Abstract

Obtaining hard copy images from some diagnostic medical procedures, such as Computed Tomography and Ultrasound, involves photography of video images. This is often done with cameras utilizing a negative type transparency film. Selecting a film for this application should include considerations of the characteristics of the cathode ray tube (CRT) being photographed and the properties of a video image. This paper describes CRT characteristics and their effects on film selection. The major film parameters which should be considered in selecting a film for video imaging are discussed. Our results indicate that optimum imaging is achieved with a relatively high speed, high contrast orthochromatic film.
