1. An improved apparatus for noncontacting measurement of subcutaneous body temperature distributions in a body, said improved apparatus comprising:

  • an elliptical reflector for receiving emitted electromagnetic thermal radiation from a subcutaneous point in said body and for focusing said received thermal radiation, said reflector having an aperture diameter of between 50 to 100 cm and an object focal length of between 0.6 and 1.6 times said aperture diameter,a receiving horn imbedded into the image focal point of said reflector for receiving said focused thermal radiation,means operatively connected to said receiving horn for generating an output indicative of the subcutaneous body temperature at said point, said reflector, horn, and generating means being capable of operating in the microwave thermal radiation range of 8 to 36 GHz, andmeans for supporting said elliptical reflector with said imbedded receiving horn above said body at a distance equal to the object focal length of said reflector less the depth of the subcutaneous tissue.
