About

Takehiro Shiinoki is a leading figure in the advancement of precision radiotherapy, specializing in medical physics, robotic phantom systems, and patient-specific quality assurance (QA) for real-time tumor-tracking treatments. His major contributions center on the development of novel dynamic robotic moving phantoms that accurately reproduce patient three-dimensional tumor motion and anatomy, enabling rigorous QA for respiratory-gated stereotactic body radiotherapy. Notably, his 2020 work on a dynamic robotic phantom for patient-specific QA in real-time tumor-tracking radiotherapy has garnered 14 citations, underscoring its clinical relevance. Shiinoki further advanced the field by implementing a six degree-of-freedom (6DoF) high-precision robotic phantom on a commercial industrial manipulator, allowing for comprehensive dosimetric analysis of intrafraction translation and rotation during lung cancer treatments. His 2020 study analyzing the dosimetric impact of these motions during respiratory-gated SBRT, with 6 citations, highlights the critical need for rotational error correction. Additionally, his reference trajectory correction algorithm, published in 2018, enhances tracking accuracy for these robotic QA systems. Through these innovations, Shiinoki has significantly improved the safety and efficacy of real-time tumor-tracking radiotherapy, providing essential tools for clinical physicists and radiation oncologists.
