Cone-beam performance for different volume sizes. Performance scaling of cone-beam BP, FP and SIRT routines over a range of volume sizes. Presented is the time required, in seconds, to execute a single BP (top panel), single FP (bottom panel) and single SIRT iteration (middle panel). We increase the volume size from \(256^3\) to \(2048^3\). For a volume size of \(N^3\), the detector size is \(N^2\), and N projections are used. Missing data points are due to not enough total GPU memory
