Description
Total-body PET imaging is one of the most exploited topics in medical imaging. State-of-the-art PET scanners use inorganic scintillators such as L(Y)SO or BGO. We report the performance comparative studies of the total-body PET scanners using Jagiellonian PET (J-PET) technology that is based on the plastic scintillators. Four realistic total-body scanner geometries, varied in the number of rings, scanner radius, and distance between the neighbouring rings were considered. Monte Carlo simulations of two NEMA phantoms (2-meter sensitivity line source and image quality) were generated to assess the performance of the tested geometries. Significant differences in the sensitivity of the scanners were observed. At the same time, relatively small differences in the image quality metrics of the reconstructed NEMA IEC phantoms images were found. The optimal scanner design was recommended for the next generation of the J-PET total-body devices.
