• 3D Myocardial Mechanical Wave Measurements: Toward In Vivo 3D Myocardial Elasticity Mapping 

      Salles, Sebastien; Espeland, Torvald; Rodriguez-Molares, Alfonso; Aase, Svein Arne; Hammer, Tommy; Støylen, Asbjørn; Aakhus, Svend; Løvstakken, Lasse; Torp, Hans (Peer reviewed; Journal article, 2020)
      Objectives This study aimed to investigate the potential of a novel 3-dimensional (3D) mechanical wave velocity mapping technique, based on the natural mechanical waves produced by the heart itself, to approach a noninvasive ...
    • 3D Speckle-Tracking: Sub-voxel Techniques and Tracking Accuracy 

      Bostad, Ingvild Haraldsen (Master thesis, 2006)
      Speckle tracking is a method that is useful for examining myocardial function. The method allows the cardiologist examine the left ventricular wall function when there are indications of a myocardial infarction. The method ...
    • Clutter Filter Wave Imaging 

      Salles, Sebastien; Løvstakken, Lasse; Aase, Svein Arne; Bjåstad, Tore Grüner; Torp, Hans (Journal article; Peer reviewed, 2019)
      The elastic properties of human tissue can be evaluated through the study of mechanical wave propagation captured using high frame rate ultrasound imaging. Methods such as block-matching or phase-based motion estimation ...
    • Real-Time Echocardiography Guidance for Optimized Apical Standard Views 

      Pasdeloup, David Francis Pierre; Olaisen, Sindre Hellum; Østvik, Andreas; Sæbø, Sigbjørn; Pettersen, Håkon Neergaard; Holte, Espen; Grenne, Bjørnar; Stølen, Stian Bergseng; Smistad, Erik; Aase, Svein Arne; Dalen, Håvard; Løvstakken, Lasse (Journal article; Peer reviewed, 2022)
    • Real-time Standard View Classification in Transthoracic Echocardiography using Convolutional Neural Networks 

      Østvik, Andreas; Smistad, Erik; Aase, Svein Arne; Haugen, Bjørn Olav; Løvstakken, Lasse (Journal article; Peer reviewed, 2018)
      Transthoracic echocardiography examinations are usually performed according to a protocol comprising different probe postures providing standard views of the heart. These are used as a basis when assessing cardiac function, ...
    • Ultrasound View Detection 

      Horejs, Jan (Master thesis, 2010)
      The goal of this project is to establish effective ultrasound view detection between apical, parasternal long axis and parasternal short axis view. The chosen approach in this project is to represent a shape of the cavity ...
