Masao Nakayama

About

Masao Nakayama is a leading figure in the advancement of stereotactic body radiotherapy (SBRT), with a particular focus on the precision and safety of robotic radiation delivery systems like the CyberKnife. His primary research addresses the critical challenge of managing respiratory motion during treatment, a key factor in effective tumor targeting. Nakayama’s most impactful work, a 2019 study with 11 citations, provides a rigorous retrospective assessment of single fiducial marker tracking for liver tumors, quantifying uncertainties in the CyberKnife Synchrony system. He further refined this field by investigating how fiducial marker placement influences target volume definition in lung SBRT (2022, 5 citations), offering vital guidance for treatment planning. Nakayama has also explored practical clinical considerations, such as the impact of patient positioning—comparing supine and prone setups for different lung tumor locations (2021, 2 citations). Through these contributions, he has helped establish more robust motion management protocols, directly improving the accuracy and safety of robotic SBRT for thoracic and abdominal cancers, making him a respected voice in modern radiation oncology.
