DOI: 10.1002/acm2.12988
Abstract: Abstract Purpose Deformable image registration (DIR) in low‐contrast tissues is often suboptimal because of low visibility of landmarks, low driving‐force to deform, and low penalty for misalignment. We aim to overcome the shortcomings for improved… read more here.
