Summary results of accuracy tests of the Intra‐fraction Motion Management system (IFMM), registration algorithm, and delivery‐after‐shift to a film. The results for IFMM and registration (3D stage method) and the shot measurements are averaged over small (2 mm in each of x, y, and z direction) and large (5 mm in x and y directions, 20 mm in z direction, and 1 degree rotation along y) shift test scenarios. The difference is calculated as measured value minus expected value

Test		Average difference ± SD (mm)	[Range] (mm)
IFMM accuracy	(3D stage method)	0.00 ± 0.12	[−0.27, 0.23]
	(Transformation matrix method)	0.08 ± 0.08	[−0.07, 0.15]
Registration accuracy	(3D stage method)	0.03 ± 0.06	[−0.06, 0.23]
	(Transformation matrix method)	−0.01 ± 0.13	[−0.48, 0.21]
Delivery‐after‐shift accuracy		0.24 ± 0.09	[0.08, 0.42]
