Film radiography offers little opportunity to vary the technique, other than picking a different film type. CR also offers different imaging plates, but also there are many scanner control parameters that can be adjusted to the required inspection task, optimizing image quality and maximizing productiv...
(15分)CR(Computed Radiography)计算机放射摄影。它以成像板IP(Imaging plate)为 影像载体来替代传统的 X线胶片,采用与常规 X线摄影一致的投照技术,在 X线对成像板 曝光的同时记录下 X线影像信息,接过信息的读取与处理后,即可获得数字化的信号。CR的构成主要包括两大部分:成像板与信息读出装置。成像板是X线影像的...
