I have a 4 D CT set with joint movement. I am trying to analyse the 3 dimensional movement of bones as the joints move. I am using image registration and transform sequence to compute the displacement. My problem is I cannot use rigid registration - then the all the bones move as one block. If I use B spline- then its as if a soft tissue registration- the bone do not behave as rigid bodies.
How can I develop constraints that bone get registered as rigid bodies and the space inbetween bones get registered with B spline or similar way.
Thanks a lot
