Table 1.

Daily target motion ranges (peak-to-peak) are shown for LR, AP, and SI directions for three motion mitigation scenarios. Values shown are mean [minimum – maximum] given in cm.

(cm)	LR	AP	SI
No motion mitigation	0.53 [0.18 – 1.24]	0.73 [0.35 – 1.82]	1.39 [0.47 – 3.55]
Abdominal compression	0.52 [0.13 – 1.37]	0.53† [0.19 – 1.31]	0.85† [0.16 – 1.71]
Respiratory gating	0.32‡ [0.12 – 1.24]	0.39‡ [0.15 – 1.16]	0.55‡ [0.15 – 0.84]

^†significantly lower (p<0.01) than no motion mitigation

^‡significantly lower (p<0.01) than both no motion mitigation and abdominal compression
