Tatsuhiro Sera

About

Tatsuhiro Sera is a leading researcher in medical physics, specializing in advanced radiotherapy techniques for cancer treatment. His work centers on real-time tumor tracking, respiratory-gated radiotherapy, and patient-specific quality assurance (QA), with a particular focus on lung cancer. Sera’s major contributions include the development of a novel six degrees-of-freedom (6DoF) robotic moving phantom system that can accurately reproduce patient three-dimensional tumor motion and anatomy. This innovation enables precise dosimetric evaluation of intrafraction translation and rotation during stereotactic body radiotherapy (SBRT) with real-time tumor monitoring. His 2020 paper on this system, which has garnered 14 citations, demonstrates its critical role in patient-specific QA for respiratory-gated treatments using SyncTraX. Another highly cited work (6 citations) analyzes the dosimetric impact of intrafraction motion during lung SBRT, highlighting the importance of accounting for rotational errors. Sera’s research directly enhances treatment accuracy and safety, with his phantom system being a notable achievement that bridges engineering and clinical oncology. His work is essential for physicists and clinicians aiming to improve real-time adaptive radiotherapy.
