Table III.

Beam-on time (seconds) and coefficient of variation (%) when blocking SURLAS electronics of the superficial planning target volume (PTV) for treatment plans where the long axis of the SURLAS is perpendicular to the longitudinal axis of the RANDO phantom.

	Complete blocking of SURLAS electronics	Directional blocking of SURLAS electronics
PTVD95% (Gy)	50.1	50.1
PTV coefficient of variation (%)	2.8	1.6
Beam-on time (seconds)	346	267

PTVD95%: Dose covering 95% of the PTV.

Coefficient of variation: standard deviation of the PTV dose distribution divided by the PTV average dose.
