Dose-Guided Radiotherapy: Potential Benefit of Online Dose Recalculation for Stereotactic Lung Irradiation in Patients With Non-Small-Cell Lung Cancer

Dose-guided radiotherapy can be used to determine the actual dose in OARs when the target has moved with respect to the OARs. When the workflow is optimized for speed, it can be used to prevent unnecessary position corrections. Estimating the dose by assuming an invariant dose instead of recalculation of the dose gives clinically relevant errors.
