    • Evaluation of Metallurgical Bonding for Ultrasound Transducers 

      Bolstad, Per Kristian (Doctoral dissertations at the University of South-Eastern Norway;188, Doctoral thesis, 2024)
      Common ultrasound transducers use a piezoelectric element to convert between electrical and mechanical energy. The piezoelectric layer is sandwiched between acoustic matching and backing layers to maximize energy transfer ...

    • Layer-specific strain and strain rate : Estimation using miniature transducers attached to the epicardium 

      Nguyen, Thu Thuy (Doctoral dissertations at the University of South-Eastern Norway;68, Doctoral thesis, 2020)
      Reliable methods to asses ventricular function during and after cardiac surgery are essential tools to evaluate patient prognosis. We presented an ultrasound system to monitor cardiac motion using miniature transducers ...
