  2. 1. Advancements of 2D speckle tracking of arterial wall movements

    Author : John Albinsson; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultraljud; block-matching; vävnadsrörelser; longitudinal movement;

    Abstract : Cardiovascular diseases are the leading cause of death worldwide. In order to improve the diagnostics and facilitate early interventions of cardiovascular diseases, knowledge about the physiology of the vascular system in both healthy subjects and in subjects with vascular disease is needed.

  4. 2. The effect of pressure afterload due to aortic coarctation on left ventricular function in children

    Author : Haki Jashari; Michael Henein; Annika Rydberg; Katarina Hanséus; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coarctation of the aorta; congenital aortic stenosis; left ventricle; myocardial deformation imaging; speckle tracking echocardiography; longitudinal strain; aorto-septal angle; children; kardiologi; Cardiology;

    Abstract : Background:Coarctation of the aorta (CoA) is a congenital heart disease which represents a narrowing of the proximal descending aorta, hence increasing pressure afterload to the left ventricle (LV). Conventional treatment of native CoA is surgical repair, however potential recurrence or other related complications e.g. READ MORE

  5. 3. Not all those who wander are lost : A study of cancer cells by digital holographic imaging, fluorescence and a combination thereof

    Author : Sofia Kamlund; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Digital holography; longitudinal tracking; breast cancer stem cells; salinomycin; EMT; Digital Holography; longitudinal tracking of individual cells; breast cancer cells; Breast cancer; Salinomycin; cancer stem cells; Fluorescence microscopy; EMT;

    Abstract : Cells are commonly used in research to evaluate toxicity and efficiency of drugs. However, to further increase the usefulness of cells as well as the understandings of effects of different interventions, new methods must constantly be developed and refined. READ MORE

  6. 4. Tracking and predicting cognitive development using magnetic resonance imaging

    Author : Henrik Ullman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Neuroimaging of the developing brain has helped describing and quantifying many of the biological processes underlying cognitive development. The protracted development of higher order cognitive functions has allowed detailed description of their neural correlates. READ MORE

  7. 5. On the Use of Ultrasound Phase Data for Arterial Characterization

    Author : Tobias Erlöv; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atherosclerosis; Ultrasound; Carotid Artery; Plaque Characterization; Scatter Size; Longitudinal Movement; Intima-Media Thickness;

    Abstract : Atherosclerosis is one of the major causes of death in the world. It is an inflammatory disease in the arteries which causes a gradual increase in arterial wall thickness and stiffness. Eventually a plaque could be formed, protruding into the artery and partially occluding the blood flow. READ MORE
