High Resolution Imaging with ClearPET Neuro - First Animal Images

The ClearPET/spl trade/ Neuro is the first full ring scanner within the Crystal Clear Collaboration (CCC). It consists of 80 detector modules allocated to 20 cassettes. LSO and LuYAP:Ce crystals in phoswich configuration in combination with position sensitive photomultiplier tubes are used to achieve high sensitivity and realize the acquisition of the depth of interaction (DOI) information. The complete system has been tested concerning the mechanical and electronical stability and interplay. Moreover, suitable corrections have been implemented into the reconstruction procedure to ensure high image quality. We present first results which show the successful operation of the ClearPET/spl trade/ Neuro for artefact free and high resolution small animal imaging. Based on these results during the past few months the ClearPET/spl trade/ Neuro System has been modified in order to optimize the performance.
