1. Write a MATLAB program that reconstructs the phatom image from its projections using the back projection method.Your program should allow the user to input any phantom object like P and a set (e.g. vector) of projection angle, e.g. Theta=[0:0.1:pi]. Your program should then:

-compute the sinogram of the object (you can use Matlabs radon.m command to do this).

-compute the reconstructed image from the sinogram and vector of projection angles.
