  1. 6. Virtual histology by laboratory x-ray phase-contrast tomography

    Författare :Jenny Romell; Hans Hertz; Anna Burvall; Julia Herzen; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Detailed imaging of biological samples is central to different fields of research, as well as for clinical pathology. Classical histology, using light- orelectron microscopy, can generate high-resolution images but is destructive and only gives two-dimensional information. LÄS MER

  3. 7. Phase-Contrast and Spectroscopic X-ray Imaging for Paperboard Quality Assurance

    Författare :Salim Reza; Christer Fröjdh; Börje Norlin; Jan Thim; Anna Burvall; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The end-use performance of a paperboard depends on its quality.The major properties of a good quality paperboard include consistencyin the expected ratio between the thickness of the core andthe coating layers, and the uniformity in the coating layer. LÄS MER

  4. 8. Applications of Laser-Plasma Acceleration

    Författare :Kristoffer Svendsen; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; laser wakefield acceleration; betatron radiation; X-rays; X-ray imaging; phase-contrast imaging; VHEE; radiotherapy; radiography; fuel injector; tomography; beam focusing; atomizing sprays; nanowires; liquid mass; target normal sheath acceleration; applications; charged particles;

    Sammanfattning : This thesis is dedicated to the investigation of laser-plasma particle acceleration concepts. Some of the work was focused on improving electron and proton acceleration for future applications, in terms of maximizing the particle energy and minimizing the divergence of the X-ray beams.

  5. 9. High resolution laboratory x-ray tomography for biomedical research : From design to application

    Författare :Till Dreier; Lund Medicinsk strålningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; x-ray; computed tomography; micro-CT; nano-CT; phase contrast; biomedical; super-resolution; material decomposition;

    Sammanfattning : Laboratory x-ray micro- and nano-tomography are emerging techniques in biomedical research. Through the use of phase-contrast, sufficient contrast can be achieved in soft tissue to support medical studies. LÄS MER

  7. 10. The Human Cochlea and Cochlear Implantation : Morphological Characteristics and Clinical Correlations

    Författare :Nadine Schart-Morén; Helge Rask-Andersen; Elina Mäki-Torkko; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cochlear implantation; micro-CT; synchrotron; facial nerve stimulation; hearing preservation; round window;

    Sammanfattning : The most common sensory deficit in the world is sensorineural hearing loss. Cochlear implantation (CI) can majorly contribute to restore hearing, not only in patients with severe to profound hearing loss, but also in hearing-impaired patients with residual low-frequency hearing.
