  3. 2. SPECT Imaging using Pinhole Collimation : System Design and Simulation Studies for Pre-Clinical and Clinical Imaging

    Författare :Mikael Peterson; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pinhole SPECT tomography; Nuclear medicine imaging; Monte Carlo-based image reconstruction;

    Sammanfattning : The focus of this dissertation is the use of pinhole collimation in Nuclear Medicine. A pinhole is a single aperture in an opaque material that is placed between the detector and source of interest, and photons must pass through the hole to reach the detector. The choices of pinhole parameters, e.g. LÄS MER

  4. 3. Learning and understanding for quality improvement under different conditions : An analysis of quality registry-based collaboratives in acute and chronic care

    Författare :Anette Peterson; Boel Andersson Gäre; Johan Thor; Berith Hedberg; Soffia Gudbjörnsdottir; Helle Wijk; Jönköping University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The demands that are placed on healthcare systems continue to increase, but several studies show that patient care and healthcare system outcomes are not as good as they could be. To come to terms with these problems, many stakeholders turn to systematic quality improvement methods. LÄS MER

  5. 4. Induction Machine Speed Estimation - Observations on Observers

    Författare :Bo Peterson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; robotics; Automation; Elektronik och elektroteknik; Electronics and Electrical technology; estimation; sensorless control; observer; induction machine; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : This work focuses on observers estimating flux linkage and speed for induction machines, mainly in the low speed region. With speed estimation, sensorless control is possible, meaning that the speed of induction machines without mechanical speed sensors can be controlled. LÄS MER
