With an axial field of view of 200 cm and nine double-sided concentric SiPM ri ngs\, the system is designed for high-resolution\, whole-body imaging. Xen on doping enhances LAr scintillation by accelerating light emission\, supp ressing long-lived components\, and shifting the emission spectrum\, leadi ng to improved timing resolution and detection efficiency. Developed as a medical imaging application within the DarkSide dark matter search program \, the 3Dπ simulation framework is built on Geant4 and adapted from the D arkSide software suite. I will present recently published performance resu lts of the 3Dπ scanner based on the NEMA NU 2–2018 standards\, includin g spatial resolution\, sensitivity\, image quality\, count rate\, and timi ng performance. I’ll also provide a brief outlook on the project's futur e directions.\n\n \n\nAbout the speaker:\n\n Dr. Azam Zabihi has been a postdoctoral researcher at AstroCeNT in Warsaw\, Poland\, since Septemb er 2020\, specializing in detector development\, particle simulations\, an d medical imaging. She leads the 3Dπ PET project\, which focuses on a cry ogenic PET scanner based on xenon-doped liquid argon and SiPMs. Her backgr ound includes neutron radiation modeling\, Geant4-based simulations\, and contributions to the DarkSide-20k experiment.\n\n----------------\n\nMeeti ng ID 会议号: 93113366238\nMeeting URL 会议链接:: https://zoom.us/j /93113366238?pwd=zY97SctnAzdPLThBvibMXrtEPBVrkV.1\nHostKey 主持人密钥 : 018776\nPassword 会议密码: 250716\nhttps://indico.ihep.ac.cn/event/2 6701/ LOCATION:228 Multidisciplinary Building URL:https://indico.ihep.ac.cn/event/26701/ END:VEVENT END:VCALENDAR
