Description
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 wide axial field of view (AFOV).
This study aims to evaluate and compare the sensitivity of a total-body J-PET system and a plastic-based brain PET scanner, as well as to investigate the combined sensitivity achieved when the brain scanner is integrated into the whole-body system.
Monte Carlo simulations were performed using the GATE platform to model the Jagiellonian Positron Emission Tomograph (J-PET), a next generation total-body PET prototype with an AFOV exceeding 250 cm, constructed from cost-effective plastic scintillators rather than conventional crystal-based detectors [2, 3].
The simulated sensitivity results for both standalone and integrated configurations will be presented at the upcoming conference, providing insight into the performance potential of plastic scintillator based PET systems for broad clinical and research applications
