Some in-vivo and in-vitro US scans, (a)-(d) in-vivo scans of the lateral femur of a human subject, (e)-(h) in-vivo scans of tibia, (i)-(l) US scans of a model femur, and (m)-(p) US scans of a model tibia. The anatomical details are clearly visible in those scans, and this is crucial for non-invasive kinematic analysis.
