BACKGROUND: The significant limitation of simple volume analyses for target volumes is that they disregard the spatial distribution of non-overlapping volumes and the surrounding dose gradient. PURPOSE: ). METHODS: was evaluated via the Jaccard coefficient (JC) and dice similarity coefficient (DSC) and was compared against traditional indices in an illustrative case and two sets of volumes delineated at different time points. RESULTS: of two volume sets were 0.929 and 0.963, respectively. CONCLUSIONS: effectively incorporates the spatial location of non-overlapped volumes and key radiotherapy requirements.
