  1. 1. Effects of high intensity focused ultrasound on the intervertebral disc

    Författare :Johan K Persson; Ian McCarthy; Carina Forslund; Björn Strömqvist; Lars Lidgren; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; tomography; radiology; Clinical physics; Biofysik; Biophysics; Thermal therapy; Disc herniation; Intervertebral disc; High intensity focused ultrasound; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; thermal therapy; HIFU; disc herniation;

    Sammanfattning : The purpose of this study was to study and try to optimise high intensity focused ultrasound treatment of the intervertebral disc. We demonstrated that it was possible to heat intervertebral discs with HIFU delivered by 50 or 5 mm diameter ultrasound transducers. LÄS MER

  2. 2. Boron neutron capture therapy : Synthesis of boronated amines- and DNA intercalating agents for potential use in cancer therapy

    Författare :Hadi Ghaneolhosseini; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Chemistry; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : Boron Neutron Capture Therapy is a binary cancer treatment modality, involving the delivery of a suitable boron compound to tumour cells followed by irradiation of the tumour by thermal neutrons. Boronated agents can selectively be delivered to tumour cells either directly with tumour-specific boron compounds, or by use of targeting strategies. LÄS MER

  3. 3. On modelling and simulation of perfused tissue during thermal treatment : thermal analysis of blood perfusion and lesioning during ablative neurosurgery

    Författare :Joakim Wren; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Thermal treatment means therapy for which heat is the therapeutic agent. During treatment, the tissue temperature is increased to an injurious temperature (higher than 43 °C for the most widely used treatments). The aim is to reach necrotic temperature in the treatment area and non-lethal temperature outside the same. LÄS MER

  4. 4. Photodynamic therapy and laser-based diagnostic studies of malignant tumours

    Författare :Ingrid Wang; Medicinskt lasercentrum; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protoporphyrin IX PpIX ; delta -aminolevulinic acid ALA ; photosensitizer; basal cell carcinoma BCC ; Photodynamic therapy PDT ; laser-induced fluorescence LIF ; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

    Sammanfattning : Two non-thermal regimens of light interaction with biological tissue, that are in a natural way connected, are discussed in the present thesis. These are photodynamic therapy (PDT) for the treatment of malignant tumours and laser-induced fluorescence (LIF) for tissue characterization. LÄS MER

  5. 5. Methods, Instrumentation and Mechanisms for Optical Characterization of Tissue and Treatment of Malignant Tumours

    Författare :Sara Pålsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; temperature; perfusion; PDT; photodynamic therapy; mechanisms; tissue characterization; instrumentation; optical biopsy; fluorescence spectroscopy; spectroscopy techniques; Raman spectroscopy; interstitial photodynamic therapy; photodynamic threshold dose; Atomic and molecular physics; Atom- och molekylärfysik;

    Sammanfattning : In this thesis, different optical methods utilising visible light for characterization of tissue have been developed and evaluated. The feasibility of many of these methods has been demonstrated in the laboratory or in animal experiments. LÄS MER
