Selection of a subset of atlases from a set of candidate atlases

摘要

A method and apparatus for selecting a subset of atlases from a set of candidate atlases. The method comprises: for each candidate atlas n within the set of N candidate atlases, computing an auto-contouring performance measure in relation to each training atlas t within a subset of a set of T training atlases; for each pair combination of candidate atlas n and training atlas t for which an auto-contouring performance measure has been computed, deriving a score based on the computed auto-contouring performance measures; for each candidate atlas n within the set of N candidate atlases, aggregating the derived scores for each pair combination comprising that candidate atlas n; and selecting a subset of M candidate atlases from the set of N candidate atlases based on the aggregated scores therefor.
