Reconstruction of computed tomography with metal implants.
Computed Tomograghy has played a key role in bone structure imaging for over two decades. However, when a metal implant present in the sample, the reconstructions are seriously distorted by artefacts, and no method has successfully met the clinical demands. This paper presents a new method for partial reconstruction in Computed Tomography. The metal implant is reconstructed separately and the correspondence is isolated from the projection. The boundary between the metal implants and other tissues are clearer. The method is demonstrated by experiments.
