TLDR
It is shown that displaying planar two-dimensional maps of the currents detected at the breast's surface relate to the electric field distribution within the breast.Abstract:
In this paper we present the T-SCANTM technology and its use as a diagnostic tool for breast cancer detection. We show, using theoretical models with simplified geometries, that displaying planar two-dimensional maps of the currents detected at the breast's surface relate to the electric field distribution within the breast. This distribution is a manifestation of the bulk spatial inhomogeneities in the complex dielectric constant that represent the various tissue types. These differences may be used to discriminate between various pathological states. We furthermore illustrate a useful classifier, based on admittance data measured up to 2 kHz, and we argue that low frequency impedance measurements can be used successfully in breast cancer diagnosis.read more

Predictive Value of a Single Diagnostic Test in Unselected Populations
TL;DR: A new test for a disease is being evaluated it is customary to perform the test in two selected groups of subjects: those with an indisputable diagnosis of the disease by other criteria; and those from the normal population who have no evidence of the diseased and in whom all the factors known to result in a higher than normal risk can be excluded.

Dielectric properties of breast carcinoma and the surrounding tissues
TL;DR: The results seem to indicate that RF impedance imaging can potentially be used as a diagnostic modality for the detection of human breast carcinoma by suggesting structural and cellular inhomogeneities of the tumor tissue.

Skin impedance from 1 Hz to 1 MHz
TL;DR: The impedance of skin coated with gel but otherwise unprepared was measured at ten sites on the thorax, leg, and forehead of ten subjects, which suggests that the variation in skin impedance can cause errors in two-electrode electrical impedance tomographs.

Variability of impedivity in normal and pathological breast tissue
TL;DR: The collected data show that frequencies larger than 1 MHz are needed for the bio-electrical characterisation of breast tissue, and the reduced standard error of impedivity in breast tissue is about 0.1 or less.
