About
Masahiro Hiraoka is a leading figure in radiation oncology, renowned for his pioneering work in frameless stereotactic radiosurgery and advanced dosimetric verification. His research centers on enhancing the geometric precision and safety of radiotherapy, particularly through the integration of robotic couch systems and three-dimensional motion compensation. Hiraoka’s seminal 2009 study on the geometric accuracy of frameless stereotactic radiosurgery using a 6D robotic couch system, cited over 119 times, established critical benchmarks for correcting patient positioning uncertainties, directly improving treatment outcomes for intracranial tumors. He also developed a novel three-dimensionally movable phantom system (2008), enabling real-time experimental verification of dose distributions during dynamic radiotherapy—a tool that has become essential for quality assurance in complex treatments. Beyond these contributions, Hiraoka has advanced the clinical translation of motion management technologies, ensuring that high-precision radiation delivery is both accurate and reproducible. His work has profoundly influenced stereotactic radiosurgery protocols worldwide, and his innovations continue to guide researchers and clinicians in minimizing treatment margins while maximizing tumor control.
