  2. 1. Investigating Phantom Motor Execution as treatment of Phantom Limb Pain

    Author : Eva Lendaro; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Randomized Controlled Trial; Phantom Limb Sensations; Phantom Limb Pain; EEG.; Phantom Motor Execution; Amputation;

    Abstract : Phantom Limb Pain (PLP) is commonly suffered by people with amputations and even though it has been studied for centuries, it remains a mysterious object of debate among researchers. For one thing, despite the vast number of proposed PLP treatments, no therapy has so far proved to be reliably effective. READ MORE

  5. 3. On the use of Phantom Motor Execution for the treatment of Phantom Limb Pain

    Author : Eva Lendaro; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amputation; Randomized Controlled Clinical Trial.; Phantom Limb Sensations; Phantom Limb Pain; Phantom Motor Execution;

    Abstract : Phantom limb pain (PLP) is a common complaint among amputees and despite having been studied for centuries, it remains a mysterious object of debate among researcher. To date, a vast number of ways to treat PLP has been proposed in the literature, however none of them has proven to be universally effective, thus creating uncertainty on how to operate clinically.

  6. 4. Model-based Approaches to Diffuse Optical Imaging and Dosimetry

    Author : Johan Axelsson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photodynamic therapy; diffuse light propagation; fluorescence; imaging; dosimetry; inverse problem;

    Abstract : The work within this thesis investigates Photodynamic therapy and Fluorescence imaging for therapeutics and visualization of deeply embedded lesions. Photodynamic therapy (PDT) is a cancer treatment modality that can eradicate tumors when light, a photosensible drug and oxygen are present. READ MORE

  7. 5. Image Quality Optimisation and Dose Management in CT, SPECT/CT, and PET/CT

    Author : Marcus Söderberg; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT; SPECT; PET; dosimetry; image quality; optimisation; dose reduction; automatic exposure control; contrast medium; phantom; image reconstruction; human observer;

    Abstract : The significant increase in the use of CT, alone or combined with SPECT or PET, has raised concerns about patient radiation exposure and the consequent increased risk of malignancy later in life. The overall objective of this work was to evaluate and optimise different approaches for minimising patient radiation absorbed dose and maintaining or improving image quality in CT, SPECT/CT, and PET/CT.
