3DVH - 3D Patient Dose and DVH Analysis

3DVH can use existing IMRT or rotational delivery measurements (e.g. MapCHECK™ or ArcCHECK™) to perform 3D patient dose and DVH QA, effectively eliminating dose-to-phantom guesswork. 3DVH avoids the uncertainty and overhead of a duplicate dose calculation engine and introduction of new errors. The 3D patient planned dose is perturbed using the errors measured in conventional QA.

Using conventional QA measurements, 3DVH predicts the impact on patient dose and DVH. 3DVH processes the data from a phantom-based geometry and translates to a heterogeneous patient dose-based geometry using a patent pending algorithm called “Planned Dose Perturbation” (PDP™).
