About
Kazuhiko Hayashi is a leading medical physicist whose research focuses on advancing stereotactic ablative body radiotherapy (SABR) and small-field dosimetry, particularly using the CyberKnife robotic radiosurgery system. His major contributions include pioneering a novel SABR technique for metastatic lung tumors that delivers a central high dose within the gross tumor volume while maintaining steep dose gradients, potentially improving local control without increasing toxicity. This work, published in 2023, has already garnered 7 citations for its clinical significance. Hayashi is also recognized for his rigorous evaluation of calibration methods for the Exradin W2 plastic scintillation detector in CyberKnife small-field dosimetry (2022, 11 citations), addressing critical challenges in accurate dose measurement for nonstandard fields. His research directly impacts the precision and safety of stereotactic treatments, bridging the gap between advanced delivery technology and reliable dosimetric verification. With his work cited in both clinical and physics literature, Hayashi is establishing himself as a key figure in the optimization of robotic radiosurgery for thoracic malignancies and the metrology of small radiation fields.
