Abstract

New computed radiography utilizing the phenomena of photostimulated luminescence (PSL) was developed to resolve the essential problems of the conventional radiography utilizing the intensifying screen-film combination. The basic constituents of the system are "Imaging Plate", in which photostimulable phosphors are used as the memory material for temporarily storing X-ray image; "Image Reader", which converts the latent image on the plate into digital time-series signals; "Image processor", which manipulates the image digitally with a high speed computer; "Image Recorder", which records the processed signals on a photographic film. The plate can be used repeatedly to store X-ray image simply by flooding it with light to erase the residual energy.
