim
1. An ultrasonic probe comprising:
- plural ultrasonic transducers for transmitting ultrasonic waves according to drive signals, and receiving ultrasonic echoes to output reception signals;
a signal processing unit for performing signal processing on the reception signals outputted from said plural ultrasonic transducers to generate a transfer signal;
an energy conversion unit for converting energy wirelessly fed from a power feeding device into electric energy;
a power receiving status detecting unit for detecting an amount of the energy wirelessly fed from said power feeding device, and determining whether or not said ultrasonic probe is within a region where the energy wirelessly fed from said power feeding device can be received; and
a transmitting unit for transmitting a determination result of said power receiving status detecting unit to said power feeding device.

Abstract
Power consumption is suppressed when received power is insufficient for wireless power feed to an ultrasonic probe. The ultrasonic probe includes: plural ultrasonic transducers for transmitting and receiving ultrasonic waves; a signal processing unit for performing signal processing on reception signals outputted from the plural ultrasonic transducers to generate a transfer signal; an energy conversion unit for converting energy wirelessly fed from a power feeding device into electric energy; a power receiving status detecting unit for detecting an amount of the energy wirelessly fed from the power feeding device, and determining whether or not the ultrasonic probe is within a region where the energy wirelessly fed from the power feeding device can be received; and a transmitting unit for transmitting a determination result of the power receiving status detecting unit to the power feeding device.
