Abstract

A light box comprises two halogen 500 watt lamps supplied with DC rectified power, a scanning window made of 3 sheets, a thermoswitch, a fan and an intensity control circuit. The light box is adapted to be used with a reflective-type scanner. When a reflective-type scanner is mounted on the scanning window of the light box, the apparatus is able to scan substantially transparent materials, such as X-ray transparencies and to produce an image which can be used to determine the quality of the material of which physicians can use to perform radio-diagnosis.
