    • Abstract
  • This paper provides the improved iterative algorithms as commonly applied in Industrial Computerized Tomography (ICT).The symmetric mesh-iterative reconstruction technique (SM-IRT) is introduced based on the existing symmetric structure of projection lines so as to better solve the image reconstruction problems.This method proposes simplified computation of projection matrix and effectively adjusts the successive line iterative sequences.The experimental image reconstruction utilizing both simulated data and ICT experimental data is undertaken.The results show that the image reconstruction adopting the presented algorithms is much faster and takes on better precision than other conventional algorithms.
