Computed Tomography (CT) is extensively used in the field of imaging to study the geometry, composition and mass density of interior organs by taking two-dimensional x-ray projections of the organs from which 3D images are reconstructed (Yazdi & Beaulieu, 2008; Barrett & Keat,… Presence of an artifact compromises the quality of the image generated from the scan, thus making it difficult to use the image as a diagnostic tool (Barrett & Keat, 2004).... There are several ways by which artifacts originate which include processes involving ct data ion, movement of patients during the scanning process or presence of metals on the body, problems with the scanner or during the reconstruction process (Barrett & Keat, 2004)....
