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.
随着高分辨率影像增强技术的发展，荧光摄影点片（70、100或105毫米）的图像质量已逐渐提高。有了新的1023线荧光透视监视器，其分辨率可达2.8线对/毫米，现在可以直接从监视器上拍摄诊断图像。这些图像提供的细节与目前100毫米点片的细节相似。已对多图像相机进行了改进，以从视频盘图像中记录点片，从而显著降低了患者的辐射剂量和胶片成本。本文讨论了结合使用视频盘进行脉冲荧光透视的初步结果。
