Abstract

The Honeywell Medical Scanner has been developed to accurately measure human body temperatures in a laboratory environment. Specifically, it detects abnormal blood profusion, an indicator of cancer, in the breast and surrounding areas of the body. The scanner uses Honeywell's high performance TV compatible FLIR technology, similar to the AN/AAQ-9 and Chaparral FLIRs, to produce radiometrically calibrated FLIR imagery which may be digitized, for computer processing, or stored on video tape for playback at a later date. The calibrated imagery is produced by referencing the image seen by the front objective to two internal standards. These standards set the gain and level of the output video such that voltage out corresponds to a given observed temperature. By sampling a section of the frame and integrating over several frames, thermal resolution of 0.1°C may be achieved.
