Direct recording on rectilinear scan images on 4x5-in. film.
Rectilinear scans are usually recorded on 14 X 17-in. x-ray film. This is costly both in terms of film and storage space. Using 4 X 5-in. film instead of the larger film will reduce this cost. An Ohio-Nuclear Model 84FD dual-probe 5-in. scanner was converted for the production of scan images directly on 4 X 5-in film (Kodak SO-79 nuclear medicine film). The smaller images may be viewed directly on a standard x-ray viewbox, or they may be projected if a larger image is desired. The image quality is excellent. This system has replaced the 14 X 17-in. film at our institution.
