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...

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...
