3D filtered backprojection for curved detector axial cone-beam data on a playstation® 3

Increasingly large CT data sets in combination with more sophisticated reconstruction algorithms and data corrections place an expanding burden on computing platforms. Furthermore, traditional processors are increasingly unable to deliver the required performance for processing these CT data sets. Emerging computing platforms such as powerful graphics processing units (GPUs) and the cell broadband engine (CBE) show promise for handling this increased computational burden. In this paper, we report the results of implementing a 3D filtered backprojection algorithm for curved detector axial cone-beam CT data on the CBE. The development platform for this work is a Sony playstationreg 3, which includes a CBE.
