Patent ID: 7646936

Claim:
An image registration system comprising: a deformation engine comprising: first logic configured to compute a flexibility model comprising a first set of spatially variant constraints or spatially variant scalars and to apply the computed flexibility model to a medical deformable image to generate a set of displacement vectors, the set of displacement vectors being configured to apply a first force to the medical deformable image; second logic configured to compute a non-Gaussian smoothing function and to apply the computed non-Gaussian smoothing function to the set of displacement vectors to create a smoothed set of displacement vectors; third logic configured to compute a transform, the transform being configured to apply a second force to the medical deformable image, the second force opposing the first force; and fourth logic configured to apply the smoothed set of displacement vectors and the transform to the medical deformable image to deform the medical deformable image to match a reference image.
