  • Radiation detector with microphotonic optical switches to route light in an imaging system
    Patent number: 6710350
    Abstract: An Radiation detector employs one or more arrays of microphotonic light transmission devices to selectively control the flow of light from different detection sites in a scintillator into an optical conduit. For example the microphotonic light transmission devices may be microelectromechanical steerable mirrors or light gates. Instead of employing a separate detector element to convert the light from each site into an electrical signal that is then switched into a data acquisition system, the present detector assembly switches the light into the optical conduit to the data acquisition system.
    Type: Grant

  • SCINTILLATOR ARRAYS FOR RADIATION DETECTORS AND METHODS FOR MAKING SAME
    Publication number: 20020131547
    Abstract: To provide simpler, more efficient methods for making scintillator arrays, one embodiment of the present invention is a method for making a scintillator array. The method includes extruding a mixture of a scintillator powder and a binder into rods; laminating the extruded rods with a sinterable reflector material; and sintering the laminated rods and reflector material into a scintillator block. Scintillator array embodiments of the present invention are useful in many types of pixelated radiation detectors, such as those used in computed tomography systems.
