Patent ID: 8907291

Claim:
A positron emission tomography (PET) detector module, comprising: an array of scintillation crystal elements; a plurality of photosensors arranged to at least partially cover the array of scintillation crystal elements and configured to receive light emitted from the array of scintillation crystal elements; and a transparent adhesive arranged between the array of scintillation crystal elements and the plurality of photosensors, the transparent adhesive extending directly from a surface of at least one of the scintillation crystal elements to a surface of at least one of the photosensors and configured to distribute the light emitted from one of the scintillation crystal elements to more than one of the plurality of photosensors, wherein the at least one photosensor has a width dimension, and the transparent adhesive, as measured in a direction extending from the at least one photosensor to the at least one scintillation crystal element, has a thickness of between 20% and 100% of a width dimension of one of the at least one photosensor.
