Abstract:
This article discusses using impedance measurements of body tissue in a diagnostic device. It then reviews the theory behind using these measurements to separate normal from diseased tissue. A small amount of time is devoted to discussing the meaning of sensitivity, specificity, and the receiver operating characteristic (ROC) curve, and their meanings. It also discusses the prospects of some new clinical devices using impedance measurements. One of the devices it focuses on is the TruScreen probe made by the Australian firm, Polartechnics.

Impedances and Admittance
Impedance is a measure of resistance to sinusoidal current flow in an AC circuit. Unlike their behavior in DC circuits, where inductors appear as short circuits and capacitors as open circuits, the behavior of these components in AC...
