• A Weighted Histogram-Based Tone Mapping Algorithm for CT images 

      Völgyes, David; Martinsen, Anne Catrine Trægde; Stray-Pedersen, Arne; Waaler, Dag; Pedersen, Marius (Journal article; Peer reviewed, 2018)
      Computed Tomography (CT) images have a high dynamic range, which makes visualization challenging. Histogram equalization methods either use spatially invariant weights or limited kernel size due to the complexity of pairwise ...
    • Applicability of a clinical cardiac CT protocol in post mortem studies 

      Völgyes, David; Pedersen, Marius; Stray-Pedersen, Arne; Waaler, Dag; Martinsen, Anne Catrine Trægde (Journal article; Peer reviewed, 2018)
      Objective Confirmation whether an optimized clinical cardiac CT scan protocol is also optimal for post mortem cardiac CT scans without iodine contrast or the reconstruction parameters should be changed. Materials ...
    • Image De-Quantization Using Plate Bending Model 

      Völgyes, David; Martinsen, Anne Catrine Trægde; Stray-Pedersen, Arne; Waaler, Dag; Pedersen, Marius (Journal article; Peer reviewed, 2018)
      Discretized image signals might have a lower dynamic range than the display. Because of this, false contours might appear when the image has the same pixel value for a larger region and the distance between pixel levels ...
    • Image quality in forensic CT imaging 

      Völgyes, David (Doctoral theses at NTNU;2018:294, Doctoral thesis, 2018)
      What factors affect the diagnostic image quality in forensic computed tomography (CT) imaging? In this thesis I briefly present the main steps from CT scanning to diagnostics. The thesis is built on four core papers. The ...
