Review of Parallel Computing Techniques for Computed Tomography Image Reconstruction

Jun Ni, Xiang Li, Tao He, Ge Wang
2006 Current Medical Imaging Reviews  
This paper focuses on the speedup the computation using parallel computing. The first generation of parallel computing systems was based on a centralized parallel configuration.  ...  For a decent, a cone-beam reconstruction usually takes hours on a regular PC, since most of algorithms take more than 60 iterations even longer.  ...  (Fig. 6 ) Most of these studied have targeted EM and OS-EM algorithms for PET and SPECT. In [56] parallel OS-SART was implemented on a Linux cluster for X-ray CT.  ...
