数字透视和X线摄影用硒基平板检测器已实验成功。这种平板式X线检测器可有效采集穿透人体的X线,直接转换成数字动态和静态影像,而且可获得高空间分辨力和高对比度的影像。这种新型X线检测器可以取代沿用了50多年之久的X线胶片和影像增强器。本文将讨论这种新研制的平板检测器的构造、特点和新一代X线诊断系统的优点。 Selenium plate detector for digital fluoroscopy and radiography has been experimentally successful. This flat-panel X-ray detector efficiently transgresses human-body X-rays and converts them directly into digital dynamic and still images with high spatial resolution and high contrast. This new X-ray detector can replace X-ray film and image intensifiers that have been in use for more than 50 years. This article will discuss the newly developed flat panel detector structure, characteristics and the advantages of a new generation of X-ray diagnostic system.
