Simulation of artifacts in CT using MATLAB
How is Simulation of artifacts in CT is done utilizing MATLAB?
Expert
Supposing that one of detectors (at l = l0) of a CT scanner is malfunction, which forever outputs a value of 0, i.e. g(l0, θ) = 0. The malfunctioned detector locates below the object however not in the center of the detector array as illustrated in the figure. The parallel ray geometry is supposed.(1) If the projections are obtained with this CT scanner, display the sinogram for the object employed in Q1. (2) Apply the inverse Radon transform to projections to re-construct the object. Display the re-constructed image.(3) Discuss what types of artifacts are examined in the reconstructed image and what a technician must do to avoid such artifacts?(4) In the inverse Radon transform (that is, ‘iradon’), use a distinct filter (that is, the default filter is Ram-Lak) and dispaly the reconstructed image. Discuss how and why the re-constructed image is enhanced.
