Tomography - Lecture 2 - The Radon Transform
Показать описание
In this lecture we introduce the Radon transform, and we examine several properties, such as shifting and scaling. We develop exact formulas for the sinograms of ellipses and circles which can be used later to give precise descriptions of the sinograms determined from the Radon transform of phantoms.
