Elimination of motion artifact in breast MR imagesis a significant issue in pre–processing step before utilizing imagesfor diagnostic applications. Breast MR Images are affected by slowvarying intensity distortions as a result of contrast agentenhancement. Thus a nonrigid registration algorithm consideringthis effect is needed. Traditional similarity measures such as sumof squared differences and cross correlation, ignore the mentioneddistortion. Therefore, efficient registration is not obtained.Residual complexity is a similarity measures that considersspatially varying intensity distortions by maximizing sparseness ofthe residual image. In this research, the results obtained byapplying nonrigid registration based on residual complexity, sumof squared differences and cross correlation similarity measuresare demonstrated which shows more robustness and accuracy ofRC comparing with other similarity measures for breast MRimages.<\div>
