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.

Use Polymorphism: Programs, especially those converted from non-OOP languages like C, sometimes use state where they should use inheritance. For example, Q : Inventory management system in UML Mini-Case The Hatcher Company is in the process of developing a new inventory management system.

Try statement: The try statement performs as an exception handler - a position where exception objects are caught and dealt with. In its most common form, it comprises of a try clause, one or more catch clauses and the finally clause.
Deep copy: It is a copy of an object in which copies of all the object's sub-components are also prepared. The resultant object may, in effect, be a clone of the novel.
Native Mode: Whenever all the domain controllers in a specified domain are executing Windows 2000 Server. This mode permits organizations to take benefit of new Active Directory features like Universal groups, nested group membership, and the inter-do
Interpretational inner class: It is an inner class whose role is to give a view or interpretation of data belongs to its enclosing class, however independent of the data's real representation.
