Abstract:
An image receptor for an X-ray apparatus having light directing properties including:a) a lead glass panel having a first surface and a second surface, said first surface being coated with polarizing filter layer, said polarizing filter layer being coated with a phosphor layer, said phosphor layer being coated with a white pigment layer, said white pigment layer being coated with a black pigment layer, said second surface having at least one camera assembly directly coupled thereto; and wherein X-rays from an X-ray source travel first through the black pigment layer, then subsequently the X-rays pass through the white pigment layer to and towards the phosphor layer where the X-rays are converted to visible light rays, the visible light rays subsequently pass through the polarizing layer, then subsequently through the lead glass panel to and towards the camera assembly, said white pigment layer increasing a brightness of the visible light rays passing through the lead glass panel by reflecting a majority of the visible light rays towards the camera assembly.
