Instrument for assaying radiation
An instrument for assaying radiation includes a flat panel detector having a first side opposed to a second side. A collimated aperture covers at least a portion of the first side of the flat panel detector. At least one of a display screen or a radiation shield may cover at least a portion of the second side of the flat panel detector.
1. An instrument for assaying radiation, comprising:
a flat panel detector having a first side opposed to a second side, wherein the flat panel detector comprises a scintillation layer on the first side opposed to a photodiode layer on the second side;
a collimated aperture covering at least a portion of the first side of the flat panel detector;
a camera aligned with the first side of the flat panel detector.
2. The instrument as in claim 1 , wherein the collimated aperture comprises a pinhole collimator.
3. The instrument as in claim 1 , wherein the collimated aperture comprises a shadow collimator.
4. The instrument as in claim 1 , wherein the collimated aperture comprises a coded aperture collimator.
5. The instrument as in claim 1 , further comprising a radiation shield covering at least a portion of the second side of the flat panel detector.
6. The method as in claim 1 , further comprising a plurality of the flat panel detectors and an attenuator layer sandwiched between the plurality of the flat panel detectors.
7. The instrument as in claim 1 , further comprising a display screen covering at least a portion of the second side of the flat panel detector and a processor between the display screen and the flat panel detector.
8. An instrument for assaying radiation, comprising:
