Phase-contrast X-ray

Phase-contrast X-ray imaging for clinical use: From large synchrotrons to table-top

Imaging the vascular tree and tumor boundaries with a resolution better than 100 microns will greatly enhance the diagnostic value of cardiovascular and tumor imaging. The can be achieved by exploiting the phase change of an incoming coherent X-ray as a result of interaction with the sample. It requires a brilliant coherent source such as available in large synchrotron facilities as the ESRF. Bringing this technology to a hospital environment for patient imaging is a major challenge. We are developing quantitative models to design optimal scanning strategies; designing novel algorithms to disentangle attenuation and phase contributions; and developing dedicated image reconstruction techniques.
