About

Hanne Sorger is a researcher whose work lies at the critical intersection of medical imaging and computer-assisted intervention, with a primary focus on improving the accuracy of navigated bronchoscopy. Her key research area addresses the fundamental challenge of intraoperative registration—specifically, how to align preoperative CT scans with the dynamic, shifting anatomy of a patient’s lungs during a procedure. Sorger’s major contribution, detailed in her highly cited 2017 paper “Intraoperative localized constrained registration in navigated bronchoscopy” (17 citations), is the development of a localized, constrained registration method that compensates for lung tissue deformation occurring between CT acquisition and surgery. This work directly tackles the problem of navigation accuracy, which is a major hurdle in electromagnetic navigated bronchoscopy. By proposing a technique that refines the initial rigid registration only where needed, Sorger’s research has helped pave the way for more reliable, real-time guidance during minimally invasive lung procedures. Her contributions are particularly notable for their potential to improve diagnostic and therapeutic outcomes in pulmonary medicine, making her a key figure in advancing the precision of image-guided interventions.
