| Abstract: | Long time required to obtain an image has been one of the major drawbacks associated with computerized tomography (CT ) technique. Therefore, researching new technique used in CT is one of the most important directions. According to the need and characteristic of 3D-CT image reconstruction, this paper puts forward a parallel processing system for fast 3D-CT image reconstruction by circular shifting float memory architecture. This is a structure that allows for linear increase in computation speed with increased number of processors. The schematic analysis for 3D-CT image reconstruction, parallel processing architecture and theoretical results are described. |
