Purpose: To automatically compare dose volume histograms (DVHs) against a set of predetermined goals and constraints to facilitate pre‐treatment plan review. Method and Materials: The internal scripting language of the treatment planning system (Pinnacle 3 , Philips Medical Systems, Milpitas CA) is used to prepare DVH data for evaluation against a set of constraints identified by ROI name. These settings can specify maximum percent volume by dose, maximum dose for a percent volume, or a maximum point dose. The results are displayed in a dialog box and can also be saved or printed for inclusion in the plan documentation. Results: This program functions as planned, and completes its execution quickly. The dosimetrist's workflow is affected only marginally. Conclusion: The extra information provided by this analysis has been valuable to the staff responsible for plan review.
