Table 5 Delivery analysis of each treatment phase: number of monitor units (MUs), treatment time (minutes:seconds) - registered from the beginning of the first beam till the end of the last beam - and the percentage of the measurement points with γ < 1 - which compares Delta4 measurements and Pinnacle dose calculations
