Claim:
1. An X or Gamma ray detector, comprising: a conversion layer configured to convert X or Gamma rays to visible light; an imaging sensor comprising one or more CMOS or CCD die, each said die having an imaging area configured to detect visible light and a non-imaging area; a fiber optic plate (FOP) positioned between the conversion layer and the imaging sensor, said FOP having top and bottom surfaces separated by a plurality of sides, said FOP configured to transfer visible light onto individual pixels of the die and to block the X or Gamma rays from reaching the die, said FOP comprising a plurality of stand-offs attached to the plurality of sides about the periphery of the FOP and extending below the bottom surface of the FOP, said stand-offs contacting the non-imaging area of said one or more die to form a gap between the FOP and the imaging sensor; and a coupling material that fills the gap between the FOP and the imaging sensor.
