From: Non-rigid registration of breast surfaces using the laplace and diffusion equations
TPS registration error for non-uniformly distributed fiducials. TPS registration error (averaged over 20 trials) for breast surfaces deformed by three simulations. Max and mean TRE (solid and dotted lines, respectively) were calculated for different numbers of non-uniformly distributed fiducials, where a high number of fiducials was placed in the region contacting the simulated compression bladder and a varying number elsewhere. When a high number of fiducials was placed in the contact region, increasing the number of total fiducials did not significantly decrease the TPS registration error.
