The development of the CT-Scans, has proved to be one of the great leaps forward in diagnostic medicine and for medical research. Interestingly enough the concept was started by a Mathematician - Johnann Radon (1887-1956) who while investigating the idea of reconstructing the value of a function at a point in a plane region by computing the sums of the values of this function along lines that intersected this domain arrived at the conclusion which in today’s world Mathematicians refer to as the Radon Transform. It belongs to the area of reconstruction of information from partial knowledge, or from "samples" of various kinds. Radon showed that the unknown densities could be reconstructed from the "line integrals" and this formed the basis of the developing computer code to improve the image quality for the current CT – Scans that we use.
