Device for detecting, measuring, and recording body thermal emissivity

摘要

A device is disclosed for detecting thermal differentials emanating from a radiant source by transforming such differentials to visible representations that can be photographically recorded for subsequent diagnostical and analytical study. The device is especially useful in the early detection of cancer or of other contralateral heat differentials in the body due to various abnormal or disease conditions or to monitor chemotherapy or progress of surgical recovery.
