Image reconstruction of simulated specimens using convolution back projection

[摘要] This paper reports about thereconstruction of cross-sections of composite structures. Theconvolution back projection (CBP) algorithm has been used to capture theattenuation field over the specimen. Five different test cases havebeen taken up for evaluation. These cases represent varying degrees ofcomplexity. In addition, the role of filters on the nature of thereconstruction errors has also been discussed. Numerical resultsobtained in the study reveal that CBP algorithm is a useful tool forqualitative as well as quantitative assessment of composite regionsencountered in engineering applications.
