Characterization of the spatial resolution of the J-PET detector

Warsaw Medical Physics Meeting 2015

A prototype of the positron emission tomography device based on plastic scintillators is currently being developed at the Jagiellonian University [1-3]. Point Spread Function (PSF) determined for the detector with different scintillator shapes will be shown. PSF can be used both to determine and to improve spatial resolution in PET scanners [4]. Spatial resolution of the J-PET prototype was determined using two 22Na radioactive isotopes placed inside the detector. [1] P. Moskal, S. Niedźwicki et al., Nucl. Instr. and Meth. A764 (2014) 317.
