Abstract
A luminescent storage screen having a stimulable phosphor for the latent storage of x-ray images, of the type wherein the latent image is read-out by excitation of the stimulable phosphor with a read-out beam having a first wavelength, causing radiation of a second wavelength to be emitted, which is acquired by a detector, the storage screen having lateral faces of disposed at an angle with respect to one of the end faces of the storage screen which is less than 90.degree.. The end faces are transparent so that radiation of the second wavelength can exit the screen from the end faces.
Claims8
In a system for storing and reading-out x-ray images having a luminescent storage screen containing a stimulable phosphor in which an x-ray image is latently stored, said stimulable phosphor emitting radiation at a second wavelength when excited by radiation of a first wavelength, the improvement comprising said luminescent storage screen having end faces, said stimulation radiation entering said luminescent storage screen through one of said end faces, and lateral faces joining said end faces, with the entirety of said lateral faces being disposed at an angle relative to said one of said end faces which is less than 90.degree., said end faces being transparent to said radiation of said second wavelength for permitting said radiation of said second wavelength to exit said luminescent storage screen.
