Abstract:
1. An ultrasonic probe device comprising: a plurality of ultrasonic transducers, wherein each of the plurality of ultrasonic transducers is configured to transmit and/or receive ultrasonic waves in a frequency range that varies with a bias voltage value of a bias voltage applied to the each of the plurality of ultrasonic transducers; and a band control unit configured to perform a determination function to determine the bias voltage value of the bias voltage applied to the each of the plurality of ultrasonic transducers during an operation period of the plurality of ultrasonic transducers such that a predetermined continuous frequency band is covered by a combination of the frequency ranges of the transmitted and/or received ultrasonic waves from the plurality of ultrasonic transducers, wherein the determination function comprises determining:
