  2. 1. Interpretation of diagnostic information given patient characteristics

    Author : Martin Gellerstedt; Hans Åhlfeldt; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; reference values; diagnostic theory; diagnostic tests; partitioning; prevalence function; reference values; diagnostic theory; diagnostic tests; partitioning; prevalence function;

    Abstract :  The aim with this thesis was to describe, exemplify and develop theory for reference values and diagnostic tests, especially focusing on the variability between individuals. To facilitate interpretation of medical information it is common to establish some kind of limit. There are several different rationales for the choice of such a limit. READ MORE

  4. 2. Perioperative myocardial infarction in cardiac surgery : a diagnostic dilemma

    Author : Lars-Göran Dahlin; Torbjörn Ivert; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Perioperative myocardial infarction remains a major cause of morbidity and mortality after cardiac surgery. In spite of this there is no consensus regarding diagnostic criteria and consequently the reported incidence varies widely. READ MORE

  5. 3. Effective use of X rays in diagnostic radiology : Guidance for the optimisation of image quality and absorbed dose in the patient by use of a Monte Carlo computational model of the imaging chain

    Author : Michael Sandborg; Heang-Ping Chan; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The primary objective of this thesis is to give guidance for the reduction of absorbed dose in the patient and the improvement of image quality by the optimisation of the various parameters which control the performance of the radiological imaging system. The optimisation means that image quality (contrast in screen-film imaging and signal-to-noise ratio in digital imaging) is kept constant and combinations of operating parameters which yields the lowest mean absorbed dose in the patient is determined.

  7. 5. An electrostatic sampling device for point-of-care detection of bioaerosols

    Author : Laila Ladhani; Wouter van der Wijngaart; Jorma Keskinen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrostatic sampling; bioaerosols; point-of-care; breath sampling; electrostatic precipitation; microfluidic collection; corona discharge; air sampling; non-invasive diagnostics; exhaled breath analysis; on-site detection; aerosol sampling; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Bioaerosols are not only a significant factor of air quality but contribute greatly to the spread of infectious diseases, specifically through expired pathogen-laden aerosols. Clear examples of airborne transmission include: the recent influenza pandemic of 2009, the ongoing tuberculosis epidemic, and yearly norovirus out- breaks, which affect millions of people worldwide and pose serious threats to public healthcare systems.
