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.

For loop: This is one of the Java's three control structures employed for looping. The other two are while loop and do loop. A for loop includes of a loop header and a loop body. The header comprises of three expressions separated by two semicolons an
Port: It is a number employed by a procedure to communicate with the other procedure across a network, employing the Transmission Control Protocol (abbreviated as TCP) or User Datagram Protocol (abbreviated as UDP), for instance.
Inheritance: It is a feature of object-oriented programming languages in which a sub-type inherits methods and variables from its super-type. The Inheritance is most generally employed as a synonym for class inheritance {class!inheritance}, however in
