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...
Report commissioning and initial clinical experience using automated breath hold (BH) delivery with Elekta Unity’s Comprehensive Motion Management (CMM).
Longitudinal deformable registration is crucial for accurate dose accumulation in magnetic resonance guided adaptive radiotherapy (MRgART). This is particularly difficult for pancreatic cancer, with both substantial inter-fraction spatial shifts and intensity...
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...
Therapy Physics
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...
To quantify longitudinal changes in Diffusion Weighted MRI (DWI) acquired during MR-LINAC adaptive radiotherapy for pancreatic cancer and correlate with clinical outcomes.
