  1. 26. Assessment of cerebrospinal fluid system dynamics : novel infusion protocol, mathematical modelling and parameter estimation for hydrocephalus investigations

    Författare :Kennet Andersson; Anders Eklund; Karin Wårdell; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicinsk teknik; hydrocefalus; infusionstest; utflödeskonduktans; systemidentifiering; Medical technology; Medicinsk teknik;

    Sammanfattning : Patients with idiopathic normal pressure hydrocephalus (INPH) have a disturbance in the cerebrospinal fluid (CSF) system. The treatment is neurosurgical – a shunt is placed in the CSF system. The infusion test is used to assess CSF system dynamics and to aid in the selection of patients that will benefit from shunt surgery. LÄS MER

  3. 27. Simulation used as a learning approach in nursing education : Students’ experiences and validation of evaluation questionnaires

    Författare :Randi Tosterud; Marie-Louise Hall-Lord; Kerstin Petzäll; Birgitta Hedelin; Anna Löfmark; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; debriefing; evaluation questionnaires; fidelity; nursing students; experiences; psychometric testing; simulation; Nursing Science; Omvårdnad;

    Sammanfattning : The overall aim was to investigate bachelor nursing students’ experiences with simulation as a learning approach conducted under various conditions. Additionally, the aim was to translate and validate questionnaires for the evaluation of simulation in a Norwegian context.Methods: Quantitative and qualitative methods were used. LÄS MER

  4. 28. DIXI – a Hybrid Pixel Detector for X-ray Imaging

    Författare :Fredrik Edling; Richard Brenner; Leif Gustafsson; Camilla Rönnqvist; Peter Fischer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; hybrid pixel detector; photon-counting; X-ray; imaging; simulation; Strålningsvetenskap; Radiation biology; Strålningsbiologi;

    Sammanfattning : Medical X-ray imaging is an important tool in diagnostic radiology. The ionising-radiation dose to the patient is justified by the clinical benefit of the examination. Nonetheless, detectors that operate at even lower doses and provide more information to the radiologist are desired. LÄS MER

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

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

    Sammanfattning : 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.

  7. 30. Studies on the alpha-recoil implantation of 214Pb and 210Pb in glass surfaces,Implications for retrospective radon measurements

    Författare :Birgitta Roos; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; unattached activity; attached activity; retrospective radon measurement; long-lived radon progenies; short-lived radon progenies; deposition velocity; implantation; 222Rn; glass surface; etching; simulation; Nuclear physics; Kärnfysik;

    Sammanfattning : Glass sheets are often used in radon surveys to estimate retrospective radon concentrations, as radon progenies are embedded in the upper surface layer. The implanted activity is influenced by a variety of different environmental conditions. LÄS MER
