  2. 1. Quality assurance for magnetic resonance imaging (MRI) in radiotherapy

    Author : Mary Adjeiwaah; Tufve Nyholm; Rob HN Tijssen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic resonance imaging; Radiotherapy; geometric distortions; patient-induced susceptibilities MR-only; radiofysik; radiation physics;

    Abstract : Magnetic resonance imaging (MRI) utilizes the magnetic properties of tissues to generate image-forming signals. MRI has exquisite soft-tissue contrast and since tumors are mainly soft-tissues, it offers improved delineation of the target volume and nearby organs at risk. READ MORE

  4. 2. Advancements in DSC and BOLD perfusion imaging: Acquisition, analysis and clinical application

    Author : Jonathan Arvidsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic Resonance Imaging; Cerebral Blood Flow; Cerebral Blood Volume; Time To Peak; Biophysical modelling; Signal representation; MRI;

    Abstract : This thesis is focused on perfusion MRI techniques and topics related to image acquisition, analysis and clinical applications. The first half of the thesis is focused on dynamic susceptibility contrast (DSC) MRI, a technique which is based on the contrast enhancements caused by an intravenously administered paramagnetic contrast agent.

  5. 3. Developing educational computer-assisted simulations : Exploring a new approach to researching learning in collaborative health care simulation contexts

    Author : Lars O. Häll; Tor Söderström; Limin Gu; Patrik Hernwall; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; education; computer simulation; collaboration; health care; context; design; ecology of resources.; pedagogik; Education;

    Abstract : Health care education is developing and simulations, in different guises, are gaining increasing attention as a means of overcoming tensions between instructional models and educational objectives. The role of simulations is, however, yet to be fully defined and will be dependent on the actual impact simulations on educational practice. READ MORE
