Patent ID: 8592775

Claim:
An apparatus, comprising: a scintillator body comprising a radiation absorptive material, a scintillating material, and a binder; the scintillator body further formed with a multiplicity of protruding parallel ribs on a first side), wherein the scintillator body forms a cylindrical portion, the apparatus further comprising a moderator positioned within the scintillator body; and a wavelength shifting fiber positioned between each adjacent pair of ribs, wherein each wavelength shifting fiber is in optical proximity to the adjacent pair of the ribs that the wavelength shifting fiber is positioned between; and further comprising the scintillator body formed with a second multiplicity of protruding parallel ribs formed on a second side, the apparatus further comprising a wavelength shifting fiber positioned between each adjacent pair of the second multiplicity of ribs, wherein each wavelength shifting fiber is in optical proximity to the adjacent pair of the second multiplicity of the ribs that the wavelength shifting fiber is positioned between.
