![]() ![]() Furthermore, due to the possibility of the positronium mean lifetime imaging guaranteed by the J-PET technology, its sensitivity based on the triple coincidence technique has been evaluated. ![]() At the same time sensitivity at the center of the tomograph can reach up to 124.1(1.0+/-1.1). Such results exceed the conventional PET systems (represented by the Biograph Vision) by a factor of ~4.5 and ~15 respectively. The obtained results demonstrate that the standard imaging total sensitivity achievable with the Total Body J-PET scanners equals to 25.92(05+/-04) for theĢ meter long two-layer tomograph and 84.74(0.9+/-1.1) for the 2.5 meter long fourlayer tomograph. #Kosmiczna synchronizacja software#Its principle of operation, as well as detailed validation by comparison with GATE software is presented in this work. Moreover, a Toy Monte-Carlo model has been developed as a simplified approach to the sensitivity investigation. In order to achieve this goal a simulation-based study was carried out with a use of the standard Monte-Carlo simulation software - Geant4 Application for Tomography Emission (GATE). CEUR Workshop Proceedings 2616, 2020, 53–62.The main aim of presented thesis is to investigate sensitivity of the Total Body J-PET scanners as a function of their axial field of view and inner module construction, as well as assessing the influence of the angular acceptance criterion (used for PET performance optimization) on this characteristic. et al.: Combined system of phase synchronization with increased order of astatism in frequency monitoring mode.
