Figure 6.

The standard deviations, $\sigma (\Delta {\rho }_{\mathrm{i}})$, of the relative positional change of the 10 digitized points defining the right and left coil between SIM and 5WK scans are shown for each patient. These data give the coil position uncertainty in each direction LAT, AP, and SI. The average across all patients is shown in the insert.
