Dynamic Registration Using Ultrasound for Anatomical Referencing

This paper proposes methods to circumvent the need to attach physical markers to bones for anatomical referencing in computer-assisted orthopedic surgery. Using ultrasound, a bone could be non-invasively referenced, and so the problem is formulated as the need for dynamic registration. A method for correspondence establishment is presented, and the matching step is based on three least-squares algorithms: two that are typically used in registration methods such as ICP, and the third is a form of the Unscented Kalman Filter that was adapted to work in this context. A simulation was developed in order to reliably evaluate and compare the dynamic registration methods.
