2.1.1 Principle

Tissue changes associated with cancer cause significant changes in
local dielectric properties of tissue. These dramatic shifts in electrical
impedance result from cytological and histological changes involving
cellular water content, amount of extra-cellular fluid, membrane
properties and packing density and orientation of cells that are typical
of malignant tissue transformation.
The electrical impedance (both conductance and capacitance) of
malignant tissue is typically 20-40 times lower than that of normal
tissue when measured at appropriate frequencies.
TransSpectral Impedance Scanning (TS2000) detects cancerous
changes in the breast by providing a real-time, two-dimensional visual
display of local variations in tissue electrical conductance and
capacitance. Changes in tissue electrical conductance and capacitance
associated with malignancy result in a characteristic signature that can
be readily identified in the TS2000 image.
TS2000's unique potential to distinguish and detect early signs of
cancer is based upon detecting these electrical changes non-invasively.
TS2000 (Trans-Spectral Impedance Scanning) is a unique system
designed specifically for non-invasive, accurate detection of early
stage breast cancer.
