Abstract

This study uses Computed Tomography (CT) for reconstructing images of solid propellant rocket motors during static firing tests. Implementation, verification and comparison of four CT algorithms are presented. These four algorithms are: Algebraic Reconstruction Technique, Linear Superposition with Compensation, and Fourier Convolution technique with parallel beams and fan-beam. The phantom used in the comparison between algorithms is similar in cross-section to a solid propellant rocket motor. Comparison between algorithms on the ability to detect artifacts is made. Also, a comparison is made using data obtained by optical tomography of the absorption coefficient inside a 20 mm gas gun barrel. Finally, a comparison of the running time versus number of projections, number of ray sums, and resolution is studied.
