  1. 1. Targeting Non-obvious Errors in Death Certificates

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lars Age Johansson; Uppsala universitet.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Social medicine; Cause of death; Death certificates; Medical records; Mortality statistics; Quality control; Medical record linkage; Socialmedicin;

    Sammanfattning : Mortality statistics are much used although their accuracy is often questioned. Producers of mortality statistics check for errors in death certification but current methods only capture obvious mistakes. This thesis investigates whether non-obvious errors can be found by linking death certificates to hospital discharge data. LÄS MER

  2. 2. Key Data for the Reference and Relative Dosimetry of Radiotherapy and Diagnostic and Interventional Radiology Beams

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Hamza Benmakhlouf; Stockholms universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Backscatter factors; Diagnostic radiology dosimetry; Mass energy-absorption coefficients; Monte Carlo; Output correction factors; Radiotherapy dosimetry; Reference dosimetry; Relative dosimetry; Small photon fields; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : Accurate dosimetry is a fundamental requirement for the safe and efficient use of radiation in medical applications. International Codes of Practice, such as IAEA TRS-398 (2000) for radiotherapy beams and IAEA TRS-457 (2007) for diagnostic radiology beams, provide the necessary formulation for reference and relative dosimetry and the data required for their implementation.

  3. 3. Evaluation of Errors and Limitations in Ultrasound Imaging Systems

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

    Författare :Mattias Mårtensson; KTH.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Other technology Medical engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Medicinsk teknik;

    Sammanfattning : There are binding regulations requiring safety and efficacy aspects of medical devices. The requirements ask for documentation that the devices are safe and effective for their intended use, i.e. if a device has a measuring function it must be correct. LÄS MER

  4. 4. Diagnostic precision and sex differences in quantitative cardiovascular magnetic resonance

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Molecular Medicine and Surgery

    Författare :Jannike Nickander; Karolinska Institutet.; Karolinska Institutet.; [2018]

    Sammanfattning : Correct medical treatment necessitates a correct diagnosis. Cardiac imaging aims to establish an accurate diagnosis without performing unnecessary invasive procedures. LÄS MER

  5. 5. Droplet size, concentration, and temperature mapping in sprays using SLIPI-based techniques

    Detta är en avhandling från Division of Combustion Physics, Department of Physics, Lund University

    Författare :Yogeshwar Nath Mishra; [2018-01-22]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sprays; Optical measurements; Laser diagnostic; Droplet size; Temperature; Fysicumarkivet A:2018:Mishra;

    Sammanfattning : Structured laser illumination planar imaging (SLIPI) is a technique capable of suppressing multiple light scattering effects in optically dense sprays, resulting in spray images without blurs and with enhanced contrast. The novelty of the work presented in this thesis concerns the applications of a variety of SLIPI-based techniques for the measurement of droplet size, droplet concentration, and liquid temperature in atomizing sprays.
