Patient Specific Dosimetry Phantoms Using Multichannel LDDMM of the Whole Body
Figure 4
Time spent on computations, per image voxel per gradient descent iteration, for the four patients examined, plotted on a log-log axis. (a) Total time, (b) time in semi-Lagrangian advection, and (c) time in image interpolation. Note that in (a) small takes the longest, followed by med-small, med-large, and large. In (b) (for all processors) and (c) (from 1 to 8 processors), the order of the middle two is reversed.
