Megjegyzések:	Elektronikus Osztály, MTA - Atommagkutató Intézet Background: The examination of small animals using high resolution in vivo imag- ing methods is a crucial tool in pharmaceutical research projects. Too suffice this demand, a full ring small animal PET camera (MiniPET-II) has been built in our Institute as part of succesive R+D projects. The aim of the study was to develop a complete hardware and software system supporting 3D PET-data acquisition, image reconstruction, image processing and evaluating the performance parameters of this scanner according to the guidelines of National Electrical Manufacturers Associations (NEMA) NU-4 standards. Material and methods: The fully modular MiniPet-II scanner consists of 12 detector modules in a single ring with LySO scintillator crystal blocks and position sensitive PNTs. Each crystal block comprises 35 x 35 pins of 1.27 x 1.27 x 12 mm size. Detector signals are processed by FPGA based digital signal processing boards with embedded Linux operating system. Results: Using cluster technique we have implemented a network based data aqui- sition system comprising embedded Linux environment of the detectors and data aquisition computer. A signal processing software controls the processing of the primary data. To support the image reconstruction, software was developed capa- ble of running either on multi-core computers, clusters and computers equipped with graphical processing units as mathematical co-processors. Performance pa- rameters were evaluated by NU-4 protocols. Conclusion: Based on the successful performance test measurements and the first biological studies the MiniPET-II scanner is an appropriate in vivo imaging tool sup- porting small laboratory animal investigations
