Abstract
Apparatus for detecting tumors in living human breast tissue comprising apparatus for determining the dielectric constants of localized regions of living human breast tissue including probe apparatus comprising a multiplicity of probe elements, apparatus for applying an AC signal to the tissue, apparatus for sensing electrical properties at each of the probe elements at a plurality of different times, and signal processing circuitry, coupled to the sensing apparatus for comparing the electrical properties sensed at the plurality of different times for providing an output indication of the dielectric constant of the localized region of breast tissue associated with the probe apparatus.
