Quantification of the aperture modulation in radiotherapy treatment plans.

ABSTRACT:

Background

Many international guidelines, including those from the American Association of Physicists in Medicine (AAPM), emphasize the importance of quantifying plan modulation and recommend clearly documenting the modulation amount and range of radiotherapy treatment plans. However, there is no standardization or consensus on how to quantify plan modulation, partly due to the limitations of existing metrics.

Purpose

This study introduces two novel metrics to quantify the modulation of treatment plans: the plan aperture modulation (PAM) and the modulation factor (MF). The aim of these metrics is to provide a clear and intuitive assessment of the aperture modulation in radiotherapy plans, addressing limitations of previous metrics and facilitating integration into treatment
