(A) CBCT projections of the instrumented tibia phantom for a range of axial loading conditions. Amount of load increases from Cfg.0 to 5. The green overlays are DRRs of the estimated deformed implant obtained with FFD-KC-Reg from three projection views. (B) Estimated displacement of the deformed point cloud relative to the point cloud of the undeformed implant model. The white point cloud in the left image is the undeformed prior model, and the yellow point cloud is the estimated deformed model.
