Raster scanning system for scanning 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.
