About

Mark De Ridder is a leading figure in radiation oncology, whose research has fundamentally advanced the precision of cancer treatment. His work centers on stereotactic radiosurgery (SRS) and stereotactic ablative body radiotherapy (SBRT), with a particular focus on overcoming the critical challenge of tumor motion. De Ridder’s major contributions lie in the development and clinical validation of high-accuracy, real-time tumor tracking systems. His seminal 2011 papers on the geometric accuracy of a novel gimbals-based tracking system (164 citations) and the setup accuracy of the Novalis ExacTrac 6DOF system for frameless radiosurgery (132 citations) established new benchmarks for sub-millimeter precision. Further, his clinical evaluation of a robotic 6-degree-of-freedom treatment couch (130 citations) demonstrated how to safely and effectively eliminate patient positioning errors without invasive frames. More recently, his work on dynamic lung tumor tracking for SBRT (2015) addressed the hazardous risks of physical tumor miss in extracranial targets, showcasing a first-of-its-kind platform for high-precision ablative radiation. With over 435 citations across his most influential works, De Ridder’s innovations have directly shaped modern frameless radiosurgery and motion management, making treatments safer and more effective for patients worldwide.
