55. CRYSP: towards an accessible TBPET

Laura Navarro-Cozcolluela (DIPC)

Nowadays, the bulk of the cost in TBPET systems comes from the scintillator, followed by SiPMs and electronics. Commercial TBPET scanners typically use LYSO, which is very expensive and relies on rare-earth elements whose production and manufacturing are geographically concentrated and supply-limited. Thus, the first priority of any putative low-cost TBPET is to find significantly cheaper...

Abstract:
The Jagiellonian Positron Emission Tomograph (J-PET) collaboration is developing a Total-Body PET system based on plastic scintillators, with silicon photomultipliers (SiPM) located at the strip ends, and gamma detection is achieved through Compton scattering [1]. Results presented at the PSMR 2024 conference included time-difference measurements for plastic scintillators of various...

31. Toward Total-Body Modular Flat-Panel TOF-PET Enabled by Sub-100 ps Timing

Rok Pestotnik (Jozef Stefan Institute (SI))

Total-body PET (TB-PET) offers transformative gains in sensitivity, dynamic imaging capability, and quantitative performance, but current implementations rely on extended axial full-ring geometries associated with high scintillator cost and system complexity. Within the PetVision project, we investigate an alternative paradigm in which extreme timing performance enables simplified, modular...

51. Towards Autonomous Position Calibration of PET Scanners using Physics-Based Neural Networks

PABLO GALVE LAHOZ (Institute for Physical and Information Technologies “Leonardo Torres Quevedo”, ITEFI, Spanish National Research Council (CSIC), Madrid, Spain)

The recent advent of Total-Body PET (TB-PET) represents a transformative leap in molecular imaging, offering an effective sensitivity gain of over 40-fold and enabling full-body dynamic tracking [1, 2]. To maintain uniform spatial resolution across such extended fields of view, precise Depth-of-Interaction (DOI) capability is crucial to mitigate severe parallax errors. Advanced light-sharing...

57. Investigation of the Sensitivity of a Brain PET Insert in a Total-Body J-PET System: A Simulation Study

Prof. Pawel Moskal (Jagiellonian University), sharareh jalali

14/05/2026, 11:50

Positron emission tomography (PET) is a powerful molecular imaging tool that detects functional and biochemical changes in tissues before structural abnormalities become visible,making it invaluable for early diagnosis, disease characterization, and treatment planning and monitoring [1]. Sensitivity is a critical determinant of PET image quality and is significantly enhanced in systems with a...
