Table 5.
Ideal dose-volume criteria for heart and corresponding achieved values (averages and standard deviations). Averages and standard deviations were calculated separately for left-sided and right-sided breasts for all plan options with data from applicable cases. V16Gy and V8Gy of heart for right-sided breast, which were all trivial for all plan options, are not listed.
