1. A probe for an ultrasonic imaging system for providing an output ultrasonic beam to scan human or animal tissue having a surface, said probe comprising:

  • a) rigid means for defining said surface in a manner rigidly supporting said human or animal tissue for imaging the same;

    b) transducer means for providing an output ultrasonic beam;

    c) motor means having an output shaft for providing oscillatory output motion;

    d) means for coupling said output shaft to said transducer means so that in response to oscillation of said shaft said output ultrasonic beam is directed in an arcuate path along said surface; and

    d) position feedback means mounted on said output shaft of said motor means between said motor means and said coupling means.
