Fig. 6From: Advanced 4-dimensional cone-beam computed tomography reconstruction by combining motion estimation, motion-compensated reconstruction, biomechanical modeling and deep learningComparison of DVFs solved by SMEIR, SMEIR-Bio and the Demons registration. The Demons registration was directly performed between the “Ground-truth” high-quality 4D-CT images.
