  1. 6. Practical Implementation of Quality Assurance Guidelines for Hyperthermia Therapy

    Författare :Mattia de Lazzari; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hyperthermia; quality assurance; tissue-mimicking phantoms;

    Sammanfattning : Hyperthermia therapy (HT) has been proven to be a potent enhancer of chemotherapy and radiotherapy in numerous clinical trials. The effectiveness of HT is strictly dependent on the administered thermal dose, which, in turn, is dependent on the quality of the therapeutic heat applied to the patient. LÄS MER

  3. 7. Quality assurance for magnetic resonance imaging (MRI) in radiotherapy

    Författare :Mary Adjeiwaah; Tufve Nyholm; Anders Garpebring; Joakim Jonsson; Sofie Ceberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; MRI; radiotherapy; RT; geometric distortions; magnetic susceptibility; B0 maps; quality assurance; radiofysik; radiation physics;

    Sammanfattning : The use of Magnetic Resonance Imaging (MRI) in the radiotherapy (RT) treatment planning workflow is increasing. MRI offers superior soft-tissue contrast compared to Computed Tomography (CT) and therefore improves the accuracy in target volume definitions. LÄS MER

  4. 8. Strategic and clinical quality indicators in surgical nursing care

    Författare :Ewa Idvall; Linköpings universitet; []
    Nyckelord :quality assurance; health care; quality indicators; nursing care; focus groups; pain; postoperative; MEDICINE; MEDICIN;

    Sammanfattning : The general aim of this study was to identify strategic and clinical quality indicators in surgical nursing care. The methods used were a literature review, focus group interviews and a survey with a questionnaire. LÄS MER

  5. 9. Quality Assurance of Time Critical Data Using Adaptive Data Delivery Mechanisms in Smart Grids

    Författare :Yiming Wu; Lars Nordström; Chen-Ching Liu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; time critical data quality; adaptive mechanisms; quality assurance; Smart Grid; information resiliency; data accuracy; end-to-end latency; cyber-security; substation automation; power system communication; Electrical Engineering; Elektro- och systemteknik; Industrial Information and Control Systems; Industriella informations- och styrsystem;

    Sammanfattning : Smart grids are proposed to integrate renewable energy and to improve the efficiency of power system operation. The challenges of integrating renewable energy are the inherent fluctuations of generation which are difficult to predict which may lead to challenges to the safe operation of power systems. LÄS MER

  7. 10. Facilitating Feature-Oriented Quality Assurance in Low-Maturity Variant-rich Systems

    Författare :Mukelabai Mukelabai; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Variant-Rich Systems; Cloned Projects; Quality Assurance; Feature Location; Test Case Reuse; Recommender System;

    Sammanfattning : Context: Many software systems exist in several variants customized for specific stakeholder requirements, such as different market segments or hardware constraints. This customization introduces a high level of complexity that renders traditional single-system quality assurance techniques inapplicable, since they need to consider variations and constraints between a system’s features—a.
