A Method to Estimate Accumulated Dose Uncertainties Induced by Deformable Image Registration Discrepancies for Adaptive Proton Therapy
(2020)Purpose: We propose a model for estimating dosimetric uncertainties as a consequence of discrepancies in the Deformable Image Registration (DIR) process when accumulating dose for adaptive Pencil Beam Scanned (PBS) proton therapy. Methods: Three components are considered: (i) deformable vector fields (DVFs) derived from different DIR algorithms; (ii) a patient specific linear regression model of DVF uncertainty, and (iii) dose gradients ...Conference Poster
