FIG. 1.

Absolute dose planes at 10 cm depth, 100 cm source-detector-distance (SDD) shown for (a) measured and (b) calculated dose. (c) 3%G/3 mm gamma failing points. (d) Dose profiles, dots represent calibrated diode measurements and solid lines the interpolated TPS profiles and (e) with measured profile (dotted) up-sampled using a commercial method (Refs. 12 and 13, and 34). (f) Patient sagittal planar dose from TPS and (g) with 3DVH-esimated error showing lower estimated patient dose as dose difference, and (h) as shifts in DVH curves for two target volumes.
