The 3D representation of CT scans is widely used in medical application such as virtual endoscopy, plastic reconstructive surgery, dental implant planning systems and more. Metallic objects present in CT studies cause strong artifacts like beam hardening and streaking, what difficult to a large extent the 3D reconstruction. Previous works in this field use projection data in different ways with the aim of artifact reduction. But in DICOM-based applications this information is not available, thus the need for a new point of view regarding this issue. Our aim is to present an exhaustive study of the state of the art and to evaluate a new approach based in mathematical morphology in polar domain in order to reduce the noise but preserving dental structures, valid for real-time applications.
