  4. 2. Corrections for improved quantitative accuracy in SPECT and planar scintigraphic imaging

    Author : Anne Larsson; Lennart Johansson; Katrine Åhlström Riklund; Bertil Axelsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Quantitative SPECT; scintigraphic imaging; attenuation correction; scatter correction; collimator-detector response; septal penetration; background correction; Monte Carlo simulation; Radiological physics; Radiofysik;

    Abstract : A quantitative evaluation of single photon emission computed tomography (SPECT) and planar scintigraphic imaging may be valuable for both diagnostic and therapeutic purposes. For an accurate quantification it is usually necessary to correct for attenuation and scatter and in some cases also for septal penetration. READ MORE

  5. 3. Diffusion MRI: Aspects of Reproducibility and Novel Segmented 2D and 3D Approaches for Higher Resolution and Geometric Fidelity

    Author : Jens Johansson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diffusion-weighted imaging; 3D-DWI; Time-Dependent ADC; DWi; Diffusion Time; Multi-Shot DWI; Echo- Planar Imaging; Geometric Distortion;

    Abstract : Diffusion-weighted imaging (DWI) is a very useful tool for non-invasive imaging and clinical investigation of the human body. It provides data of the water diffusion process. READ MORE

  6. 4. Laser Diagnostics and Chemical Modeling of Combustion and Catalytic Processes

    Author : Michael Försth; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catalysis; platinum; OH; elastic light scattering; planar LIF; fuel spray; surface reactions; imaging; Chemkin; hydroxyl; stagnation flow; gas-phase chemistry;

    Abstract : The H2+1/2O2 H2O reaction on hot platinum surfaces has been studied. A stagnation flow geometry was used with a gas mixture of H2 and O2 at subatmospheric pressures. READ MORE

  7. 5. Activity quantification based on scintillation camera imaging - Application to 111In/90Y radioimmunotherapy

    Author : David Minarik; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radioimmunotherapy; bremsstrahlung imaging; activity quantification; SPECT; conjugate view; Yttrium;

    Abstract : Radionuclide therapy (RNT), is important for the treatment of certain benign and malignant diseases. 90Y-Zevalin™ therapy has become an established method of treating patients with non-Hodgkin B-cell lymphoma. READ MORE
