About

Toshiharu Mitsuhashi is a leading researcher in interventional radiology, with a focus on advancing robotic systems for computed tomography (CT)-guided needle interventions. His primary research areas include the development and validation of robotic platforms for precise needle insertion, particularly for out-of-plane trajectories, which are challenging in manual procedures. Mitsuhashi’s major contributions center on the Zerobot, a robotic system developed at his institution, which he has rigorously tested in phantom and animal models. His seminal 2017 study, cited 53 times, demonstrated the feasibility of robotically driven CT-guided needle insertion, showing superior accuracy over manual methods in phantom experiments. Building on this, his 2019 work (35 citations) specifically evaluated out-of-plane angle accuracy, further establishing the system’s clinical potential. These studies have significantly impacted the field by providing quantitative evidence that robotic assistance can enhance precision in CT-guided biopsies and ablations, reducing procedural errors. Mitsuhashi’s work is notable for bridging engineering and clinical practice, offering a pathway to safer, more reliable interventions. His research continues to influence the design of next-generation interventional robots, making him a key figure in the evolution of image-guided therapy.
