Computed Tomography (CT) has been an irreplaceable method of non-destructive testing in heavy industry and architectural design for a long time. Although, in recent years, a new CT technology with high resolution and extensive applicability for in-situ large-scale structure inspection of concrete has been applied in production. The complexity of the scanning environment and mechanical vibration during the in-situ press loading can result in artifacts on CT image. To solve this problem, a reconstruction algorithm based on system matrix was implemented to reduce of influence caused by track jitter and undefined scanning track. A simulation experiment was performed to verify the algorithm. The result shows the feasibility of the proposed reconstruction algorithm.
