About

Yuki Yuasa is a leading researcher in medical physics, specializing in advanced radiotherapy techniques for cancer treatment. Their work focuses on real-time tumor tracking, respiratory-gated radiotherapy, and patient-specific quality assurance (QA). Yuasa’s major contributions include the development of a novel dynamic robotic moving phantom system that reproduces patient three-dimensional tumor motion and anatomy, enabling precise QA for real-time tumor-tracking radiotherapy. This innovation, detailed in their 2020 paper with 14 citations, directly improves treatment accuracy for lung cancer patients. Additionally, Yuasa pioneered a six degrees-of-freedom (6DoF) robotic moving phantom to analyze the dosimetric impact of intrafraction translation and rotation during respiratory-gated stereotactic body radiotherapy, a study with 6 citations that addresses critical challenges in tumor monitoring. Their work has significantly enhanced the safety and efficacy of stereotactic body radiotherapy, reducing risks from tumor motion during treatment. Yuasa’s achievements underscore their impact on clinical radiotherapy, offering tools that bridge the gap between simulation and real-time delivery, and their research continues to influence patient-specific QA protocols worldwide.
