Kinematics of joints via three-dimensional MR imaging

We present a new methodology that enables us to mathematically model and quantify the motion of each component bone, relative motion of bones, the contact surface of bones and their change during motion for complex joints from a time sequence of MR image volumes. Additionally, since we model the bone surfaces, we are able to display in vivo joint motion. Through a variety of new rendering techniques we are able to create realistic displays of bones from MR images and to combine these displays with the display of motion parameters.
