Percent dose measurements (TLD) for the IMRT field using static and dynamic IMRT deliveries. Measurements are normalized to 10 cm depth on the central axis. One standard deviation was estimated at 1.2% for the depth dose measurements and 1.7% for ratio values. Central‐axis and off‐axis measurement locations are shown in Fig. 3.

	off‐axis	41.0	58.0	67.4	41.8
	percent ratio	41.7	40.4	39.9	41.8
