About
Kazuhiko Ogawa is a medical physicist whose research centers on robotic radiosurgery, real-time tumor tracking, and quality assurance in radiation therapy, with a particular focus on the CyberKnife Synchrony™ system. His most influential work addresses a critical challenge in radiotherapy: accurately targeting tumors that move with respiration. His 2018 study evaluating the Synchrony™ Respiratory Tracking System using plastic scintillators (31 citations) introduced a novel approach to temporal accuracy assessment beyond conventional film-based methods, while his 2019 follow-up (27 citations) investigated how respiratory phase shifts compromise tracking fidelity — findings with direct clinical implications for lung and liver cancer patients. Ogawa has also made meaningful contributions to prostate cancer radiosurgery, quantifying the dosimetric consequences of intra-fraction prostate motion during fiducial-based tracking (15 citations). His methodological work spans dose verification frameworks, small-field dosimetry calibration, and reference respiratory waveform modeling, collectively strengthening the precision and safety of robotic radiosurgery workflows. More recently, he has extended this expertise to stereotactic ablative body radiotherapy for metastatic lung tumors. Across his career, Ogawa's work has provided both the physics community and clinicians with rigorous, practical tools for improving treatment accuracy in motion-adaptive radiotherapy.
