Abstract :
The aim of this paper is to compute the discrete inverse Radon transform over Rn. The Radon transform is a function with domain Sn-1×R. It is shown that under different measures this function can be defined with domain R n. In this case one can compute the discrete inverse Radon transform in a Cartesian coordinate system with no need to interpolation between polar and Cartesian grid or the use of a backprojection operator
