The anticipated benefits of digitized projection radiographic data to medical imaging has generated much interest and activity. Numerous methods for capturing the radiographic image data prior to digitization are being evaluated. In this paper the excellent performance of the film-screen system as a receptor for projection radiographic data is discussed. An experimental system for obtaining high quality digital radiographic data by laser scanning radiographic films is described. This system is being used to evaluate the clinical utility of various digital image processing algorithms. Future plans include an investigation of quantitative analysis of projection radiographic data. Digital data obtained by film scanning can be used with digital image archiving and communications systems.
数字化投影射线照相数据给医学成像带来的预期益处引发了广泛的兴趣和活动。目前正在评估多种在数字化之前捕获射线照相图像数据的方法。本文讨论了胶片 - 屏系统作为投影射线照相数据受体的卓越性能。描述了一种通过激光扫描射线照相胶片获取高质量数字射线照相数据的实验系统。该系统正用于评估各种数字图像处理算法的临床效用。未来计划包括对投影射线照相数据的定量分析进行研究。通过胶片扫描获得的数字数据可与数字图像存档和通信系统一起使用。
