Model-based radiostereometric analysis (MBRSA) methods exploit, in most cases, feature-based 2D/3D registration. In this paper we focus on a feasibilty of the intensity-based 2D/3D registration approach applied in MBRSA. To evaluate the feasibility, we created a data set containing stereo pairs of both synthetic and real radiographic images of a metallic radius bone implant. Evaluation, we performed and present, reveals sucient accuracy of the intensity-based registration pipeline and its robustness to image artifacts. The results obtained using synthetic radiographs show comparable accuracy with the feature-based non-overlapping area (NOA) approach. The registration process using real X-Ray images did not require preprocessing of the input radiographs neither was significantly affected by the presence of the metallic bone screws. This study presents an introductory part of an ongoing research.
