ABSTRACT

This article deals with the iterative tomographic algorithm. This has been applied initially for the reconstruction of a Cos-Gauss phantom model object. Afterwards, only Cos phantom object considered this is equivalent as a flame in a rectangular furnace for radiation heat transfer problems. The intensity distribution field is obtained into a two dimensional plane and reconstruction algorithm is applied to it. Projections of the intensity field are interpreted as a path integral along a line in the appropriate direction. The integrals are calculated numerically and are assumed to represent as exact data. The reconstruction algorithm used in this work is maximum entropy technique (MENT). It is observed that as the number of projection increases maximum absolute error and root mean square error are decreases.
