In this work, an algorithm is proposed which uses planes, lines, and points for registration when point-set registration is not feasible. METHODS: The proposed algorithm matches points, lines, and planes in each coordinate system, uses invariant features for initial registration, and optimizes the registration iteratively. For validation, simulated data with known ground-truth and real surgical tool registration data using point-set registration as ground-truth were created to evaluate the algorithm{\textquoteright}s accuracy. RESULTS: The proposed algorithm is equally as accurate as point-set registration, and the difference between the registrations is less than the noise in the tracking system. CONCLUSION: The proposed algorithm is a viable alternative when point-set registration cannot be performed.</span></p>
