The resolution, contrast, and clinical appearance of radiographs and duplicate radiographs made with two types of duplicating film were compared. Duplicating conditions evaluated were type and shape of light, light-film distance, type of exposure surface, and developer temperature. Major observations were as follows: both Kodak and DuPont films produced clinically acceptable duplicates; Kodak film was faster; DuPont film responded better in incandescent photoflood light than Kodak film; clear glass with appropriate light-film distance was the best exposure surface.
比较了使用两种类型的复制胶片制作的X光片及复制X光片的分辨率、对比度和临床外观。评估的复制条件包括光源类型和形状、光源与胶片的距离、曝光面类型以及显影液温度。主要观察结果如下:柯达胶片和杜邦胶片都能制作出临床可接受的复制品;柯达胶片速度更快;在白炽灯泛光下,杜邦胶片比柯达胶片反应更好;具有适当光源与胶片距离的透明玻璃是最佳曝光面。
