Table 2.
The mean of the standard deviations of the tumor centroid position over 26 thoracic radiotherapy patients (52 fractions) and all the bins in each spatial direction for different scenarios of parameters of the respiratory trace used for sorting. The maximum differences for all the fractions and all the bins are also shown for each spatial direction.
