An investigation into the effectiveness of various advanced CT methods in the reduction of metal artefacts

M Dixon

Plymouth Hospitals NHS Trust (Derriford Hospital)


Metal artefacts are a well known issue in many areas of CT, with scans involving stents, coils and artificial joints representing a significant majority. The theory behind both typical artefacts and advanced CT methods which can potentially reduce them is described and a summary of the results acquired using a specifically designed phantom presented. This will involve the use of a GE HD750 series CT scanner with the use of Model Based Iterative Reconstruction (VEO), Advanced Statistical Iterative Reconstruction (ASIR), rapid kV switching dual energy scanning (Gemstone Spectral Imaging) and high definition scanning.
