document: Image reconstruction of simulated specimens using convolution back projection This paper reports the reconstruction of cross-sections of composite structures . The convolution back projection -LRB- CBP -RRB- algorithm has been used to capture the attenuation field over the specimen . Five different test cases have been taken up for evaluation . These cases represent varying degrees of complexity . In addition , the role of filters on the nature of the reconstruction errors has also been discussed . Numerical results obtained in the study reveal that CBP algorithm is a useful tool for qualitative as well as quantitative assessment of composite regions encountered in engineering applications
