Abstract
An instrument for viscoelastic measurement, particularly for breast palpation, uses a sensing transducer head which contains at least two spaced, relatively small area transducers. The transducers can be fixed relative to a glove to be worn by an examiner or can be otherwise supported. The transducers have output leads connected to monitoring circuits which monitor differences in output of the transducers when both are pressed against breast tissue in order to sense thickened areas which may be too small to be sensed by manual palpation. The transducer may be attached to a position monitor so that the transducer head output can be continuously related to the location in space of the transducer head, and the output can be displayed in a suitable display.
