| contents | Development of a Simulator for Tomographic Images Generated by Radiation Transmission Gevaldo L. de Almeida Maria Ines Silvani Ricardo T. Lopes Marcelo J. Gonçalves Rosanne C. A. A. Furieri Física, Astronomía y Matemáticas A computer program to simulate tomographic images generated by transmitted radiation was developed. Thealgorithm uses a deterministic approach to generate the projections, which supply an existing image reconstructionsoftware. A dispersion associated with the counting statistics is also incorporated into the algorithm,in order to simulate the influence of the detector efficiency and counting time on the final image quality. Thedetector resolution is also included in the algorithm by assuming a gaussian shape for its line spread function -LSF. The program deals with cylindrical objects containing any desired number of cylindrical rods inside andrequires their positions, dimensions and attenuation properties as input data. Images of such objects, acquiredwith a thermal neutron tomograph equipped with a position sensitive detector, have been compared with thosesimulated by the developed program in order to evaluate its ability to reproduce those images. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46434515 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3A Vol.34 |
