In this work, the reconstruction time required for temporally constrained reconstruction of a large cardiac perfusion data set was reduced by utilizing 12 graphics processing units distributed across 6 different compute nodes. A speedup of over 30x was achieved compared to a 16 core CPU system resulting in a reconstruction time of only 48 seconds.
