The purpose of the presented research is estimation of the performancecharacteristics of the economic Total-Body Jagiellonian-PET system (TB-J-PET)constructed from plastic scintillators. The characteristics are estimatedaccording to the NEMA NU-2-2018 standards utilizing the GATE package. Thesimulated detector consists of 24 modules, each built out of 32 plasticscintillator strips (each with cross section of 6 mm times 30 mm and length of140 cm or 200 cm) arranged in two layers in regular 24-sided polygoncircumscribing a circle with the diameter of 78.6 cm. For the TB-J-PET with anaxial field-of-view (AFOV) of 200 cm, a spatial resolutions of 3.7 mm(transversal) and 4.9 mm (axial) are achieved. The NECR peak of 630 kcps isexpected at 30 kBq/cc activity concentration and the sensitivity at the centeramounts to 38 cps/kBq. The SF is estimated to 36.2 %. The values of SF andspatial resolution are comparable to those obtained for the state-of-the-artclinical PET scanners and the first total-body tomographs: uExplorer andPennPET. With respect to the standard PET systems with AFOV in the range from16 cm to 26 cm, the TB-J-PET is characterized by an increase in NECRapproximately by factor of 4 and by the increase of the whole-body sensitivityby factor of 12.6 to 38. The TOF resolution for the TB-J-PET is expected to beat the level of CRT=240 ps (FWHM). For the TB-J-PET with an axial field-of-view(AFOV) of 140 cm, an image quality of the reconstructed images of a NEMA IECphantom was presented with a contrast recovery coefficient (CRC) and abackground variability parameters. The increase of the whole-body sensitivityand NECR estimated for the TB-J-PET with respect to current commercial PETsystems makes the TB-J-PET a promising cost-effective solution for the broadclinical applications of total-body PET scanners.
