Paper Abstract

Obtaining hard copy images from computerized medical imaging devices generally involves photographing video displays, often with a multi-image camera. Appropriate film selection for video photography with a negative type film requires considerations of the characteristics of the cathode ray tube (CRT) being photographed and the properties of a video image. Of particular importance is the contrast transfer characteristic of the CRT. In this paper we discuss the CRT characteristics and their effect on film selection. The significant film parameters are reviewed and their effects on film image quality are discussed. Our results indicate that a film for video photography should have high contrast (G = 2.5 to 3.0), relatively high speed, be orthochromatically sensitized and be single emulsion. Appropriate camera adjustment and quality control techniques are of major importance in achieving optimum film images, the former is briefly discussed.
