2. 1. k-space Models in MRI Using the Concept of Partitions, Applications with special reference to Overhauser-enhanced techniques

   Author : J Stefan Petersson; Malmö Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; model; Physics; k-space; magnetic resonance imaging; Overhauser; simulation; Fysik;

   Abstract : A new model describing the image formation in magnetic resonance imaging (MRI) has been developed. The k-space description of MRI pulse sequences is expanded by introducing new dimensions to describe the phase dispersion due to flow, acceleration, jerk, diffusion and magnetic field inhomogeneities.

4. 2. Developing knee joint osteoarthritis: Clinical, radiographical and biochemical features

   Author : Ingemar Petersson; Reumatologi och molekylär skelettbiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone markers; cartilage markers; WOMAC; SF-36; function; health status quality-of-life; radiography; epidemiology; knee pain; Knee joint; osteoarthritis; bone scan; Skeleton; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi;

   Abstract : The aim of this project was to study clinical, radiographical and biochemical features of developing, symptomatic knee osteoarthritis (OA) prospectively in individuals aged 35-54 from the general population. A questionnaire to a random sample of 2 000 individuals in the district of Laholm, Sweden, identified 279 individuals (15% of the population) with chronic (>3 months) knee pain. READ MORE

5. 3. Fast and Accurate 4D Flow MRI for Cardiovascular Blood Flow Assessment

   Author : Sven Petersson; Tino Ebbers; Oliver Wieben; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The study of blood flow is essential in understanding the physiology and pathophysiology of the cardiovascular system. Small disturbances of the blood flow may over time evolve and contribute to cardiovascular pathology. READ MORE

6. 4. Dendritic and axonal ion channels supporting neuronal integration : From pyramidal neurons to peripheral nociceptors

   Author : Marcus Petersson; Erik Fransén; Theodore Cummins; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ion channels; computational modeling; simulations; dendrites; axons; TRP; hippocampus; C-fiber nociceptors; pain;

   Abstract : The nervous system, including the brain, is a complex network with billions of complex neurons. Ion channels mediate the electrical signals that neurons use to integrate input and produce appropriate output, and could thus be thought of as key instruments in the neuronal orchestra. READ MORE

7. 5. Space and Time Configurations in Telemedicine

   Author : Jesper Petersson; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Telemedicine; ICT; Time; Space; Science Technology Studies; Technofeminism; Actor-Network Theory;

   Abstract : Sammanfattning: Denna licentiatavhandling är en socioteknisk och spatiotemporal studie av praktiserande av hälso‐ och sjukvård med hjälp av informations‐ och kommunikationsteknik (IKT), eller s k telemedicin. IKT förknippas ofta med möjligheten att överkomma tid och rum och tillåta åtkomst av sådant som finns någon annanstans. READ MORE
