Metal artifact reduction and image processing of cone-beam computed tomography data for mobile C-arm CT devices
2011
A new method to reduce artifacts (MAR), produced by high-density objects, especially metal implants (MI), in X-ray CBCT is presented. MIs located in the field of view (FOV) result in artifacts influencing clinical diagnostics and treatments. The novel method reduces metal artifacts by virtually replacing MIs by tissue objects of the same shape. This corrected data can be reconstructed with significantly reduced artifacts. After reconstruction, the segmented 3D MIs were re-inserted into the
