Dielectric imaging for localisation and detection of breast tumours

A new type of resonant dielectric sensor has been developed which is noninvasive but has adequate depth sensitivity for the detection of tumors. In the measurement in ' and in " are estimated from the changes in resonant frequency and Q factor, respectively. A clinical measurement system has been tested on a breast tumor equivalent phantom and on patients and controls, and has been shown to be capable of demonstrating the presence of a tumor.<
