1. An improved method for noncontacting measurement of subcutaneous body temperature distributions, said method detecting the emitted thermal electromagnetic radiation in the microwave region from subcutaneous points having a diameter of substantially one-third wavelength focussed along predetermined scan lines, said improved method comprising the steps of:

  • detecting said radiation in the frequency range of 8 to 36 GHz,focussing said detected radiation with an elliptical receiving reflector having an aperture diameter of between 50 to 100 cm and having a focal length of 0.6 to 1.2 times the aperture diameter.
