  1. Individual and population averages for mean and intra-fraction standard deviation (Ia SD) for shallow breathing (SB) amplitude (ASB), deep inspiration breath hold (DIBH) amplitude (ADIBH) and instability (IDIBH). The number of DIBHs required for treatment is indicated by N, mean and standard deviations are displayed for DIBH (tDIBH) and treatment time (tT).
