  6. 4. Laboratory x-ray fluorescence tomography

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Jakob C. Larsson; Hans Hertz; Anna Burvall; Ulrich Vogt; Norbert Pelc; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-ray; fluorescence; x-ray fluorescence; nanoparticle; xrf; xfct; tomography; Physics; Fysik;

    Abstract : X-ray fluorescence (XRF) tomography is an emerging bio-imaging modality with potential for high-resolution molecular imaging in 3D. In this technique the fluorescence signal from targeted nanoparticles (NPs) is measured, providing information about the spatial distribution and concentration of the NPs inside the object.

  7. 5. Phase-Contrast and High-Resolution Optics for X-Ray Microscopy

    University dissertation from Stockholm : KTH

    Author : Olof von Hofsten; Ulrich Vogt; Ian McNulty; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microscopy; X-ray optics; X-ray microscopy; Soft X-ray physics; NATURAL SCIENCES Physics Other physics Optics; NATURVETENSKAP Fysik Övrig fysik Optik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : X-ray microscopy is a well-established technique for nanoscale imaging. Zone plates are used as microscope objectives and provide high resolution, approaching 10 nm, currently limited by fabrication issues. This Thesis presents zone plate optics that achieve either high resolution or phase contrast in x-ray microscopy. READ MORE
