  2. 1. Optimisation of radiographic imaging by means of factorial experiments

    Author : Eva Norrman; Jan Persliden; Andreas Oberstedt; Bertil Axelsson; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Fysik; Physics;

    Abstract : In the optimisation process of radiographic imaging, factorial designed experiments can be applied. The parameters (factors) are varied together instead of one at a time, making it possible to discover interactions between the factors as well as main influences of them on the result variable.

  4. 2. Metal artifacts in computed tomography : impact of reduction methods on image quality and radiotherapy treatment planning

    Author : Karin Andersson; Per Thunberg; Eva Norrman; Jan Persliden; Anders Tingberg; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; computed tomography; metal artifacts; image quality; visual grading analysis; radiotherapy; proton therapy; hip prosthesis; dental implants;

    Abstract : Degradation of image quality by metal artifacts is a common problem in computed tomography (CT) imaging, which can limit the diagnostic value of a CT examination and also introduce inaccuracies in radiotherapy (RT) treatment planning. In recent years, commercial metal artifact reduction (MAR) methods have been launched by several CT vendors. READ MORE

  5. 3. The regulation of factor Va activity by activated protein C -Importance of the individual activated protein C cleavage sites in factor Va

    Author : Eva Norström; Malmö Klinisk kemi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellulära vätskor; Hematologi; extracellular fluids; Haematology; activated protein C resistance; activated protein C; Blood coagulation; Factor V;

    Abstract : The subject of this thesis is the activated protein C (APC)-mediated inactivation of factor Va. The activated form of factor V (FVa) is a procoagulant cofactor for Factor Xa (FXa) in the conversion of prothrombin to thrombin. READ MORE
