1. A high resolution radiation detecting apparatus for generating electrical signals representative of the intensity of incident primary radiation, the apparatus comprising:

  • at least one scintillation crystal for receiving primary radiation and generating corresponding secondary radiation, said at least one scintillation crystal including a front face for receiving incident primary radiation, a back face opposite said front face and top and bottom emission faces for emitting at least a portion of said secondary radiation, the distance between said front and back faces being sufficiently great to allow a desired portion of said primary radiation to be stopped by said at least one scintillation crystal, and the distance between said top and bottom emission faces being sufficiently small to minimize the scattering of said secondary radiation within said scintillation crystal before the secondary radiation is emitted from the crystal;

    detector means including a plurality of radiation detecting elements, each element having means for generating an electrical signal representative of the intensity of incident secondary radiation; and

    coupling means for passing the secondary radiation emitted from areas of at least one of said emission faces to associated detecting elements.
