About one third of all deaths worldwide can be traced back to cardiovascular diseases, for which digital subtraction angiography (DSA) is an important diagnostic radiological procedure. An alternative to DSA is K-edge subtraction (KES) imaging, which can eliminate image artifacts caused by patient movement. As highly brilliant, monochromatic X-rays are desirable for this method, it has been limited to synchrotron facilities so far, restraining the feasibility in clinical routine. Compact synchrotron X-ray sources based on inverse Compton scattering, which have been evolving substantially over the past decade, provide X-rays with sufficient brilliance that meet spatial and financial requirements affordable in laboratory settings or for university hospitals. In this study, we demonstrate a first proof-of-principle KES imaging experiment using the Munich Compact Light Source (MuCLS), the first user-dedicated installation of a compact synchrotron X-ray source worldwide. We believe that KES at a compact synchrotron source can become an important tool in pre-clinical research.
