Abstract: A PET scanner includes a scintillator block and a plurality of photodetectors, each of which has a field of view that includes a portion of the scintillator block. An optical element is disposed between the scintillator block and the plurality of photodetectors. The optical element has a first layer and a second layer. The first layer has a central region and a peripheral region separated by a first gap. The second layer has at least a first region and a second region separated by a second gap.

Abstract: A detector unit for a detector array includes a photo sensor array, a light guide, and a plurality of scintillator elements formed unitarily with the light guide, the scintillator elements configured to emit absorbed energy in the form of light, the light guide being configured to transmit the light received from at least one of the scintillator elements to a photo sensor, the light guide and the plurality of scintillators being formed from the same material, an area covered by the photo sensors being smaller than an area covered by the scintillator elements and a number of photo sensors being less than a number of scintillator elements. A detector array and a method of manufacturing a detector array are also described herein.
