  1. Region specific average Jacobian values of the computed deformation for different approaches and ten cases. “VSA”: Varian SmartAdapt deformable registration; “REG0”: new approach without local rigidity; “REG1”: new approach with rigid bones; “REG2”: new approach with rigid bones and prostate; “Avg”/“Std”: average/standard deviation over all cases for each method and structure
