Abstract
An ultrasonic transducer probe is provided, in which the transducer is oscillated by a crank shaft for sector scanning. The crank shaft is driven by a motor having a moving magnet stack assembly in a tubular set of electromagnetic coils. The motor also moves a bimetallic pin through a position sensor coil so that the position of the transducer is represented by the detected inductance change of the coil.
