Review—Scintillators for Medical Imaging: A Tutorial Overview

Abstract

In this paper, we will review recent developments in scintillators, with a focus on scintillating materials for application in Computed Tomography (CT) and Positron Emission Tomography (PET). Main emphasis in the paper is on the translation of device requirements into material properties that need to be obtained. We will do this in particular to improve light yield (number of visible photons per keV of excitation energy), emission spectrum and decay time.
