  1. 1. Imaging imagining actions

    Detta är en avhandling från Umeå : Integrativ medicinsk biologi

    Författare :CJ Olsson; Umeå universitet.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mental training; motor training; novices; imaging; athletes; fMRI; internal imagery; motor representation; brain systems; practice; learning; transfer; active; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi;

    Sammanfattning : Mental training has been studied extensively for the past century but we are still not completely sure how it affects brain and behavior. The aim of this doctoral thesis was to examine one aspect of mental training i.e. motor imagery. LÄS MER

  2. 2. Imaging Anxiety Neurochemistry in Anxiety Disorders Assessed by Positron Emission Tomography

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Andreas Frick; Uppsala universitet.; [2015]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Fear; Brain; Serotonin; Neurokinin; Substance P; Psychology; Psykologi;

    Sammanfattning : Anxiety disorders, including social anxiety disorder (SAD) and posttraumatic stress disorder (PTSD) are common and disabling conditions. Largely based on animal and pharmacological studies, both the serotonergic and substance P/neurokinin-1 (SP/NK1) systems have been implicated in their underlying pathology. LÄS MER

  3. 3. Coherent Diffractive Imaging with X-ray Lasers

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Max Felix Hantke; Uppsala universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; coherent diffractive X-ray imaging; lensless imaging; coherent X-ray diffractive imaging; flash diffractive imaging; single particle imaging; aerosol injection; electrospray injection; substrate-free sample delivery; carboxysome; phase retrieval; X-ray diffraction software; X-ray free-electron laser; XFEL; FEL; CXI; CDI; CXDI; FXI;

    Sammanfattning : The newly emerging technology of X-ray free-electron lasers (XFELs) has the potential to revolutionise molecular imaging. XFELs generate very intense X-ray pulses and predictions suggest that they may be used for structure determination to atomic resolution even for single molecules. LÄS MER

  4. 4. Necrotising Enterocolitis epidemiology and imaging

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Margareta Ahle; Linköpings universitet.; Linköpings universitet.; Region Östergötland.; [2017]

    Sammanfattning : Necrotising enterocolitis (NEC) is a potentially devastating intestinal inflammation of multifactorial aetiology in premature or otherwise vulnerable neonates. Because of the broad spectrum of presentations, diagnosis and timing of surgical intervention may be challenging, and imaging needs to be an integrated part of management. LÄS MER

  5. 5. Laboratory X-Ray Phase-Contrast Imaging Methods and Comparisons

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

    Författare :Tunhe Zhou; KTH.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray imaging; Phase-contrast; Liquid-metal-jet source; Propagation-based imaging; Grating-based imaging; Speckle-based imaging; Physics; Fysik;

    Sammanfattning : X-ray phase-contrast imaging has seen rapid development in recent decades due to its superior performance in imaging low-absorption objects, compared to traditional attenuation x-ray imaging. Having higher demand on coherence, x-ray phase-contrast imaging is performed mostly at synchrotrons. LÄS MER
