A percutaneous transluminal angioplasty (PTA) is a procedure to widen stenotic blood vessels in medical conditions such as coronary heart disease or peripheral artery disease. With the assistance of fluoroscopic guidance and radiopaque contrast agents, guidewires and balloon catheters are used to treat vascular stenoses. Magnetic Particle Imaging (MPI) is a very fast and sensitive tomographic imaging modality with the potential of real-time radiation-free 3D imaging. In this work the feasibility of performing a MPI-guided PTA in artificial stenoses with a traveling wave MPI scanner is demonstrated.
