High resolution 3-dimensional tomography with X-rays at Singapore synchrotron light source

Over the past few years, results from the phase contrast imaging and tomography (PCIT) beamline at the Singapore Synchrotron Light Source (SSLS) have shown that high resolution (about 1 μm) 2-dimensional (2D) and 3-dimensional (3D) can be achieved in spite of the large emittance of the Helios 2 storage ring. Using white radiation the photon flux is high enough to perform real time radiology (100 ms per frame) at high lateral resolution as well as high-speed 2D imaging and 3D tomography. Refractive edge enhancement was also observed. PCIT is mostly used for materials and process characterization.
