Abstract

Different designs of high-resolution positron camera systems have been investigated. The design goal is an instrument that can measure the whole brain with a spatial resolution of 5 mm FWHM in all directions. An overall spatial resolution of 5 mm requires crystal dimensions of 6 x 6 x L mm3, or less, L being the length of the crystal. Timing and energy requirements necessitate high-performance photomultipliers. The small size scintillator crystals can currently only be read in schemes based on Anger techniques or by utilizing surface-sensitive PMTs. In the future, photodiodes can replace photomultipliers. In the present work, two different approaches have been investigated: Anger techniques and position-sensitive PMTs. Preliminary results of the two detector designs are reported.
