Webb24 mars 2024 · The Radon transform is an integral transform whose inverse is used to reconstruct images from medical CT scans. A technique for using Radon transforms to reconstruct a map of a planet's polar regions using a spacecraft in a polar orbit has also been devised (Roulston and Muhleman 1997).

Webb20 sep. 2014 · The image reconstruction process used in these tomography techniques is usually based on the Radon transform (RT). In this paper, an algorithm based on Markov chain Monte Carlo methods for reconstruction of 2D–3D structures is introduced, including correction of noise directly from the RT sinograms. WebbThe inverse Radon transform is used in computed tomography to reconstruct a 2D image from the measured projections (the sinogram).
