Fig. 2

Histograms of daily dosimetric outcome based on Breast PTV Eval and BODY contours. Red vertical lines represent dose-volume constraints as defined on Table 1 (dashed: treatment objectives, solid: variation acceptable). Abbreviations: Med = median; Std = Standard deviation. a Top row: dosimetric endpoints for the Breast PTV Eval contour. Bottom row: for BODY contour. Number of treatments that meet the dose-volume objectives laid out on Table 1 is represented as a fraction out of 126, in the following format ‘N/126 (M/126)’ where N = # meeting objectives and M = # within the variation acceptable. b Corresponding histograms of daily dosimetric outcome, represented as difference from what was originally planned for the treatment courses. Number of treatments that do not deviate significantly from planned (N) are represented in format ‘N/126’, where “significant deviation” means “minimum deviation that would cause a plan meeting all dosimetric endpoints to extend beyond variation acceptable
