Abstract
A thin layer of thermoluminescent material is formed on a substrate to form an image storage panel. A radiation image is projected onto the panel, and is stored by the thermoluminescent material. For reading, the panel is scanned by an infrared laser beam, and thermoluminescence proportional to the dose is emitted at the point of impingement of the laser beam. By scanning the storage panel with the laser beam, and by detecting the thermoluminescence, a series of emissions is obtained in the form of a video signal which is used to drive a display device.
