14.1  INTRODUCTION

Miniaturized imaging devices for γ-radiation have become increasingly important in medical and preclinical applications throughout the last decade. They commonly consist of two main parts: the radiation sensor and an (external) collimator. The sensor allows for a precise measurement of the position of interaction of incident γ photons in an optically dense medium (typically inorganic scintillation crystals). Its main parts are ...
