ABSTRACT:
Apparatus for aiding in the identification of tissue type for an anomalous tissue in an impedance image comprising:
means for providing an polychromic immitance map of a portion of the body;
means for determining a plurality of polychromic measures from one or both of a portion of the body; and
a display which displays an indication based on said plurality of polychromic measures.
