Measuring the relative motion of the femur and tibia in a knee joint currently requires tantalum beads to be implanted into the bones. These beads appear as high-intensity features in radiographs and can be used for precise kinematic measurements. This procedure imposes a strong coupling between accuracy and invasiveness. Advances in ultrasound (US) sensor technology and the availability of micro-drives mean that it is now possible to construct a small and lightweight US sensor which can be...[Show more]
