About

Irving Kaplan is a radiation oncologist whose research focuses on advancing stereotactic body radiotherapy (SBRT) for abdominal and thoracic tumors, with particular emphasis on managing organ motion during treatment. His most influential work, "Organ Deformation and Dose Coverage in Robotic Respiratory-Tracking Radiotherapy" (2008, 51 citations), addresses a critical challenge in precision radiotherapy: how respiratory-induced organ deformation affects dose delivery accuracy. By quantifying the interplay between tumor motion and organ deformation, Kaplan’s study provided foundational insights for optimizing robotic tracking systems, directly improving treatment planning for mobile tumors. His earlier work, "Fractionated Radiosurgery for Pancreas Cancer" (2007, 6 citations), explored the feasibility of delivering high-dose radiation in multiple fractions to pancreatic tumors—a notoriously difficult site due to adjacent radiosensitive organs. Though less cited, this study contributed to the early clinical evidence supporting SBRT for pancreatic cancer, a field that has since expanded significantly. Kaplan’s research bridges the gap between engineering precision and clinical oncology, helping to make non-invasive, high-dose radiation safer and more effective for challenging tumor locations.
