A high-resolution PET detector based on continuous scintillators

We have compared the performance of PET detector modules using continuous scintillator blocks with modules based on a large number of small crystal pixels. We show that a good spatial resolution can be obtained in undivided scintillators. One of the main advantages of the undivided scintillators is the excellent depth of interaction identification capability. There is almost no degradation of the spatial resolution upto incidence angles of 40degrees away from normal incidence. (C) 2004 Elsevier B.V. All rights reserved.
