The Radon transform is an integral transform whose inverse is used to reconstruct images from medical CT scans. read more
Of course it does. Consider its' original motivation. Saying the Fourier transform is simply an abstraction seems (to me) like saying Navier-Stokes has no basis in reality. read more
The dual Radon transform is a kind of adjoint to the Radon transform. Beginning with a function g on the space Σ n, the dual Radon transform is the function ∗ on R n defined by ∗ = ∫ ∈ (). read more
