Abstract
A mm-wave imager has been developed for medical applications and will be reported here. It uses a single-channel mechanically scanned heterodyne radiometer and diffraction-limited focussing optics to achieve high resolution images of subcutaneous body temperature. The particular design constraints imposed by close-range operation (tens of centimetres) will be discussed. The instrument uses a novel, patented method for regular calibration of both the thermal and spatial response of the imager. Results obtained from healthy volunteers will also be presented.
