About
Keisuke Otani is a leading researcher in the field of stereotactic body radiotherapy (SBRT) and advanced motion management for cancer treatment. His work centers on the critical challenge of tracking moving tumors—particularly in the liver and lungs—during real-time radiation delivery. Otani’s major contributions include pioneering studies on the CyberKnife Synchrony™ Respiratory Tracking System, where he quantified how respiratory phase shifts degrade motion-tracking accuracy, directly informing clinical protocols to reduce treatment errors. His research on correlation model errors (CME) and marker-tumor correlation errors (MTCE) during marker-based real-time tracking has been instrumental in understanding how both intrafraction and interfraction uncertainties impact dose coverage in liver SBRT. With his most cited paper garnering 27 citations, Otani’s work provides essential data for improving the precision of robotic radiosurgery. His findings help clinicians optimize the correlation between external surrogate markers and internal tumor motion, ultimately enhancing the safety and efficacy of SBRT for moving targets. Otani’s research is vital for any physicist or clinician seeking to minimize geometric errors in real-time tumor tracking.
