Fig. 4From: Can knowledge-based DVH predictions be used for automated, individualized quality assurance of radiotherapy treatment plans?The mid-prediction dose-volume histogram (DVH) line (dashed) running through the middle of the DVH prediction range (shaded region). This was used as a surrogate for the prediction DVH in this study and determined using an in-house developed program coded in Lazarus (http://www.lazarus.freepascal.org/)Back to article page
