Abstract
An accurate depth location of pelvic land mark could be affected by the acoustic properties of the penetrated tissues and improper depth estimation could lead to a miscalculation of the acetabular cup implant. In the case of obese patient it is very difficult to locate the place of damage. Errors in land mark location leads to the improper treatment by orthopedic surgeons. The aim of this system is to determine pelvic orientation from CT scan images based on patch statistical shape model multilevel measurement utility tools by image calibration system; by applying a hierarchical registration scheme. Here a plastic bones and cadaveric specimen are used. Many approaches have been proposed in the literature to replace the percutanesous digitization, Involvement of the experts in the system to give the solution or conclusion.
