Abstract
A permanent color record of an image provided by a scanner employed in medical diagnostic procedures is formed on a standard sheet of 8.times.10 inch black-and-white film by three separate monochromatic record images of respectively different ones of three color components of the scanner developed image. The film sheet with its three black-and-white images is viewed on the screen of a viewer having three lenses positioned to project light of three different colors in converging paths through respective ones of the monochromatic record images and to project three image components in mutual superposition on the viewer screen. The three different color image components on the viewer screen are precisely positioned so that there is no visibly discernible misregistration. Either the three image components on the color record are formed on the sheet film with a predetermined maximum misregistration or the viewing system is adjusted to accomplish such maximum misregistration on the viewer screen.
