  • Patent number: 7164136
    Abstract: A detector for use in imaging applications includes at least one detector array, an array of photodetectors, and a continuous light guide disposed between the detectors and the photodetectors. The light guide is continuous over the entire area of the photodetectors and detectors. The thickness of the light guide is optimized based on the shape of the photodetector array. Each detector array includes a plurality of scintillator elements disposed in an M×N array, where “M” and “N” are independently selectable and are each at least one. A mechanism for maintaining the relative positions of the individual scintillator elements with respect to each other is provided. The retainer is further provided to enhance the separation between the individual detector arrays to define distinct boundaries between the position profiles of the scintillator arrays.

  • Publication number: 20040232343
    Abstract: A detector array including a plurality of scintillators for use in association with an imaging device. The detector array is provided for accurate determination of the location of the impingement of radiation upon an individual scintillator detector. An air gap is disposed between the scintillator elements, thereby increasing the packing fraction and overall sensitivity of the array. The amount of light transmitted down the scintillator element and the amount of light transmitted to adjacent elements is modified to optimize the identification of each element in a position profile map by adjusting the surface finish of the detector elements.

  • Publication number: 20040140431
    Abstract: A grid array adapted to receive a plurality of scintillators for use in association with an imaging device. The grid array is highly reflective such that location of the impingement of radiation upon an individual scintillator detector is accurately determinable. The grid array allows an air gap between each scintillator and the reflector material, as well as provides a highly reflective medium that produces sufficient light output while controlling cross-talk between the discrete scintillator elements. The grid array defines an M×N array of scintillator element cells. The grid array is manufactured using a conventional method such as injection molding. The grid array is fabricated from a highly reflective material. The scintillator elements are each cut to size and then inserted such that a uniform, flat surface to be achieved. In one embodiment, a bottom wall is be defined by each of the scintillator element cells.
