Scintillator Array, a Scintillator, a Radiation Detection Apparatus Including the Scintillator Array or Scintillator, and Processes of Forming the Same

A scintillator array comprising:

• scintillator elements, wherein:
• each scintillator element includes a photosensor surface and a first side surface adjacent to the photosensor surface;
• the photosensor surface is adapted to provide scintillating light to a photosensor;
• and
• more than 50% of the scintillator elements have grooves along the first side surface, wherein the grooves have lengths extending in a direction toward the photosensor surface;
• and
• a clear adhesive material adjacent to the scintillator elements.

A process of forming a scintillator array comprising:

• forming plates from a block of a scintillator material;
• placing a reflective sheet and a clear adhesive material between immediately adjacent plates;
• cutting a combination of the plates and reflective material into slices;
• and
• performing an activity including:
• forming first grooves along at least one surface of the plates, wherein the first grooves are oriented in a first direction that is substantially parallel to a centerline of the plates;
• forming second grooves along at least one surface of the slices, wherein the second grooves are oriented in a second direction that is substantially parallel to the centerline of the scintillator elements being formed;
• or
• both forming the first grooves and the second grooves.
