ABSTRACT:
The microwave system is employed for the detection of cancerous tumors and is particularly effective in the early detection of such tumors. The system is of the dual type, combining in a single unit a passive radiometer with an active microwave transmitter. The sensitive passive microwave radiometer is adapted to sense subsurface temperatures, coupled with a solid state microwave transmitter for providing localized heating of the subsurface tissue, thereby taking advantage of the differential heating due to vascular insufficiency associated with the thermal characteristics of tumors, thus highlighting and enhancing early detection of cancer. The radiometer frequency is preferably higher than the microwave heating frequency with the microwave radiometer operating in C band and the transmitter in L band. An applicator forms the means by which the system couples to the radiating or emitting surface including a simple TE.sub.1-0 mode aperture defined by a single-ridged waveguide.
