ABSTRACT:
An ultrasound therapy device has a hand-held transducer connected to a base unit having a front display and control panel. A control circuit within the base unit is microprocessor-based and enables an operator to select various output modes, intensities and durations. Transducer current, voltage, and phase angle are monitored for servo control, coupling detection, and fault protection of the output from an efficient power amplifier. Among the front panel displays is a percentage of coupling bar graph.
