Translational X-Ray Tomographic Approach to Narrow-Angle Scanning of Objects

Research output: Contribution to journalArticlepeer-review


An X-ray tomographic scanning method is proposed based on a combination of the angular and translational approaches. The reconstruction algorithms have been used for simple geometric primitives like the twodimensional Shepp–Logan phantom (standard test specimen) and a specimen in a tomographic experiment. The specimens were reconstructed using rotational, translational, and combined limited-angle tomographic scanning. The applicability and the advantages of the proposed approach have been demonstrated compared to other standard scanning approaches. In addition, it is shown that the proposed approach allows 2D and 3D objects to be reconstructed quickly and efficiently. The quality of visualization is a function of the number of angular and translational positions that determine the experimental scanning time and must be selected individually for each physical object to be scanned. This approach provides a fast and informative analysis of various objects in case of failure of standard approaches.
