    摘要： 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.

    摘要： An apparatus for detecting tumors in living human breast tissue includes instrumentalities for determining the dielectric constants of a plurality of localized regions of living human breast tissue. These instrumentalities include a bridge which is provided with a circuit for automatically nulling the bridge while in operation. Instrumentalities are provided for measuring variations in the dielectric constants over a plurality of the regions and for indicating the possible presence of a tumor as result of the measurement. The apparatus may be utilized in carrying out a method of detecting tumors which includes the steps of applying a plurality of probe elements to human breast tissue for sensing characteristics of localized regions thereof, applying an electrical signal to the probe elements for determining dielectric constants of localized regions of the tissue, sensing variations in the dielectric constants and determining the rate-of-change of dielectric constant at each of the localized regions.
