Abstract

Provided are a device for detecting sub-atomic particles and a method of fabrication thereof. The device includes a plurality of scintillators, a detector provided on a first end of the plurality of scintillators and a prismatoid provided on a second end of the plurality of scintillators. The prismatoid redirects light between adjacent scintillators of the plurality of scintillators.

Description

[0001] priority [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 789,559, filed January 8, 2019, with the USPTO and 62 / 957,991, filed January 7, 2020, the entire contents of which are hereby incorporated by reference into this article. [0003] governmental support [0004] This invention was made with government support under NIH grant number EB024849. The government has certain rights in this invention. technical field [0005] The present invention relates generally to the field of radiation imaging, and in particular to positron emission tomography (PET). Background technique [0006] PET is a nuclear medicine imaging technique that produces three-dimensional (3D) images to see processes in living tissue. PET is commonly used in clinical oncology to detect cancer and clinically to diagnose heart problems and / or brain disorders. Positron-emitting radionuclides introduced into organisms emit two photons in diametrically opposite dire...
