About

Gerlig Widmann is a leading figure in the field of image-guided surgery and interventional radiology, with a primary focus on stereotactic and robotic systems for high-precision procedures. His research addresses the critical challenge of accuracy in complex anatomical environments, particularly in the cranial area and the liver. Widmann’s major contributions include pioneering work on respiratory motion control for stereotactic liver interventions, where he demonstrated the effectiveness of temporary endotracheal tube disconnections to minimize motion error—a technique essential for safe robotic ablation. His comparative phantom studies on frameless stereotactic and robot-assisted CT-based puncture have provided foundational data on accuracy across different imaging slice thicknesses, directly impacting clinical protocols. With over 130 citations across his most-cited works, his 2007 paper on image-guided surgery in the cranial area remains a key reference, highlighting the integration of robotics with optical navigation to enhance surgical outcomes. Widmann’s work bridges the gap between experimental tools and clinical necessity, earning him recognition as a pioneer in stereotactic and robotic ablation technologies.
