Since the advent of xeroradiography, many questions have been asked about its image quality and speed relative to that of periapical and screen films. The experiment reported here measures the "resolution" of occlusal film, screen film, and xeroradiographs at different k Vp and mAs settings. The occlusal film was used instead of the periapical film because it has the same speed as a periapical film and is sufficiently large for the placement of the measuring instrument (a test pattern).
自从干板X线摄影术问世以来,人们就其图像质量以及与根尖片和增感屏胶片相比的成像速度提出了许多问题。本文报道的实验测量了在不同管电压(kVp)和管电流-时间积(mAs)设置下,咬合片、增感屏胶片和干板X线片的“分辨率”。使用咬合片而非根尖片,是因为它与根尖片速度相同,且面积足够大,可放置测量仪器(测试图案)。
