Contour-Constrained Deformable Registration with Parameter Characterization for Head and Neck Surgical Guidance
Researchers have developed a new deformable registration framework to improve surgical guidance for head and neck cancer operations. This method uses Kelvinlet basis functions and contour constraints to correct for tissue deformation and shrinkage that occurs after resection. The technique significantly reduced registration error compared to rigid methods, particularly for challenging tongue specimens, and a parameter search indicated contour weighting is crucial for accuracy in highly deformable tissues.
