摘要
An auto-contouring performance measure (e.g. DICE coefficient, Jaccard index, Hausdorff distance, mean distance to agreement) is computed (335) for each candidate atlas n within the set of N candidate atlases (110) in relation to each training atlas t within a subset of a set of T training atlases (330). For each pair combination of n and t for which a measure has been computed, a score (e.g. relative weighting, absolute weighting, editing time prediction value) is derived (360) based on the computed measures. The derived scores are aggregated (365) for each candidate n within the set N for each pair combination comprising that candidate atlas n. A subset of M atlases is selected (370) from the set of N atlases based on the aggregated scores (e.g. those with the most favourable scores) which can be used by medical image auto-contouring systems. Auto-contouring performance measures may be computed for each of a plurality of structures of each atlas n within the set N in relation to each training atlas t, and a score may be derived for each of the plurality of structures, e.g. partly based on a structure weighting value. An atlas is a medical image with previously delineated structure(s).
