• 3-D Doppler imaging in cardiac applications using high frame-rate sequences 

      Fiorentini, Stefano (Doctoral theses at NTNU;2020:60, Doctoral thesis, 2020)
      Several decades after the establishment of Doppler ultrasound, quantification and imaging of blood flow using Doppler-based techniques continue to face multiple challenges. Out-of-plane flow, transit-time broadening and ...
    • Combining Automatic Angle Correction and 3-D Tracking Doppler for the Assessment of Aortic Stenosis Severity 

      Fiorentini, Stefano; Espeland, Torvald; Berg, Erik Andreas Rye; Aakhus, Svend; Torp, Hans; Avdal, Jørgen (Journal article; Peer reviewed, 2019)
      Aortic valve stenosis (AS) is a narrowing of the aortic valve opening, which causes increased load on the left ventricle. Untreated, this condition can eventually lead to heart failure and death. According to current ...
    • Maximum velocity estimation in coronary arteries using 3D tracking Doppler 

      Fiorentini, Stefano; Saxhaug, Lars Mølgaard; Holte, Espen; Bjåstad, Tore Grüner; Torp, Hans; Avdal, Jørgen (Journal article, 2018)
      Several challenges currently prevent the use of Doppler echocardiography to assess blood flow in the coronary arteries. Due to the anatomy of the coronary tree, out-of-plane flow and high beam-to-flow angles easily occur. ...
