Enhanced contrast radiography with channel-cut crystals at the LNLS
2005
Review of Scientific Instruments
An analyzer-based x-ray phase contrast imaging ͑PCI͒ setup based on channel-cut crystals at the Laboratorio Nacional de Luz Sincrotron ͑LNLS-Brazilian Synchrotron͒ is presented. The contrast, visibility, signal-to-noise ratio and spatial resolution of the acquired images were characterized. The potential of PCI for enhancing details of different features with the same x-ray attenuation coefficient is exploited together with cross section simulations of the PCIs acquired at different angular
