Figure 3 Boxplot (as described in Figure 1) of radial treatment errors for 51 fiducials
implanted in different liver segment locations for 38 patients in 206 treatment fractions,
with number of fractions indicated in brackets under the box. For any fraction with
fiducials implanted in two or three liver segments, the Synchrony errors for each
fraction are weighted by the reciprocal of the number of implanted fiducials used during
the treatment.
