| Abstract: Computed tomography is a technique for estimating the interior of an object from measurements of radiation collected around the object. This radiation is projected either through or emitted from the object and the projections are reconstructed to form the object image. The reconstruction quality & time depend on many factors such as: filteration domain, filter type and interpolation level. The objective of this paper is to develop an algorithm to simulate CT image reconstruction from projections (image simulated projections or raw data projections file).The developed program enables the user to investigate the effects of many factors mentioned above on the quality of the reconstructed images. The system has agraphical user interface (GUI) to facilitate changing the effictive factors and measuring the performance of the reconstruction. This system helps for studying the CT reconstruction process by introducing many factors selections for development as well as for training | ||||
