Investigate the Feasibility of Using CBCT to Assess the Dose Validation for Spot-Scanning Proton Arc (SPArc) Therapy for Advanced Staged Lung Cancer Treatment

Deep-learning CBCT-based synthetic CT could be used in dose validation not only for IMPT but also for SPArc even though SPArc plan has better dose conformity to the target. This finding paves the road map to the CBCT-based adaptation platform for SPArc adaptive therapy of lung cancer patient.
