Scintillation crystal with reduced light spreading

摘要

A scintillation camera crystal includes a plurality of light scattering holes in the crystal extending toward the photosensor and communicating with at least one surface of the crystal, the crystal is formed from a first material and the holes include a second material differing from the first material for deflecting the light generated by the scintillation crystal in response to incident gamma rays and reducing the spread of the generated light.
