About

Gregor Laimer is an interventional radiology researcher whose work centers on advancing image-guided needle placement through robotic and optical tracking technologies. His research addresses a critical clinical challenge: improving the precision of minimally invasive percutaneous procedures such as biopsies and ablations, where millimeter-level accuracy can significantly affect patient outcomes. Laimer's most influential contributions include systematic phantom and ex vivo evaluations of robotic aiming and guidance systems. His 2022 comparative study of robotic versus patient-mounted CT-guided needle placement devices (15 citations) established important benchmarks for assessing these emerging technologies against conventional freehand techniques. Complementing this, his investigation of optically tracked hybrid robotic systems (11 citations) demonstrated the feasibility of integrating optical navigation with CT data for stereotactic punctures across varying slice thicknesses. His 2024 ex vivo study involving 240 needle punctures with the Micromate robotic platform further validated real-world clinical applicability, while his exploration of 2D fluoroscopic robot-assisted guidance expanded the technology's potential to C-arm-based settings. Collectively accumulating over 35 citations, Laimer's body of work provides a rigorous technical foundation for the clinical adoption of semi-automated robotic guidance in interventional radiology, making his research particularly valuable for clinicians and engineers developing next-generation procedural tools.
