Intrafraction motion management is essential to reduce setup uncertainty and prevent dose delivery errors during radiotherapy, particularly for tumors influenced by respiratory motion near the diaphragm. Magnetic resonance guided radiotherapy enables real-tim...

Stereotactic Body Radiation Therapy (SBRT) of the lung can cause large deformations which make accurate dose accumulation for retreatment challenging. This study investigates the effect of different deformable image registration (DIR) methods on dose error.
