In this project, we have built a phase contrast X-ray tomograph based on a microfocus Cu source. Traditional X-ray imaging is based on absorption contrast, which has poor contrast for small and weakly absorbing samples. Much better contrast can be achieved using phase contrast. The system is based on a microfocus X-ray source with a Cu target, a high-resolution detector and a high-precision sample stage. It's capable of X-ray absorption contrast and phase contrast imaging at a spatial resolution of about 1 micrometer in 2D and 3D. The image above shows part of a blueberry seed. We have recently published our first results: [Dierks 2020]
