Abstract
A fiber optic illuminating assembly for indirectly and uniformly illuminating the bore of a magnetic resonance (MR) scanner utilizes, in the preferred embodiment, a pair of plastic fiber optic bundles located in the bore behind a deflector element. The fiber optic bundles are made up of many optical fibers cut to different lengths to create point light sources spaced along the length of the bore. A frosted tube surrounds the bundle portion with the point light sources and operates to uniformly diffuse the light. The input ends of the fiber optic bundles are illuminated through an infrared mirror by a non-magnetic quartz-halogen light source operated from a direct current power supply to prolong filament life.
