  • Patent number: 6052432
    Abstract: An x-ray image intensifier includes a photoconductive x-ray detector having an electro-optic light modulator disposed on a photoconductive detector layer. The photoconductive x-ray detector absorbs x-rays passing through an object to be imaged to form an x-ray exposure of the object. An optical image of the x-ray exposure is generated when light passes through the photoconductive x-ray detector. An imager captures optical images of the x-ray exposures. A processor coupled to the imager digitizes and stores the optical images of the x-ray exposure captured by the imager at selected intervals.
    Type: Grant
    Filed: December 7, 1998
    Date of Patent: April 18, 2000
    Assignee: Sunnybrook Hospital
