Conclusion: PAM is a novel and comprehensive metric for quantifying modulation in radiotherapy plans. It overcomes the limitations of previous metrics and can be readily implemented in TPSs to control plan modulation during optimisation and for reporting. This is achieved by considering not only the plan parameters but also the geometry of the problem, enabling a robust and intuitive assessment of IMRT/VMAT plan modulation. PAM is a promising tool for improving treatment planning workflows and for comparing and benchmarking radiotherapy plans. Its outstanding features make it promising also for multi-institutional studies, including clinical trials and audits.
