Abstract

Functional alignment of a 3D image of pelvis includes identifying a reference points on each 2D image of weight-bearing pelvis; identifying corresponding reference points on a 3D image of pelvis in a non-weight bearing position; constructing references on the 2D images based on the reference points on each respective image, constructing a corresponding reference on the 3D image based on the reference points thereon; and aligning the corresponding references of the 3D image with the references of 2D images, to provide a functionally aligned 3D image to more accurately plan placement of an acetabular shell. Another aspect of the invention determines an acetabular center of rotation (CoR) calculations for use in navigation during a THA surgery, including obtaining a point cloud of a surface of an acetabulum with a navigated instrument during the THA surgery; creating an acquired surface of the acetabulum based on the point cloud; extracting an acetabular CoR from the acquired surface for use in alignment and registration.
