摘要：

Electronically readable, large-area x-ray detectors that promise rapid access to the image for diagnosis, improved image quality relative to that of screen-film and storage phosphor-based radiography, reduced patient examination time, a reduction of consumable agents, and possibilities for reduced patient exposure will soon be commercially available for digital radiography.
