Comparison of point doses for plans and measurement (cGy)

Plan	Solid slab maximum dose (Diff)^a	Central axis maximum dose	Eyelid dose (Diff)
MC	196.1	47.3	197.7 ± 10
EBT2	197 (+ 0.5%)	44	201^d (+ 1.7%)
Pinnacle_CT#^b	196.7 (+ 0.3%)	46.9	159.6 ± 4.5 (– 19.3%)
Pinnacle_W ROI^c	202.8 (+ 3.4%)	47.0	161.7 ± 6.8 (– 18.2%)

^aDiff = percentage of difference relative to the MC results.

^bPinnacle_CT# = Pinnacle plan based on the modified CT images.

^cPinnacle_W ROI = Pinnacle plan based on the contouring and density override for the tungsten shield and steel knob.

^dThis eyelid dose is the maximum dose taken from EBT2.
