  1. 1. Physical Aspects of Thermotherapy - A study of heat transport with a view to treatment optimisation

    Författare :Johan Olsrud; Sektion V; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance; non-invasive; temperature; coagulation; prostatic; menorrhagia; liver tumour; finite element method FEM ; thermal conductivity; intracavitary; interstitial; laser; Thermotherapy; hyperthermia; MRI; Medicine human and vertebrates ; Medicin människa och djur ; Physics; Fysik; Fysicumarkivet A:1998:Olsrud;

    Sammanfattning : Local treatment with the aim to destruct tissue by heating (thermotherapy) may in some cases be an alternative or complement to surgical methods, and has gained increased interest during the last decade. The major advantage of these, often minimally-invasive methods, is that the disease can be controlled with reduced treatment trauma and complications. LÄS MER

  3. 2. Interstitial Laser Thermotherapy of Liver Tumours. Methodology and Application

    Författare :Páll Helgi Möller; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Resection; Liver; Neoplasm; Blood flow; Monitoring; Feedback control; Light penetration; Bare fibre; Sapphire probe; Nd:YAG laser; Interstitial thermotherapy; Hyperthermia; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Interstitial laser thermotherapy (ILT) is a method well suited for selective local destruction of malignant tumours. In the present work, a laser thermotherapy system based on feedback temperature control of energy delivery (through computerised feedback system) was developed. LÄS MER

  5. 4. Interstitial laser thermotherapy (ILT) of breast cancer - Methodology and immunological responce

    Författare :Kristin Huld-Haraldsdottir; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; Laser thermotherapy; Minimally invasive treatment; Tumour immunology; Thermal treatment; Tumour size; Magnetic resonance imaging;

    Sammanfattning : Interstitial laser thermotherapy (ILT) is an attractive form of local therapy against cancer because of its anti-tumor immune activity. The aim of this work was to evaluate ILT in breast cancer with respect to technique, changes in tissue immunocompetent cells and effect on prognosis. LÄS MER

  7. 5. Medical Laser-Induced Thermotherapy - Models and Applications

    Författare :Christian Sturesson; Lund Kirurgi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; blood perfusion; mathematical modelling; liver tumours; Atomic and molecular physics; benign prostatic hyperplasia; Atom- och molekylärfysik; Fysicumarkivet A:1998:Sturesson; hyperthermia; Coagulation; tissue optical properties;

    Sammanfattning : Heat has long been utilised as a therapeutic tool in medicine. Laser-induced thermotherapy aims at achieving the local destruction of lesions, relying on the conversion of the light absorbed by the tissue into heat. In interstitial laser-induced thermotherapy, light is focused into thin optical fibres, which are placed deep into the tumour mass. LÄS MER
