Table 2.

Percent discrepancy from the nominal value of single fraction and cumulative D₉₉ for the CTV, when the per beam changes in probability of motion are ignored. Given is the mean, median, 95^th percentile, and maximum of all single fractions, both when the patient specific PDF was constructed using kV fluoroscopy measurements during dose delivery and using post-treatment CBCT localization.
