About

Franz Wegner is a pioneering researcher at the forefront of interventional magnetic particle imaging (MPI), a cutting-edge modality on the cusp of clinical translation. His work centers on the navigation and visualization of medical devices within the cardiovascular system, with a specific focus on revolutionizing the treatment of life-threatening conditions like cerebral aneurysms. Wegner’s most impactful contribution is the development of a helically shaped magnetic micro-robot that can be steered untethered through magnetic fields, offering a novel, minimally invasive alternative to traditional catheter-guided coiling or neurosurgical clipping. This landmark 2021 study, which has garnered 77 citations, demonstrates the robot’s navigation through a cerebral aneurysm phantom, showcasing its potential for targeted therapy. Further advancing the field, his 2024 work tackles a critical challenge: tracking bare-metal stents, which inherently lack MPI signal. By developing methods to visualize these devices, Wegner is paving the way for intraprocedural imaging guidance during stent placement, a key step toward making MPI a clinical reality for cardiovascular interventions. His research elegantly bridges device engineering and advanced imaging, promising safer, more precise procedures.
