Cover Story: Current medical deformable image registration (DIR) methods optimize the weighted sums of key objectives of interest (e.g., dissimilarity, deformation magnitude, and guidance error). Having one weight combination that yields high-quality results for any instance of a specific DIR problem (i.e., a class solution) would facilitate the clinical application of DIR. A multi-objective optimization approach for DIR removes the need for manual tuning of the weight combination, providing a set of high-quality trade-off solutions. Here, we employed an evolutionary machine-learning approach to compute a multi-objective class solution for DIR—a set of weight combinations that, when used on any instance of a DIR problem, yields multiple high-quality DIR outcomes. We applied this approach to DIR of breast MRIs. From this set, a preferred DIR outcome can be intuitively selected, potentially facilitating the use of DIR in clinical practice. View this pa
