Abstract
The present disclosure describes methods and apparatuses for reducing metal artifacts in cone beam computed tomography (CBCT) reconstructions. The methods use multiple imaging modalities to identify and locate metal present in a region of dental patients mouth and to generate a reconstructed 3-D volume image of the region with reduced metal artifacts using data obtained by the multiple modalities. According to example embodiments, the methods include creating a metal map using data from a first imaging modality and an initial 3-D reconstruction from data obtained from a second imaging modality including CBCT imaging. The metal map is registered to the initial 3-D reconstruction with a reconstructed metal map and projection metal maps being subsequently produced and applied to projections from the CBCT imaging to generate interpolated projections. An artifact reduced 3-D reconstruction is produced from the interpolated projections and a final 3-D reconstruction is created therefrom including merged metal information.
