A SCANNER FOR PHOTO-STIMULATABLE RADIOGRAPHIC MEDIA

摘要

A raster scanning system for scanning photo-stimulatable radiographic media (14) comprises a flying spot light source (10) adapted to fire a beam (11) at a rotating mirror (12) to form a stimulated area (13) of radiographic media generating emitted light (15). Collection optics (16) collect the emitted light and reflected light (17) from the radiographic media. A filter (18) permits the emitted light to pass to a charge coupled detector (CCD) (20). An analog to digital converter (22) receives the signal from the CCD. A control process unit (CPU) (24) receives the converted signal. An output device (26) processes the signal from the CPU.
