    • Abstract
  • In some online control CT systems,people need to tackle the problems of median reconstruction results during the CT scanning. It requires a very high computing capacity to realize an online reconstruction and immediate volume rendering. This paper presents a complete Real-Time Visualization method for Cone-beam CT with latest GPU Tesla C1060. Unlike the former solutions,this method can visualize the intermediate results of the reconstruction procedure during scanning each projection. We can clearly see how the filtered projection data group forms a 3D volumetric reconstruction,and how broken projections and bunch of error pixels affect the final result. The final volume rendering result is obtained as soon as the scanning is completed. This method can also be a good alternative for 4D CT visualization.
