  1. 1. Small-Animal Imaging with Liquid-Metal-Jet X-Ray Sources

    Författare :Daniel Larsson; Hans Hertz; Anna Burvall; David Paterson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray; x-ray imaging; small animal; phase contrast; tomography; Fysik; Physics;

    Sammanfattning : Small-animal x-ray imaging is an important tool for medical research. The penetration power of x-rays makes it possible to investigate the 3D structure of small animals and other thick biological samples by computed tomography (CT). LÄS MER

  3. 2. Phase-Contrast X-Ray Carbon Dioxide Angiography

    Författare :Ulf Lundström; Hans Hertz; Anna Burvall; Ulrich Vogt; Franz Pfeiffer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Phase-contrast x-ray imaging is an emerging technology, which allows for imaging of smaller features than conventional absorption-based x-ray imaging, with lower radiation dose. Instead of the attenuation that is normally used in x-ray imaging, it utilizes the phase shift introduced by an object to the transmitted x-rays. LÄS MER

  4. 3. Magnetic resonance imaging techniques for evaluation of left ventricular function

    Författare :Ulrika Pahlm; Lund Klinisk fysiologi; []
    Nyckelord :;

    Sammanfattning : Hjärtinfarkt är en av de vanligaste anledningarna till för tidig död. Vid en hjärtinfarkt dör delar av hjärtmuskeln på grund av att den utsätts för mycket kraftig syrebrist när ett kranskärl täpps till. Även hjärtmuskelvävnad i infarktens närhet påverkas. Hjärtats vänsterkammare förser kroppen med syresatt blod. LÄS MER

  5. 4. Preclinical Molecular Imaging using Multi-Isotope Digital Autoradiography - Techniques and Applications

    Författare :Anders Örbom; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Autoradiography; Radioimmunotherapy; Antibodies; Molecular Imaging; Multi-Radionuclide Imaging; Silicon-strip detector;

    Sammanfattning : Molecular imaging, both in vivo and ex vivo, is playing an increasingly important role in preclinical medical research. When using radionuclide-labeled tracers, e.g. in the development of radiopharmaceuticals for diagnostic imaging or for radionuclide therapy, quantitative in vivo imaging can be performed using emission tomography.

  7. 5. Development of Flourescence-based Immunosensors for Continous Carbohydrate Monotoring : Applications for Maltose and Glucose

    Författare :Henrik Engström; Sten Ohlson; Per Ola Andersson; Christopher Lowe; Högskolan i Kalmar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carbohydrate; Diabetes; Immunosensor; ; Glucose; Maltose; Weak affinity chromatograhpy; Kolhydrater; Glukos; Maltose; Affinitetskromatografi; Diabetes; Biochemistry; Biokemi; Bioteknik; Biotechnology;

    Sammanfattning : Weak affinity interaction of monoclonal antibodies and carbohydrate antigens can be detected and quantified by alterations in the antibodies' intrinsic tryptophan fluorescence. These weak/transient binding events have been monitored by total internal reflection fluorescence (TlRF) by facilitating the change in intrinsic tryptophan fluorescence. LÄS MER
