Evaluation of Intrafractional Anatomical Variations During Liver Magnetic Resonance-guided Adaptive Radiation Therapy Under Abdominal Compression Using Optical Flow Calculation
Optical flow analysis underestimated the SI motion range in the coronal plane compared with that in the sagittal plane during liver MRgART under AC. Tumor motion should be monitored in the sagittal plane, considering the sliding motion of the liver, with individualized margins according to tumor location.
