  1. 11. Preclinical Molecular Imaging using Multi-Isotope Digital Autoradiography - Techniques and Applications

    Författare :Anders Örbom; Lunds universitet.; Lund University.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radioimmunotherapy; Autoradiography; 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.

  2. 12. Live Single Cell Imaging and Analysis Using Microfluidic Devices

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Mohammad Ali Khorshidi; KTH.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single cell analysis; time-lapse fluorescence imaging; automated image analysis; microwell; droplet microfluidics; NK cells; single cell tracking; migration behavior analysis; cell-cell interaction; optical microscopy; image analysis; image processing; microfluidics; immune cells; tracking; counting; morphology analysis;

    Sammanfattning : Today many cell biological techniques study large cell populations where an average estimate of individual cells’ behavior is observed. On the other hand, single cell analysis is required for studying functional heterogeneities between cells within populations. LÄS MER

  3. 13. Guidance and Visualization for Brain Tumor Surgery

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Filipe Miguel Maria Marreiros; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Image guidance and visualization play an important role in modern surgery to help surgeons perform their surgical procedures. Here, the focus is on neurosurgery applications, in particular brain tumor surgery where a craniotomy (opening of the skull) is performed to access directly the brain region to be treated. LÄS MER

  4. 14. Abdominal Aortic Aneurysm Molecular Imaging Studies of Pathophysiology

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Sammanfattning : The pathological process behind abdominal aortic aneurysm (AAA) formation is poorly understood and difficult to study. The aim of the thesis was to study the pathophysiology of AAA formation with positron emission tomography (PET) technology, a molecular imaging technique, allowing in vivo studies of pathophysiological changes.

    Sammanfattning : Early detection is vital to successfully treating breast cancer, and mammography screening is the most efficient and wide-spread method to reach this goal. Imaging low-contrast targets, while minimizing the radiation exposure to a large population is, however, a major challenge. LÄS MER
