2nd Total-Body J-PET General Meeting
📅 January 22 – 24, 2026
Krakow, Poland
Welcome
The primary goal of the J-PET collaboration is to develop technology for the first Total Body J-PET (TB-JPET) scanner based on a plastic scintillator: a scanner with a long axial field of view (FOV) that unifies the sensitivity advantages of total-body PET with a modular detector architecture to broaden clinical accessibility at a significantly reduced cost.
The J-PET collaboration's activities also include the development and testing of new radioisotopes for preclinical and clinical imaging, and the development and testing of new ligands and radiopharmaceutical carriers in cellular and animal models (in vitro, ex vivo, and in vivo).
The enhanced sensitivity of TB-JPET will not only enable low-dose or dynamic multi-organ imaging, but also meet the requirements of multiphoton imaging modalities, such as Positronium Lifetime Imaging (PLI), where the statistical requirements are higher than those of conventional PET. In recent years, different detector geometries have been investigated to compare and optimize their performance in standard two-photon and multi-photon imaging, towards the design of next-generation portable PET scanners.
The 2nd Total-Body J-PET General Meeting (January 22–24, 2025) is going to be organized for collaboration members to discuss the status of building the TB-JPET and to set the future goals and milestones. Building a TB PET is not merely a matter of achieving a longer FOV. It requires collaborative efforts in detector engineering, adapting the DAQ for real-time scans, calibration methods, event classification, image reconstruction algorithms, correction techniques, and validation strategies—particularly for multiphoton observables that have not been explored in conventional PET.
The meeting will be focused on the following topics:
- J-pet performance as standard PET scanner
- Correction techniques (attenuation, random, scattering correction) for J-PET
- Multiphoton DAQ and event classification in a trigger-less data readout environment
- Positronium Lifetime Imaging (PLI) with clinically relevant β++γ radionuclides and phantoms
- Production of different radionuclides suitable for PLI
- Development of Graphical User Interface for Data acquisition, calibration and handling
- Development of the J-PET simulation packages (Geant4, GATE), data analysis and image reconstruction software
- Exploring the quantum correlation studies in Ps decays produced in different media
- Modular J-PET application in proton beam range and as Compton Camera
- Application of modular J-PET detection units in fundamental physics experiments
- Characteristic performance of first prototype module of TB-JPET
- Status of mechanical design and commission of first TB-JPET ring
- Installation and commissioning of CT at Center of Theranostics
