• The Generalized Contrast-to-Noise Ratio: A Formal Definition for Lesion Detectability 

      Molares, Alfonso Rodrígues; Rindal, Ole Marius Hoel; D´Hooge, Jan; Måsøy, Svein-Erik; Austeng, Andreas; Bell, Muyinatu A. Lediju; Torp, Hans (Peer reviewed; Journal article, 2020)
      In the last 30 years, the contrast-to-noise ratio (CNR) has been used to estimate the contrast and lesion detectability in ultrasound images. Recent studies have shown that the CNR cannot be used with modern beamformers, ...
    • Inner-Cycle Phases Can Be Estimated from a Single Inertial Sensor by Long Short-Term Memory Neural Network in Roller-Ski Skating 

      Meyer, Frederic; Lund-Hansen, Magne; Seeberg, Trine Margrethe; Kocbach, Jan; Sandbakk, Øyvind; Austeng, Andreas (Peer reviewed; Journal article, 2022)
      Objective: The aim of this study was to provide a new machine learning method to determine temporal events and inner-cycle parameters (e.g., cycle, pole and ski contact and swing time) in cross-country roller-ski skating ...
    • The dark region artifact in adaptive ultrasound beamforming 

      Rindal, Ole Marius Hoel; Rodriguez-Molares, Alfonso; Austeng, Andreas (Journal article; Peer reviewed, 2017)
      An undesired effect, the dark region artifact (DRA), has been under-communicated in our research community. The DRA appear next to acoustically strong targets for some of the many adaptive beamformers introduced in the ...
    • The influence of speckle statistics on contrast metrics in ultrasound imaging 

      Hverven, Stine Myhre; Rindal, Ole Marius Hoel; Rodriguez-Molares, Alfonso; Austeng, Andreas (Journal article; Peer reviewed, 2017)
      Adaptive beamformers aim for improved resolution and contrast in the ultrasound images, and their performance is typically benchmarked using metrics such as contrast ratio (CR) and contrast-to-noise ratio (CNR). Using ...
    • The UltraSound ToolBox 

      Rodriguez-Molares, Alfonso; Rindal, Ole Marius Hoel; Bernard, Olivier; Nair, Arun; Bell, Muyinatu A. Lediju; Liebgott, Herve; Austeng, Andreas; Løvstakken, Lasse (Journal article; Peer reviewed, 2017)
      We present the UltraSound ToolBox (USTB), a processing framework for ultrasound signals. USTB aims to facilitate the comparison of imaging techniques and the dissemination of research results. It fills the void of tools ...
    • Validation of temporal parameters within the skating sub-techniques when roller skiing on a treadmill, using inertial measurement units 

      Meyer, Frederic; Seeberg, Trine Margrethe; Kocbach, Jan; Danielsen, Jørgen; Sandbakk, Øyvind; Austeng, Andreas (Peer reviewed; Journal article, 2022)
      The aim of this study was to develop and validate a method using inertial measurements units (IMUs) to determine inner-cycle parameters (e.g., cycle, poles and skis contact, and swing time) and the main sub-techniques ...
