radiosteriometric analysis is a method to find metal implants implanted in bone over time. I am doing research on micromotion of knee implant in osteoporotic patients over two years by comparing the distance between metal implant and bone markers placed during surgery. markers are fixed. of implant moved over time i will find it by the change of distance. how to do this, and what extension to be used
