  2. 1. On the use of radiography and radiation dose consideration in orthodontic treatment

    Author : Christina Stervik; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; effective dose; errors; estimated risk; intra-oral radiograph; organ dose; orthodontic treatment; orthodontists; panoramic image; questionnaires; radiation doses;

    Abstract : The aims of this thesis were to analyse the use of radiography and radiation risk associated with orthodontic treatment. Study I measured absorbed doses to radiosensitive organs in the head and neck in an anthropomorphic phantom head using thermo¬luminescent dosimeters (TLDs) from digital intra-oral and panoramic radiography.

    Abstract : Introduction: Poor quality health care is a serious silent public health problem worldwide, resulting in deaths, disabilities and long hospital stays with unnecessary costs. It affects patients in all countries regardless of their level of development. READ MORE

  5. 3. Targeting Non-obvious Errors in Death Certificates

    Author : Lars Age Johansson; Ragnar Westerling; Eric Jougla; Uppsala universitet; []
    Keywords : Social medicine; Cause of death; Death certificates; Medical records; Mortality statistics; Quality control; Medical record linkage; Socialmedicin;

    Abstract : 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. READ MORE

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

    Author : Hamza Benmakhlouf; Pedro Andreo; Klemens Zink; Stockholms universitet; []
    Keywords : 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; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : 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.

  7. 5. Evaluation of Errors and Limitations in Ultrasound Imaging Systems

    Author : Mattias Mårtensson; Lars-Åke Brodin; Peter Rask; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical engineering; Medicinsk teknik;

    Abstract : 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. READ MORE
