    • Abstract
  • Several preprocessing filters for CT reconstruction were analyzed and designed. By comparing and analyzing the quality of images reconstructed with different classical filters, several preprocessing filters are designed through improving filter function and combining with window function. The reconstruction experiments based on actual projection data indicate that these filters are effective in improving image qualities and can be used in actual CT reconstruction.
