About

Marie-Ange Janvier is a biomedical engineer and researcher whose work sits at the intersection of medical robotics, ultrasound imaging, and vascular diagnostics. Her research has focused primarily on the development and validation of robotic three-dimensional ultrasound imaging systems designed to detect and quantify peripheral arterial disease (PAD), particularly arterial stenoses in the lower limbs. Janvier's most significant contribution lies in advancing beyond the limitations of conventional 2D freehand ultrasound by engineering a robotic 3D-ultrasound platform capable of delivering precise, reproducible vascular assessments over extended arterial segments. Her most cited work, a 2007 performance evaluation of this system (58 citations), established a foundational benchmark for robotic medical imaging. Subsequent studies validated the system against mimicked and in vivo femoral artery models, demonstrating its clinical feasibility and geometric accuracy in reconstructing vessel morphology. Her in vivo feasibility study published in 2013 marked a meaningful translational milestone, bringing laboratory-validated technology closer to real-world clinical application. Collectively, her body of work addresses a genuine diagnostic gap — providing a low-cost, safe, and highly precise alternative for assessing atherosclerotic disease — making her research particularly valuable for clinicians and biomedical engineers working to improve vascular imaging standards.
