Description: This example shows how to scan an image with a limited angle, obtain the sinogram, add noise to make things worse, and reconstruct the initial image with great accuracy
%You may want to remove/edit some sections if you intend to apply this to your use case:
%- skip/correct normalization
%- skip noise
%- use FBP for the iradon
