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.
Write a program to print out ten random numbers from the following sets: a) {0, 1, 2, 3, 4, 5, ...99, 100} b) {1, 2, 3, 4, 5, 6} c) (10, 20, 30, 40, 50,...990, 1000} d) {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5} e) {1.5, 2.0, 2.5, 3.0, 3.5}

What is Character Set. Briefly explain it?
Memory leak: It is a situation in which memory which is no longer being employed has not been returned to the pool of free memory. The garbage collector is designed to return unreferenced objects to the free memory pool in order to shun memory leaks.<
Normal 0 false false
Hot spot: This is an area in an image map with a specific significance. A program usually monitors movements of the mouse, and reacts according to the actions related with the hot spots over which it passes. This may comprise displaying various status
State: The objects are said to possess state. The present state of an object is symbolized by the joint values of its attributes. Protecting the state of an object from unsuitable inspection or modification is a significant aspect of class design and
Leverage Model-Based Design: Model-based design provides useful hints of how a large system can be reduced so that its state space becomes searchable. If not inherently visible in the design (for example, by means of using a “State” design
