Abstract
Systems and methods for image segmentation in generating computer models of a joint to undergo arthroplasty are disclosed. Some embodiments may include a method of partitioning an image of a bone into a plurality of regions, where the method may include obtaining a plurality of volumetric image slices of the bone, generating a plurality of spline curves associated with the bone, verifying that at least one of the plurality of spline curves follow a surface of the bone, and creating a 3D mesh representation based upon the at least one of the plurality of spline curve.
Claims16
A method of mapping a representation of a model bone into an image scan of a target bone:
- registering a generated portion of the representation into the image scan of the target bone using a translational transformation;
- registering the generated portion of the representation into the image scan of the target bone using a similarity transformation;
- registering a boundary portion of the representation into the image scan of the target bone using an affine transformation;
- and
- registering the boundary portion of the representation into the image scan of the target bone using a spline transformation.
