4D dose reconstruction for scanned proton therapy using liver 4DCT-MRI

4DCT-MRI can simulate many 4DCT data sets by combining patient CT with motion extracted from 4DMRI studies. 4DCT-MRI images have been generated using different motion extraction approaches and compared with 4DCT data of liver patients. This method extends the capabilities of motion modeling for accurate 4D dose calculations by accounting for realistic and variable motion patterns. 4DCT-MRI enables plan robustness studies to different motion conditions and 4D dose reconstruction of delivered plan for patient-specific QA.
