Project Details


Rapid volumetric image reconstruction is of paramount importance to clinicians for prompt diagnosis and analysis of complex tissue alternations. However, due to a high demand on computation for either the analytical or iterative image reconstruction algorithms, it is almost impossible to meet the requirement of real-time reconstruction. In addition, the iterative reconstruction algorithms are able to produce higher quality CT images in comparison with the Filtered BackProjection (FBP) method. The major disadvantage of the iterative reconstruction is its slow reconstruction speed. On the other hand, with high computing capability and broad banding characteristic, multi-core processors provide a new possibility and hopeful start in both real-time Digital Signal Processing and Image Processing in recent years. This project aims to parallelize a variety of image reconstruction algorithms, including analytical and iterative methods, and implement them on an existing multi-core platform system, towards a real-time 3-D medical image reconstruction.
