This study proposes a compact and transportable cylindrical PET system for in-room use at particle therapy facilities. The system is designed to enable PET imaging immediately after irradiation while avoiding beam-induced damage, and to provide sufficient performance for small-animal imaging. It consists of 30 detector modules arranged in a cylindrical geometry with an inner diameter of 8.2 cm and an axial field of view of 16 cm. Each module incorporates CLS detectors using fast LGSO scintillators. The system can be integrated with the SIRMIO platform, allowing detectors to retreat during irradiation and be repositioned for prompt imaging. Its modular structure enables easy disassembly and transport. This design offers a practical solution for flexible, high-performance PET imaging in particle therapy environments.
