Abstract
These and other objects of the present invention are achieved by a process and apparatus for interrogating or scanning a photo-stimulable phosphor substrate containing projected image-wise information wherein a laser beam is directed towards a lens to produce a planar light beam directed onto the storage substrate as a focused light line to stimulate luminescent information detected by a linear sensor for collection and transmission to a computer assembly.

A process for scanning a photo-stimulable phosphor substrate having an image projected thereon with a light capable of producing readable photo-stimulable luminescent light from stored energy of the projected image-wise information which is detected, collected and stored in a computer assembly which consists of:
- directing a single laser beam to and through a lens to generate a planar light line to be focused as a light line on said photo-stimulable phosphor substrate to generate a scan line of said readable luminescent light;
- transporting said substrate through said planar light line to excite and interrogate said projected image-wise information;
- and
- collecting said generated luminescent light by a light detector CCD and storing said image in computer memory.
An apparatus for scanning a photo-stimulable phosphor substrate having an image projected thereon with a light source capable of stimulating photo-stimulable luminescent light from stored energy of the projected image-wise information which is detected, collected and stored on a computer assembly, which consists of:
- a single laser beam;
- a lens means on which said laser beam is directed for forming a planar light beam, said planar light beam directed to said photo-stimulable phosphor substrate to form a scan line thereon to generate luminescent light;
- a transport means for moving said photo-stimulable phosphor substrate in planar relationship through said apparatus and passed said scan line for interrogation;
- and
- collecting said generated luminescent light by a light detector CCD and storing said image in computer memory.
