For high resolution CT image reconstruction, algebraic reconstruction methods are widely used to get relatively good image quality. However, the slow speed has prohibited its routine use in clinical and industrial applications. Many GPU-based accelerated algebraic reconstruction methods have been presented for three-dimensional (3D) reconstruction in cone beam CT. But for the high resolution two-dimensional...
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 (RTV) for Cone-beam CT with latest GPU Tesla C1060. Unlike the former solutions, this method can visualize...
The circular cone-beam CT is one of the most widely adopted data-acquisition configurations in clinical and industrial applications, because it makes use of X-ray more effectively and shortens the scanning time. Among many algorithms for cone-beam circular scans, the FDK algorithm is the most widely used algorithm. It gives reasonably good results for small cone angle CT in case of no truncation in...
