Abstract
The possibilities of using a 3D tomograph with a size-limited recording screen for detecting randomly oriented crack-like defects in large industrial facilities have been investigated. Circular and spiral scanning schemes are considered, and the principal possibility of detecting defects in the case of two-pass spiral scanning and a recording screen covering half the field of view of the cross-section of the test object is shown. The performance of the 3D reconstruction algorithm for the selected scanning method has been demonstrated.
