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.

Property Specifications: The most straightforward way to specify and check simple safety properties in JPF is to use Java assertions inside the application under analysis. This allows the specification of properties that only depend on the application
1. Here is a short program. It prints out the value of a variable "x". Ernie and Bert disagree about what will be printed: Ernie says, the value gets changed in "changeX" so it will print "7", and Bert says, no, when the function exits the changes get reversed and the value goes back to "5". Expl

Anonymous class: It is a class formed without a class name. Such a class will be a sub class or an implementation of an interface, and is generally formed as an actual argument or returned as a method outcome. For example: Q : Create a BottomUpTwoThreeFourTree class You will need to create a BottomUpTwoThreeFourTree class, with a BottomUpTwoThreeTreeFourTree constructor which keeps no parameters. BottomUpTwoThreeTreeFourTree will require an insert(int x) method, which will insert the value
