A local phase-based algorithm for registration of CMR scans from multiple visits

A variational 3D phase-based registration approach for the alignment of reconstructed cine volumes from short- and long-axis cine CMR slices is proposed. The algorithm performance is validated comparatively with an equivalent intensity-based approach on an artificially generated phantom volume with a pre-prescribed intensity difference. Final results are shown for the registration of clinical cine CMR volumetric alignment.
