Dose accumulation using deformable image registration (DIR) enables a more accurate evaluation of delivered dose in adaptive radiotherapy, allowing evaluation of discrepancies between planned and delivered treatments. However, different DIR algorithms produce...
To evaluate whether two intrafraction CBCT-based motion corrections are sufficient and necessary to ensure accurate target coverage in online adaptive stereotactic body radiotherapy (SBRT) of prostate cancer.
Quantify dosimetric differences between original online adaptive plans (adapt-to-position [ATP] or adapt-to-shape [ATS]) and baseline shift (BLS)–corrected plans for prostate MRgRT on 1.5 Tesla MR-Linac. BLS is a fast, during treatment, replan applying virtua...
Simulation-free (SimF) workflows for MR-guided radiotherapy demonstrate potential to streamline treatment initiation by eliminating dedicated simulation scans. We evaluated the feasibility of implementing an SimF approach for single fraction liver SBRT on the...
