  1. 143. Femtosecond X-ray Imaging using Free Electron Lasers
    Dr Anton Barty (Center for Free Electron Laser Science)

    Imaging theory
    Oral presentation
    The development of free electron lasers in the X-ray regime has opened up new frontiers in X-ray imaging. With X-ray pulses of only a few femtoseconds duration and sufficient peak power to produce high-quality diffraction patterns from a single pulse, recent experiments at the Linac Coherent Light Source (LCLS) have demonstrated structural determination from both isolated viruses and streams...

  2. 128. Equalization of Medipix2 imaging detector energy thresholds using measurement of polychromatic X-ray beam attenuation

    Imaging theory
    Oral presentation
    The single photon counting pixel detector Medipix2 is a powerful tool for energy resolved X-ray imaging. It allows discriminating energy of incoming X-rays by setting an energy threshold common to all pixels. As parameters of individual pixels vary, each pixel further contains a 3-bit digital-to-analogue converter (DAC) adjustment. Values of these DACs are traditionally determined by finding...

  3. 117. Phase contrast imaging of lightweight objects using microfocus X-ray source and high resolution CCD camera
    Mr Zaprazny Zdenko (Slovak Academy of Sciences)

    Imaging theory
    Oral presentation
    Modern laboratory X-ray imaging systems with microfocus source and CCD camera give us the possibility to move some of modern imaging techniques from synchrotrons to laboratories. Spatially coherent X-rays emited from microfocus source traverse a sample with phase shift. Beam deflection induced by the local change of refractive index may be expressed as dark-bright contrast on the edges in...
