Digitized postoperative radiographs of the pelvis after total hip replacement are analyzed to measure the orientation of the artificial acetabular cup by matching the calculated projection to the xray image. Current research includes 2D/3D registration to match the xray image of the pelvis with the synthetic projection of the CT-scan, in order to precisely reconstruct the spatial position of the pelvis at which the xray was taken. This will allow precise and reliable measurements from xrays and create conditions for better analysis of postoperative outcomes.
