  2. 1. Dose Management in Diagnostic Radiology - application of the DICOM imaging standard and a Monte Carlo dose engine for exposure surveillance

    Author : Hans-Erik Källman; Anders Ahnesjö; Hilde M. Olerud; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; metadata; DICOM; radiation safety; Monte Carlo; source model; patient model; optimization; justification; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : Ionizing radiation is used in diagnostic radiology with a large contribution to the health of the patients. The regulations to limit the detrimental effects, e.g. cancer induction, are based on recommendations from the International Commission on Radiological Protection (ICRP). READ MORE

  4. 2. Quality Assurance in Radiotherapy - Development and evaluation of new tools for improved patient safety

    Author : Fredrik Nordström; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; monitor unit verification; in vivo dosimetry; real-time verification; gel dosimetry; 4D dosimetry; IMRT; VMAT; data integrity; radiotherapy; Quality assurance;

    Abstract : Preparation for radiotherapy is a complex procedure that involves many different technologies and groups of professionals. The rapid development and introduction of new technologies throughout the last decade have made it possible to deliver highly conformal, individually-shaped dose distributions with high accuracy.

  5. 3. Computational patient models for simulation of dynamic gamma-camera imaging : Application to renography and peptide receptor radionuclide therapy

    Author : Gustav Brolin; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear medicine; Gamma camera; Renography; Radionuclide therapy; Internal dosimetry; Pharmacokinetics;

    Abstract : Many nuclear medicine investigations rely on gamma-camera imaging to study and quantify the distribution of radiopharmaceuticals or radionuclides in the patient as a function of time. This is typically used for diagnostic studies of physiological functions or for calculation of absorbed doses following radionuclide therapy. READ MORE

  6. 4. Evaluation of methods of measuring wear of polyethylene acetabular components intotal hip arthroplasty

    Author : Charles R Bragdon; Göteborgs universitet; []
    Keywords : Total hip replacement; polyethylene; wear; radiostereometric analysis; radiograph;

    Abstract : Background: The introduction of highly cross-linked, wear resistant polyethylene acetabularcomponents for clinical use in total hip replacements has intensified the interest in and need for highlyaccurate methods of measuring wear from clinical radiographs. There are several methods currentlyavailable for measuring the relative displacement of the femoral head into the acetabular componentresulting from the combination of plastic deformation and wear of the polyethylene bearing surface.
