X-ray localization technique for total hip replacement operation in augmented reality for therapy (ART)

摘要

A novel approach for the localization of acetabular prosthesis cup placement, using X-ray images, in total hip replacement operation is described. A computational mathematical model is given and simulation results are presented. This informationhelps the orthopaedic surgeons to know the position of the hip in world coordinate system and direct him to the right position of implant insertion tool, viewing through a capture and display unit X-ray localization can be used both preoperatively andintraoperatively. Ability to use X-ray intraoperatively is the major advantage of our proposed technique.
