The convolution backprojection (CBP) and Fourier inversion method (FIM) are popular tomographic image reconstruction techniques. However, the time required to reconstruct an image has been the major drawback associated with these techniques. We have designed a bus-based extended hypercube (BEH) that combines the positive features of both the bus based systems and the hypercube. We have executed the CBP and FIM algorithms on a hypercube, extended hypercube and on BEH. The reasons for high speedup of the BEH for image reconstruction tasks could be attributed to fast collective communication and collective computation algorithms of the BEH
