  1. 1. Laboratory X-Ray Phase-Contrast Imaging : Methods and Comparisons

    Författare :Tunhe Zhou; Anna Burvall; Hans M. Hertz; Tim Salditt; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray imaging; Phase-contrast; Liquid-metal-jet source; Propagation-based imaging; Grating-based imaging; Speckle-based imaging; Fysik; Physics;

    Sammanfattning : X-ray phase-contrast imaging has seen rapid development in recent decades due to its superior performance in imaging low-absorption objects, compared to traditional attenuation x-ray imaging. Having higher demand on coherence, x-ray phase-contrast imaging is performed mostly at synchrotrons. LÄS MER

    Sammanfattning : Chronic pain affects 20 % of the global population, causes suffering, is difficult to treat, and constitutes a large economic burden for society. So far, the characterization of molecular mechanisms of chronic pain-like behaviors in animal models has not translated into effective treatments. LÄS MER

  4. 3. X-ray Phase Contrast Tomography : Setup and Scintillator Development

    Författare :Hanna Dierks; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; x-rays; x-ray imaging; x-ray microscopy; X-ray detectors; perovskites; laboratory setups; phase contrast; μCT; scintillator; Phase contrast PC ; Tomography x-ray computed ;

    Sammanfattning : X-ray microscopy and micro-tomography (μCT) are valuable non-destructive examination methods in many disciplines such as bio-medical research, archaeometry, material science and paleontology. Besides being implemented at synchrotrons radiation sources, laboratory setups using an X-ray tube and high-resolution scintillation detector routinely provide information on the micrometre scale.
