ABSTRACT:
Apparatus is provided for illuminating medical diagnostic imaging film with significantly enhanced contrast and resolution. The apparatus includes an enclosure having a first end and a second end in opposing relationship therewith, and a concave mirror or the like located in the enclosure proximate to the first end and receiving light from a light source such as a light pipe. The mirror projects at least a portion of the received light, in the form of a collimated beam, toward the second end of the enclosure. The apparatus further includes a light transmissive panel positioned across the second end of the enclosure to support the film in the path of the collimated beam, for illumination thereby. In one embodiment, the film support panel is selectively curved to minimize reduction in field of view.
