  2. 21. Improving Assessments of Hemodynamics and Vascular Disease

    Author : Magnus Ziegler; Petter Dyverfeldt; Tino Ebbers; Jonas Lantz; Ebo de Muinck; Carljohan Carlhäll; Alex J. Barker; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Blood vessels are more than simple pipes, passively enabling blood to pass through them. Their form and function are dynamic, changing with both aging and disease. This process involves a feedback loop wherein changes to the shape of a blood vessel affect the hemodynamics, causing yet more structural adaptation. READ MORE

  4. 22. Geological Structure and Time-Lapse Studies of CO2 Injection at the Ketzin Pilot Site, Germany

    Author : Alexandra Ivanova; Christopher Juhlin; Milovan Urosevic; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 3D seismic time-lapse surveys (“4D seismics”) are an essential tool for large scale reservoir characterization. The target reservoir of the Ketzin pilot project for CO2 storage is a saline aquifer of the heterogeneous Stuttgart Formation (Upper Triassic) in the Northeast German Basin. READ MORE

  5. 23. Adaptive Multidimensional Filtering

    Author : Leif Haglund; Gösta Granlund; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis contains a presentation and an analysis of adaptive filtering strategies for multidimensional data. The size, shape and orientation of the flter are signal controlled and thus adapted locally to each neighbourhood according to a predefined model. READ MORE

  6. 24. Evaluation of Automatic Quantification Programs for Myocardial Perfusion SPECT using Monte Carlo Simulations

    Author : Henrik Hussein El Ali; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; medicinsk instrumentering; Nuclear physics; Kärnfysik; radiologi; Klinisk fysiologi; medical instrumentation; Severity; Monte Carlo; Clinical physics; radiology; tomography; Myocardial perfusion; Extent;

    Abstract : Coronary artery disease (CAD) is a condition in which the blood supply to the myocardium is partially or completely blocked due to plaque build-up in the artery wall. Myocardial SPECT imaging is a commonly used technique to assess the blood flow to the myocardium and the function of the heart. READ MORE

  7. 25. The role of monocytes in chronic inflammatory diseases

    Author : Sofia Björnfot Holmström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Monocytes and monocyte-derived cells are important players in the orchestration of inflammatory reactions in blood and peripheral tissues. However, little is known about the monocyte fate upon entry into human tissues, and current concepts are mainly based on animal models, with the addition of observational studies in humans that often do not allow determining causality.
