Paper Abstract

A new computed radiography system is described in which a charged selenium photoconductive plate is exposed to x-rays to create an electrostatic latent image, developed with a luminescent toner, and scanned with a stimulating laser beam to produce emitted light, which is filtered and detected. The resulting electronic signals are processed, and converted to hard copy using a laser film printer. The system is characterized by high x-ray sensitivity and by very high spatial resolution, which makes it particularly suitable for applications such as mammography and bone radiography. The image luminescence is bright and its decay time is extremely short, enabling rapid scanning with an inexpensive laser source. Also, the electronic capture of image data permits enhancement of the displayed contrast of image structures by image processing techniques.
