    • 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, ...

    • 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 ...
