Trends and Challenges: A 15-Year Review of Imaging and Radiation Oncology Core Anthropomorphic Phantom Audits for Proton Therapy
Overall institutional phantom performance has not significantly improved over time. In particular, the proton lung and liver phantoms continuously demonstrate suboptimal results, likely due to complex geometries and motion management challenges. These findings underscore the need for careful selection of treatment parameters and optimization of motion management strategies. The IROC phantom program remains crucial for characterizing proton therapy systems and identifying clinically significant errors.
