About
Rikiya Onimaru is a leading figure in pediatric radiation oncology, whose work centers on advancing proton therapy for central nervous system (CNS) tumors in children, adolescents, and young adults. His primary research focus is the development and clinical validation of intensity-modulated proton craniospinal irradiation (ipCSI), a technique designed to reduce the long-term toxicities of conventional radiotherapy. Onimaru’s major contribution is the pioneering of a novel ipCSI system that integrates gantry-mounted orthogonal X-ray imagers with a robotic six-degrees-of-freedom patient table, enabling precise, large-field treatment. His landmark 2019 study, with 10 citations, demonstrated the clinical feasibility and benefit of this approach in nine patients aged 7–19 with medulloblastoma and germ cell tumors, showing improved dose conformity and sparing of critical structures. This work has established a new standard for craniospinal irradiation, directly impacting the care of young cancer patients. Onimaru’s achievements highlight his commitment to translating engineering innovations into tangible clinical outcomes, making him a key figure in the effort to minimize treatment-related morbidity in pediatric neuro-oncology.
