Abstract�� It is well known that Industrial Computed Tomography (ICT) is hampered by the matter of time to acquire an image severely. A scan concept called RR (Rotation and Rotation) was argued to save the scan time of large components ICT testing with TR(Transverse Rotation). Its reconstruction algorithm based on filter back-projection algorithm was presented. The validity of the algorithm was proved by computer simulation results. Analysis indicated that the scan speed can be improved at least three times, compared with that of TR limited by the same testing conditions.
Keywords�� tomography   penetrating radiation tests   scanning   filter back-projection algorithm
