  2. 6. Improved dose response modeling for normal tissue damage and therapy optimization

    Author : Magdalena Adamus-Górka; Bengt K. Lind; Anders Brahme; Panayiotis Mavroidis; Randall K. Ten Haken; Stockholms universitet; []
    Keywords : Normal tissue complications; radiobiological models; dose-response; volume effect; spinal cord; effective FSU size; medicinsk strålningsfysik; Medical Radiation Physics;

    Abstract : The present thesis is focused on the development and application of dose response models for radiation therapy. Radiobiological models of tissue response to radiation are an integral part of the radiotherapeutic process and a powerful tool to optimize tumor control and minimize damage to healthy tissues for use in clinical trials.

  4. 7. Orthopaedic measurements with computed radiography. Methodological development, accuracy, and radiation dose with special reference to the weight-bearing lower extremity and the dislocating patella

    Author : Jan Sanfridsson; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; digital.; computer-assisted; Picture Archiving and Communication Systems; computed radiography; radiography; effective dose; radiation dosage; measurements; biomechanics; dislocating patella; musculoskeletal; patellofemoral joint; Knee joint; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : The overall aim of this study was to develop and evaluate a measurement system for computed radiography (CR) and Picture Archiving and Communication Systems (PACS), permitting measurements of long distances and angles in and between related images. The developed measurement system, which was based on the QUESTOR Precision Radiography (QPR) system, was applied to the weight-bearing knee with special reference to the dislocating patella.

  5. 8. Irradiation of members of the general public from radioactive caesium following the Chernobyl reactor accident. Field studies in a highly contaminated area in the Bryansk region, Russia

    Author : Charlotte Thornberg; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; body burden; Effective dose; Cs-137; urinary excretion; Cs-134; biological half-time; Chernobyl; breast milk; Medicine human and vertebrates ; internal irradiation; external irradiation; TLD; Clinical physics; radiology; medical instrumentation; tomography; Medicin människa och djur ; Physics; Fysik;

    Abstract : From 1990 to 1998, estimations of the effective dose from external as well as internal irradiation from 137Cs and 134Cs were carried out for inhabitants in rural villages in the Bryansk region, Russia, highly contaminated due to the Chernobyl accident in 1986. The villages were situated about 180 km from the Chernobyl power plant and the deposition of 137Cs was in the range 0. READ MORE

  6. 9. Radiation exposure of human populations in villages in Russia and Belarus affected by fallout from the Chernobyl reactor

    Author : Christian Bernhardsson; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chernobyl; caesium; effective dose; OSL; NaCl; TL; LiF; radiation protection survey instruments; deposition variability; long-term series;

    Abstract : A quarter of a century has elapsed since the catastrophe at the nuclear power plant in Chernobyl. The radioactive fallout affected all the European countries and most severely the three countries of Belarus, Russia and Ukraine. READ MORE

  7. 10. Pharmacokinetics and dosimetry in intraperitoneal radioimmunotherapy with 211At

    Author : Elin Cederkrantz; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; astatine-211; radioimmunotherapy; alpha-emitter; ovarian cancer; MX35; pharmacokinetics; dosimetry; effective dose;

    Abstract : The prognosis for patients diagnosed with disseminated cancer is often poor. Radioimmunotherapy (RIT) is a new approach to treat disseminated disease. The aim is to target tumor cells with monoclonal antibodies (mAbs) labeled with radionuclides which release cytotoxic particle radiation upon decay. The radionuclide 211At, with half-life 7. READ MORE
