Abstract
Abstract We show that discrete tomography (DT) is suitable to increase the possible inspection size of single material oblong objects compared to filtered back projection (FBP) in non-destructive testing (NDT) with 2D X-ray computed tomography (CT). For such objects which are in one dimension larger than the maximum detectable material thickness limited view angles occur and FBP is not suitable for reconstruction. For evaluation of the reconstruction performance a copper phantom (strong absorber) which exhibits typical problems for NDT was manufactured. The increase of the object size with DT reconstruction compared to FBP was estimated to be above 50%.
