Simulation of artifacts in CT using MATLAB
How is Simulation of artifacts in CT is done utilizing MATLAB?

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.
Block: The statements and declarations are enclosed between a matching pair of curly brackets ({ and }). For example, a class body is a block, as it is a method body. The block surrounds a nested scope level.
Initializer: A block stated at the outermost level of a class - identical to a method devoid of a header. The initializer blocks are executed, in order, whenever an instance is formed. They are executed prior to the constructor of the defining class,
Expression: It is a combination of operands and operators which generates a resultant value. Expressions contain a resulting type that affects the context in which they might be employed.
