In flat space, two parallel lines never meet, however, they appear to meet at very distances for the same reason due to which objects appear smaller when they are at a distance than when they are ...

In this case the 2D Radon transform is sampled for , , and , . Here is the radius of the reconstruction region, i.e. we assume f(x) = 0 for , . This means that the measured rays come in p parallel ...
