Hiroshi Mayahara

About

Dr. Hiroshi Mayahara is a leading expert in stereotactic body radiotherapy (SBRT), with a specialized focus on the CyberKnife robotic radiosurgery system. His research centers on optimizing real-time tumor motion tracking for moving targets in the lung and liver, addressing a critical challenge in precision radiation oncology. Dr. Mayahara’s major contributions include a landmark 2019 study (11 citations) that retrospectively assessed single fiducial marker tracking for liver tumors, revealing key uncertainties in the Synchrony system and establishing safer treatment margins. He further advanced the field by demonstrating how fiducial marker position directly influences internal target volume (ITV) in lung SBRT (2022, 5 citations), providing essential guidance for clinicians. His work also explores the impact of patient positioning—comparing supine versus prone setups for different lung tumor locations (2021, 2 citations)—to overcome the CyberKnife’s geometric limitations. With a career dedicated to refining motion management and treatment planning, Dr. Mayahara’s research has directly improved the accuracy and safety of SBRT, making him a respected voice in the fight against thoracic and hepatic malignancies.
