Abbreviations: ∑ the SD of all patients’ M, σ the root mean square of all patients’ SD, TDBA the differences in MPTV before and after correction, Before the correction, ∑total
2 = (∑initial inter-fraction)2 + (∑intra-fraction)2, σtota
2 = (σinitial inter-fraction)2 + (σintra-fraction)2; After the correction, ∑total
2 = (∑residual inter-fraction)2 + (∑intra-fraction)2, σtotal
2 = (σresidual inter-fraction)2 + (σintra-fraction)2. Other abbreviations as in Table 2.
