Abstract

KODAK RETNAR minification products have been developed to minify radiographs onto a film chip carried by an aperture card with mini-mum loss of diagnostic quality. Converting radiographs to aperture cards reduces storage requirements and adds the convenience of a miniature unit record. The products center around a new film developed for minifying radiographs. The film combines extended exposure scale and near unity contrast with a direct positive photographic response. A bright, efficient reader displays the film's broad density range. A camera-processor exposes a radiograph at a 12.5 reduction on the camera card film, processes and dries the film while mounted in the card, and prints eye-readable information on the card. This unit can be operated by clerical personnel in a typical file room or office environment.
