The 3DΠ project, developed in collaboration with DarkSide, introduces a novel Total-Body (TB), Time Of Flight (TOF), Positron Emission Tomography (PET) scanner for medical imaging. This project builds upon the advancements made by the DarkSide collaboration in Liquid Argon(LAr) detector technology, low-radioactivity argon procurement, and cryogenic photosensor development.
The 3DΠ scanner incorporates a cutting-edge scintillator system that utilizes Xenon-doped Liquid Argon (LAr+Xe) and Silicon Photomultiplier (SiPM) panels. By adding Xenon doping, the long-lifetime component of the scintillation light is effectively reduced, allowing for higher data rates. This approach enables faster processes compared to other methods involving a wavelength shifter. Additionally, cooling the SiPMs to match the temperature of LAr significantly reduces the dark count rate within the SiPM. In our talk, we will primarily focus on the concept design and advantages of the 3DΠ scanner, including the standardized NEMA performance results.
Preliminary findings from NEMA tests indicate that the performance of our scanner's system is comparable, if not superior to, other commercial scanners. By emphasizing the innovative design and key advantages of the 3DΠ scanner, we aim to convey the potential impact of this technology in the field of medical imaging.
