Phase-contrast imaging with Compact Light Source based on inverse Compton X-rays — •Simone Schleede1, Martin Bech1, Klaus Achterhold1, Guillaume Potdevin1, Ronald Ruth2,3, Jeff Rifkin3, Rod Loewen3, Marco Walter4, and Franz Pfeiffer1 — 1Department of Physics (E17) and Institute of Medical Engineering (IMETUM), Technische Universität München, Germany — 2Stanford Linear Accelerator Center, Menlo Park, USA — 3Lyncean Technologies Inc., Palo Alto, USA — 4microworks GmbH, Karlsruhe, Germany
The Compact Light Source, a laser driven small-size synchrotron developed by Lyncean Technologies Inc., produces x-rays at the intersection point of counter propagating laser and electron beam in the process of inverse compton scattering. The small size of the intersection point results in a highly coherent beam with a few milliradian angular divergence and three percent energy bandwidth. The intrinsic monochromaticity and coherence of the produced x-rays can be exploited in high-sensitivity differential phase contrast imaging with a grating-based interferometer. The Compact Light Source has the potential to yield images of quality previously only attained at large-scale synchrotron facilities, while being a small-size and low-cost x-ray source which allows it to be installed in hospitals for medical imaging. Here, we report on the first biomedical imaging results obtained from the Compact Light Source including mammography and computed tomography.
