J-PET: A New Technology for the Whole-body PET Imaging

Abstract

The Jagiellonian Positron Emission Tomograph (J-PET) is the first PET built from plastic scintillators. J-PET prototype consists of 192 detection modules arranged axially in three layers forming a cylindrical diagnostic chamber with the inner diameter of 85 cm and the axial field-of-view of 50 cm. An axial arrangement of long strips of plastic scintillators, their small light attenuation, superior timing properties, and relative ease of the increase of the axial field-of-view opens promising perspectives for the cost effective construction of the whole-body PET scanner, as well as construction of MR and CT compatible PET inserts. Present status of the development of the J-PET tomograph will be presented and discussed.

A feasibility study of the time reversal violation test based on polarization of annihilation photons from the decay of ortho-Positronium with the J-PET detector

“…The Jagiellonian -Positron Emission Tomograph (J-PET) is the first PETscanner constructed using plastic scintillator strips to make the tomograph cost effective and portable [9,10,13]. One of the unique features of the J-PET detector is its ability to measure polarization of the annihilation photons.…”

“…The J-PET detector consists of 192 plastic scintillator strips (EJ-230) of dimensions 500 × 19 × 7 mm 3 each, forming three concentric layers (48 modules on radius 425 mm, 48 modules on radius 467.5 mm and 96 modules on radius 575 mm) ( Fig. 1) [13]. Each scintillator in the J-PET scanner is optically connected at two ends to Hamamatsu R9800 vacuum tube photomultipliers [10].…”

“…The J-PET detector, together with the trigger-less DAQ system constitutes an efficient photon detector with high timing properties [13]. This allows us to investigate the fundamental discrete symmetries in the purely leptonic sector [8].…”

A Method to Produce Linearly Polarized Positrons and Positronium Atoms with the J-PET Detector

“…The Jagiellonian positron emission tomograph (J-PET) is the first positron emission tomography scanner based on organic scintillators and a prototype of a costeffective scanner for the simultaneous metabolic imaging of the whole human body [15]. The J-PET prototype consists of 192 detection modules, each equipped with photomultipliers (PMTs) on both ends and arranged axially in three layers forming a cylindrical diagnostic chamber with the inner diameter of 85 cm.…”

Simulation studies of annihilation-photon’s polarisation via Compton scattering with the J-PET tomograph

“…Keywords Compton Scattering; J-PET; Polarization 1 Introduction J-PET is a multipurpose detector designed for the development of medical imaging [1,2,3,4], for studies of discrete symmetries in decays of positronium atoms [5], as well as for investigations of multipartite quantum entanglement of photons originating from positronium annihilation [6,7]. J-PET is built from 192 plastic scintillator strips arranged axially in three cylindrical layers [8]. The cross section of the detector is shown in the left panel of Fig.…”
