    Sammanfattning : The full-width-at-half-maximum of the point spread functions for a pixellated cadmium telluride detector exposed to gammas from a 140.5 keV Tc-99m source are modelled in GATE, at a detector-collimator distance of 5 cm, and collimator-source distances of 5 cm and 10 cm, with lead pinholes of diameter 1.0 mm, 1.5 mm, 2.

  3. 8. Experimental Radionuclide Therapy Quantitative Pinhole planar and SPECT imaging, aiming for dosimetry based on biokinetic modeling and small animal S-values

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Fredrik Henricsson; [2005]
    Nyckelord :Nukleärmedicin; Medicine and Health Sciences;

    Sammanfattning : New radionuclide therapies in humans should be preceded by experimental animal therapies, in order to evaluate the efficacy of the new therapy regime. These experimental studies have to be performed with a reliable and accurate quantification system, with properties that have been evaluated and where possible flaws have been corrected for. LÄS MER

  4. 9. Volume Estimation of Airbags: A Visual Hull Approach

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Manne Anliot; [2005]
    Nyckelord :Bildanalys; Airbag Reconstruction; Volume Estimation; Visual Hull; Pinhole Camera Model; Simulated Annealing; Delaunay Triangulation; Best-Camera-Pose; Bildanalys;

    Sammanfattning : This thesis presents a complete and fully automatic method for estimating the volume of an airbag, through all stages of its inflation, with multiple synchronized high-speed cameras. Using recorded contours of the inflating airbag, its visual hull is reconstructed with a novel method: The intersections of all back-projected contours are first identified with an accelerated epipolar algorithm.
