Non-rigid image registration with anatomical structure constraint for assessing locoregional therapy of hepatocellular carcinoma

Highlights • Propose nonrigid registration for quantitatively assessing the treated region with LT. • Edit the anatomical landmarks as constrained for maintaining the internal structure. • From the viewpoint of physics, the landmarks carry the energy in displacement field. • The proposed method achi...
