ABSTRACT:
Apparatus for supplying signals to a vidicon which furnishes a color image of a selected portion of the human body, especially of the mamma, has an optical scanning system which transmits a thermal image of the selected portion of the body to a pyroelectric infrared detector without touching the selected portion. The detector transmits signals denoting the temperature of different spots of the selected portion of the body to a storage whose output transmits signals to the vidicon, always via one of a series of threshold circuits which are calibrated to transmit signals to associated color matrices only when the intensity of such signals is within a range denoting the particular color. The matrices transmit signals to the vidicon so that the latter furnishes a color image of the selected portion of the body.
