A method for enhancing the light output efficiency of a scintillation crystal, e.g. a NaI(Tl), scintillation crystal generally includes providing an input face of the scintillation crystal with a first set of substantially spaced apart, parallel channels that extend in a first direction along a portion of the input face of the crystal and providing a second set of substantially spaced apart, parallel channels in a portion of the input face of the crystal that extend in a second direction along a portion of the input face that is non-parallel to the first direction.
