Abstract
Microwave apparatus for diagnosis of cancer of the breast includes a microwave transmitter and a microwave antenna for directing a microwave signal to the breast under examination, and a microwave receiver having amplitude and phase shift detectors for receiving of reflected microwave signals. A processor is connected to the receiver for processing the amplitude and phase information to detect and locate cancer in the breast. A matching plate having a dielectric constant substantially the same as normal breast tissue is located between and in engagement with the breast and antenna. The antenna engages and sweeps over the plane surface of the matching plate to eliminate any air gap in the transmission path. A display unit is connected to the processor to create a microwave image of cancer growth, if any.
