About
Hiroya Shiomi is a medical physicist whose research has profoundly shaped the field of image-guided robotic radiosurgery, with a particular focus on respiratory motion compensation and real-time tumor tracking systems. Working primarily with the CyberKnife platform, Shiomi has dedicated his career to solving one of radiotherapy's most persistent challenges: accurately targeting tumors that shift with a patient's breathing. His landmark 2004 paper, "Respiration Tracking in Radiosurgery," has amassed over 337 citations and remains a foundational reference for the field, establishing core methodologies for robotic compensation of respiratory motion. Shiomi's subsequent work has systematically refined these techniques, investigating phase shifts, prediction errors, and patient-specific factors that influence tracking accuracy. His contributions extend to prostate cancer treatment, examining dosimetric consequences of intra-fraction motion during hypofractionated radiosurgery, as well as to quality assurance innovations, including novel measurement frameworks for delivery verification. Through rigorous experimental and clinical investigations, Shiomi has helped transform robotic radiosurgery from a promising concept into a clinically reliable modality, providing the medical physics community with tools and insights essential for safe, precise treatment of tumors in challenging anatomical sites.
