title: Multi-image camera for spot radiography at fluoroscopic examinations.
abstract: The image quality of photofluorographic spot films (70, 100 or 105mm) has bee gradually improving as high resolution image intensification has evolved. With newly available 1023-line fluoroscopic monitors providing 2.8 line pairs/mm resolution, it is now possible to photograph diagnostic images directly off the monitor. Such images provide detail similar to that currently available on 100mm spot films. A multi-image camera has been modified to record spot films from the video disc image resulting in marked reduction in patient radiation and film cost. Initial findings incorporating pulsed fluoroscopy using a video disc are discussed.
