Abstract: | The aim of this paper is to compute the discrete inverse Radon transform over
n
. The Radon transform is a function with domainS
n–1× . It is shown that under different measure this function can be defined with domain
n
. In this case one can compute the discrete inverse Radon transform in the Cartesian coordinate system without interpolating from polar to Cartesian coordinates or using the backprojection operator. |
