About

Yoshihisa Masaoka is a leading figure in interventional radiology and robotic-assisted medical procedures, with a primary focus on advancing the precision and safety of CT-guided needle insertions. His most influential work, "Robotically Driven CT-guided Needle Insertion: Preliminary Results in Phantom and Animal Experiments" (2017, 53 citations), demonstrates his pivotal role in bridging robotics and clinical imaging. In this study, Masaoka and his team evaluated the accuracy of a remote-controlled robotic system for CT-guided needle placement, comparing robotic and manual insertions in both phantom and animal models. The results showed that robotic guidance significantly improved targeting precision while reducing radiation exposure to operators, a critical advancement for minimally invasive biopsies and ablations. This work has laid the groundwork for integrating automation into interventional radiology, enhancing reproducibility and patient outcomes. Masaoka’s contributions are particularly notable for their translational impact, moving from bench to bedside by validating robotic systems in realistic preclinical settings. His research continues to inspire innovations in image-guided therapy, making him a key contributor to the evolution of precision medicine in interventional oncology and diagnostic radiology.
