Abstract
The ultrasonic probe according to any of embodiments includes a transmitting/receiving circuit, a power supply circuit, and a probe control circuit. The transmitting/receiving circuit is configured to control transmission and reception of ultrasonic waves. The power supply circuit is configured to function as a power source for the transmitting/receiving circuit. The probe control circuit is configured to determine a scan mode, and to control a frequency of switching noise of the power supply circuit according to the scan mode.
Claims8
An ultrasonic probe comprising:
- a transmitting/receiving circuit configured to control transmission and reception of ultrasonic waves;
- a power supply circuit configured to function as a power source for the transmitting/receiving circuit;
