Description

The growing demand on PET methodology for a variety of applications ranging from clinical use to fundamental studies triggers research and development of PET scanners providing better spatial resolution and sensitivity. These efforts are primarily focused on the development of advanced PET detector solutions and on the developments of new scintillation materials as well. However in spite of tremendous efforts of the researchers the new instrumentation developments are mainly based on Lu containing scintillation materials introduced in the last century. LSO, LYSO, LuAP, LuYAP crystals still remain the best PET scintillators in spite of the recent developments of bright, fast but relatively low density bromide scintillators [1]. At the same time Lu based materials have several drawbacks which are high temperature of crystallization and relatively high cost compared to alkali-halide scintillation materials. Here we describe recent results in the development of new scintillation materials for PET application. In the research reported we aimed to achieve the following goals: 1) temperature decrease of the crystalline materials synthesis; 2) development of high Z complex compounds without Lu or with its partial replacement; 3) development of crystal growth techniques for shaped crystals to minimize losses of the material at the mechanical treatment. 1.
