Abstract
For the purpose of applying CT by X-band linac to NDE of bridges, NPPs and architectures, relative experiment and imaging reconstruction is studied. Three reconstruction algorithms of FBP, ART and SART are compared in consideration of partial projection situation because possible scanning is confined to smaller than 180° angle and a few translations during inspection. CT system with linacs under 4Mev for scanning will work on-site as Japanese law permitted. Moreover, 3D model can be built based on reconstructed images to evaluate load-bearing performance of bridges with VCAD system.
