Abstract

THE γ-INDEX CONCEPT INTRODUCED by Low et al. [1] has been widely used to compare two dose distributions in cancer radiotherapy. With the recently developed and more sophisticated treatment modalities such as volumetric-modulated arc therapy (VMAT) [2], the comparison of three-dimensional (3D) dose distributions becomes necessary in patient-specific treatment plans quality assurance (QA). However, comparing two 3D dose distributions is still a time-consuming (e.g., many minutes) task, because of the involvement of computational intensive tasks such as interpolation of dose grid and exhaustive search. There is a clinical need to significantly speed up 3D γ-index computations.
