"Investigating volumetric repainting to mitigate interplay effect on 4D" by Suresh Rana and Anatoly B. Rosenfeld
Purpose: The interplay effect between dynamic pencil proton beams and motion of the lung tumor presents a challenge in treating lung cancer patients in pencil beam scanning (PBS) proton therapy. The main purpose of the current study was to investigate the interplay effect on the volumetric repainting lung plans with beam delivery in alternating order (“down” and “up” directions), and explore the number of volumetric repaintings needed to achieve acceptable lung cancer PBS proton plan. Method: The current retrospective study included ten lung cancer patients. The total dose prescription...
