Abstract: After researching the 2-D image reconstruction algorithms, an improved 2-D iterative projection method is presented, so calculation is reduced, antinoise performance is enhanced, and more clear and accurate reconstructed images are obtained. Based on the algorithm above, the software of ICT image processing system is developed with VC++, which improves the quality of reconstructed images, provides experimental data with more convenient and systemic management, and realizes the automatic detection of disfigurements.
