Cím:	Development of a calibration software to study small animal -PET detetcor modules / S. A. Kis, L. Balkay, M. Emri, E. Németh, J. Molnár , I. Bagaméry, L. Trón
Dátum:	2005
Megjegyzések:	Background: We have developed a PET camera for small animal studies at the PET Center of the University of Debrecen. We apply LSO scintillation crystals in the detectors that are arranged in 8x8 matrices in each module, and use a position sensitive photomultiplier tube with an appropriate optical connection. The corner signals of PMT contain the crystal position and energy data of the events. We constructed four such detector-blocks and rotating them we will achieve tomo- graphical PET projection. Material and methods: The aim of our work is to develop special software in order to determine the detector parameters (such as energy discrimination levels, pin- crystal positions, etc.). The software will be capable of visualizing the calculated detector properties and restore them for a data acquisition software unit. The deve- lopment has been assisted using a MATLAB software package because it contains a lot of useful predefined methods, such as segmentation, high-level optimization algorithms, 2D and 3D visualization tools needed to achieve our goals. Results: During data processing, the deviation of parameters of individual crystal elements turned out to be considerably high, so it was essential to perform the appropriate normalization prior to starting small animal studies.
