Abstract
The paper deals with design of complex simulation environment which is able to simulate on the base of mathematical techniques individual reconstructions methods which are normally used on Computed Tomography (CT). Primary attention is focused on The Single Back Projection technique (SBP) and The Filtered Back Projection (FBP). There is a significant benefit with comparison of normally used mathematical software. This simulation instrument is fully dynamic. Individual transformation methods are generated by form dynamic simulations which graphically explain the process of whole reconstruction procedure. The second part deals with simulation of Beam Hardening artifact. It is special type of artifact which significantly deteriorates CT images. This artifact is created especially on the surround of metal object. This simulation is important especially in term of manifestation of artifact. Simulation is helpful for design of filter for Beam Hardening suppressing as well. The complex simulation environment is performed in software MATLAB.
