  • Feedback control system for ultrasound probe
    Patent number: 6577042
    Abstract: A control system for a probe, including a transmission member, comprises a power source for supplying a constant power to a transmission member and a transducer for coupling the constant power to the transmission member and for providing a mechanical output to the transmission member at a frequency. A frequency measuring device is also provided for constantly measuring the frequency of the mechanical output of the transducer. A current monitoring device for measuring current forwarded to the transducer which monitors the current while the frequency of said mechanical output is varied until it is determined at what frequency the current is at a maximum is also provided. A method for implementing this apparatus is also provided.
