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.
Object reference: It is a reference to an object. Languages other than Java employ terms like pointer or address or. It is significant to keep the difference clear between an object and its reference. The variable like argo Q : Write a program that prints out 20 Write a program that prints out 20 random cards form a standard deck of 52 cards. Make sure the program prints out different sets of cards from one run to the next.

Function overloading in C++: The function name containing numerous definitions which are differentiable by the number or kinds of their arguments is termed as function overloading.
Race hazard: It is a situation which occurs between multiple threads sharing a resource. The race hazard occurs whenever one thread's suppositions regarding the state of a resource are invalidated by the actions of the other thread.
Reduce Concurrency: From a model-checking perspective, the searched state space consists of all possible thread-state combinations, which implies that the level of concurrency has the biggest impact on state space size. As a consequence, reducing conc
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.

Explain the main classes given by the .NET namespace to process the XML files.
Let assume seven PMTs situated around the origin of the x-y coordinates on the face of the Anger camera as illustrated in the figure. The size of the PMTs is 2mm by 2 mm and each PMT has been allocated a number. The single scintillation event yields a response from PM
