  3. 7. Phase-Contrast X-Ray Imaging of Complex Objects

    Författare :Ilian Häggmark; Hans Hertz; Anna Burvall; Henning Friis Poulsen; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysik; Physics; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : X-ray imaging is a group of techniques using electromagnetic radiation of high energy. The ability to quickly visualize internal structures in thick opaque objects has made it an indispensable tool in research, medicine, and industry. LÄS MER

  4. 8. The Human Vestibular Aqueduct, Endolymphatic Duct and Sac : A Morphological Study Using Micro-CT, Super Resolution Immunohistochemistry and Synchrotron Phase Contrast Imaging

    Författare :Charlotta Kämpfe Nordström; Helge Rask-Andersen; Göran Laurell; Claes Möller; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endolymphatic sac; endolymphatic duct; vestibular aqueduct; Meniere s disease; LVAS; micro-CT; synchrotron phase contrast imaging; Medicinsk vetenskap; Medical Science;

    Sammanfattning : The inner ear lies sheltered in the temporal bone and consists of basically three parts: the cochlea (the hearing organ), the vestibular (the balance organ), and the endolymphatic duct (ED) and endolymphatic sac (ES). The ES and ED are located in a bony canal, the vestibular aqueduct (VA), located on the medial side of the vestibule. LÄS MER

  5. 9. Accuracy and reproducibility in phase contrast magnetic resonance imaging

    Författare :Per Thunberg; Freddy Ståhlberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Magnetic resonance imaging (MRI) is an imaging modality which provides good conditions for studies of flow and motion in the cardiovascular system. When using the phase contrast imaging technique, it is possible to perform velocity measurements in moving tissues and in blood. LÄS MER

  7. 10. 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
