  1. 1. Determination of absorbed dose in fields of fast neutrons

    Författare :Anders Montelius; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutron dosimetry; finite volumes; interface effects; marrow dose; chord length distributions;

    Sammanfattning : Analytical models have been developed to solve energy deposition problems in finite detectors and near interfaces in beams of fast neutrons. Dose expressions have been derived, which are suitable for numerical evaluation. The detectors or volumes of interest have been characterized by distributions of chord length along which the particles travel. LÄS MER

  3. 2. Radiation dose and related risk in interventional cardiology

    Författare :Angeliki Karambatsakidou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cardiac catheterization procedures are classified as high radiation dose procedures, European Directive 2013/59/Euratom, and may result in skin injuries (deterministic effects) and/or increased cancer risk (stochastic effects). The radiation-induced effects can be expressed differently depending on whether the patient is a child or an adult. LÄS MER

  4. 3. Dosimetry of Radionuclide Therapy with 177Lu-octreotate

    Författare :Mattias Sandström; Hans Lundqvist; Mark Lubberink; Sven-Erik Strand; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 177Lu-octreotate; Absorbed dose; Neuroendocrine tumour; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : In radionuclide therapy it is still common to administer standard activities or to scale administered activity with blunt parameters such as body weight or surface area. This is not ideal because, due to considerable variation in kinetics, large safety margins have to be applied to avoid radiation damage to healthy organs, which causes under-treatment of many patients.

  5. 4. Survival of onlay bone grafts. A study in the adult rat

    Författare :Monica Gordh; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; polytetrafluoroethylene; artificial; membrane; immunohistochemistry; cortical perforations; bone morphogenetic protein; bone marrow; bone; bone grafts; Odontologi; stomatology; Odontology; skull; tibia;

    Sammanfattning : The aim of this thesis was to study onlay bone grafting in the adult rat to improve graft incorporation and perservation of graft size. In 167 adult isogeneic lewis rats, the size maintenance and bone formation at the graft-host interface of uni- and bicortical onlays positioned in various environments and treatments were investigated.

  7. 5. High-Dose Radioimmunotherapy and Extracorporeal Depletion in A Syngeneic Rat Tumor Model

    Författare :Linda Mårtensson; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : ABSTRACT Radioimmunotherapy (RIT) consists of using monoclonal antibodies (mAbs) recognizing tumor-selective antigens, as carriers of cytotoxic radionuclides to tumor tissue. RIT has been effective in lymphoma but less successful in solid tumors. LÄS MER
