  1. 1. Aspects on Image Quality in Radiologic Evaluation of the Urinary Tract

    Författare :Margareta Lundin; Anders Persson; Torbjörn Andersson; Håkan Geijer; Anders Magnuson; Jan Persliden; Anders Magnusson; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The focus of this document is on image quality as one of the factors fundamental for the diagnostic process. With the rising number of procedures and the trend towards more complicated examinations, urinary tract investigations was chosen in this work as a good clinical model for evaluation of the factors influencing image quality and of the ways of evaluating image quality.

  2. 2. Vad händer i själva verket? : Om styrning och handlingsutrymme i Skolverket under åren 1991–2014

    Författare :Eva Maria Magnusson; Anders Forssell; Anders Ivarsson Westerberg; Magnus Frostenson; Uppsala universitet; []
    Nyckelord :Governance; control; discretion; state agencies; Skolverket; old public management; new public management; new public governance; agents; actors; arenas; Business Studies; Företagsekonomi;

    Sammanfattning : This thesis deals with questions of governance, control and discretion in state agencies. It is grounded on a case study of the Swedish National Agency for Education (Skolverket), from its prelude in the late 1980s, to its start in 1991, through several governments, seven ministers and four direktor generals, up tp 2014.

  3. 3. CT Urography : Efforts to Reduce the Radiation Dose

    Författare :Pär Dahlman; Anders Magnusson; Anders Sundin; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urinary tract malignancy; renal cell carcinoma; urography; x-ray computed tomography; radiation dosage; dose escalation; hematuria diagnosis; Diagnostic radiology; Diagnostisk radiologi; Radiology; Radiologi;

    Sammanfattning : Computed tomography urography (CTU) is today the imaging method used to investigate patients with suspected urinary tract malignancy, replacing the old imaging method intravenous pyelography (IVP) about a decade ago. The downside of this shift was that the effective radiation dose to the examined patient was eight times higher for CTU compared to IVP. LÄS MER

  4. 4. CT with 3D-Image Reconstructions in Preoperative Planning

    Författare :Angeliki Dimopoulou; Anders Magnusson; Anders Persson; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT Angiography; 3D-image reconstructions; haemodialysis; AVF AVG; DIEP flap; surgery time; complicated renal calculi; PNL; true nonenhanced images; virtual nonenhanced images; CT Urography; Radiology; Radiologi;

    Sammanfattning : Computed tomography is one of the most evolving fields of modern radiology. The current CT applications permit among other things angiography, 3D image reconstructions, material decomposition and tissue characterization. CT is an important tool in the assessment of specific patient populations prior to an invasive or surgical procedure. LÄS MER

  5. 5. Branch Identification in Elastic Stability Analysis

    Författare :Anders Magnusson; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; hydraulics; Mechanical engineering; Produktionsteknik; Production technology; FEM; computer simulation; bifurcation; stability; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Sammanfattning : In this thesis, methods to determine the static postbuckling behaviour of elastic structures undergoing large deformations, are considered and developed. Since the governing non-linear equations usually becomes too complex to be handled analytically, the main focus has been on developing methods that can be incorporated into a numerical solution scheme, such as the finite element method.
