Optical processing in radon space

Harrison H. Barrett

The Radon transform is the mathematical basis of computed tomography. In this important medical imaging technique, the basic data are a set of one-dimensional (ID) projections of a 2D object, obtained by integrating it along a set of lines. The projection process is called the 2D Radon transform, and reconstruction of the object from its 1D projection is an implementation of the 2D inverse Radon transform.
