Medical images from diagnostic tools like Computed Tomography (CT) and Magnetic Resonance (MR) offer detailed insights into internal anatomy but lack information on the patient's coordinate system during surgery. Traditionally, surgeons mentally align medical images with the patient's position in the operating room, making outcomes heavily reliant on their skill and focus. The advent of Computer Assisted Surgery (CAS) addresses these limitations by allowing a computer system to control surgical execution based on preoperative images. A significant challenge in CAS is registration, which involves aligning datasets to a common coordinate frame. This dissertation investigates a non-invasive registration technique using a high-resolution pulsed laser radar system in computer-assisted hip-joint replacement surgery. The approach captures 3D laser surface points of the anatomical area during the procedure and registers them to a 3D surface model derived from preoperative MR images. The registration analysis focuses on the hip-joint socket (acetabulum) and demonstrates that the technique remains robust even in the presence of spurious signals from the surgical site.
