Abstract
Abstract A cellularized radiation sensitive structure is provided in which a laser is utilized to cut narrow slots in a sheet of luminescent material. These slots, usually cut in an X-Y pattern, are then filled with a material which is opaque to either light or radiation or both. This forms a structure having a plurality of individual volumes of luminescent material separated by opaque material. Each of the individual volumes of luminescent material may have associated therewith a photodiode element to produce an electrical signal which is a measure of the light output from that volume.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
121 words
A structure for responding to X-ray radiation, comprising a cellularized member of luminescent material which emits light in response to X-ray radiation, said member comprising a plurality of volumes of said luminescent material separated by wall members, a photoconductive layer disposed on one surface of said cellularized member to be exposed to X-rays, an electroluminescent layer disposed on the opposite side of said cellularized member from said photoconductive layer, and a source of electrical energy connected to said photoconductor and said electroluminescent material, said luminescent material emitting light in response to X-ray radiation to vary the photoconductive effect exhibited by said photoconductive layer, said variations in photoconductive effect producing variations in the potential across and the electroluminescence of said electroluminescent layer.
Claim 2
Dependent Claim
121 words
A structure for responding to X-ray radiation, comprising a cellularized member of luminescent material which emits light in response to X-ray radiation, said member comprising a plurality of volumes of said luminescent material separated by wall members, a photoconductive layer disposed on one surface of said cellularized member to be exposed to X-rays, an electroluminescent layer disposed on the opposite side of said cellularized member from said photoconductive layer, and a source of electrical energy connected to said photoconductor and said electroluminescent material, said luminescent material emitting light in response to X-ray radiation to vary the photoconductive effect exhibited by said photoconductive layer, said variations in photoconductive effect producing variations in the potential across and the electroluminescence of said electroluminescent layer.
Claim 3
Dependent Claim
42 words
Apparatus in accordance with claim 1 in which said volumes of luminescent material are formed by pairs of wall members having a serpentine member disposed therebetween, the luminescent material being disposed in the spaces between said wall members and said serpentine member.
