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
