RATIONALE AND OBJECTIVES Accurate registration of computed tomography (CT) images to the patient is crucial for computer-assisted surgery. Markers used in roentgen stereo-grammetric analysis (RSA) can be located in a CT scan using a novel approach and also can be located physically. Roentgen stereo-grammetric analysis data act as "ground truth" for the three-dimensional marker locations. METHODS Two foam-bone phantoms were marked. The markers were scanned seven times with RSA, three times… CONTINUE READING
