    • Prediction of guidewire-induced aortic deformations during EVAR: a finite element and in vitro study 

      Emendi, Monica; Støverud, Karen-Helene; Tangen, Geir Arne; Ulsaker, Håvard; Manstad-Hulaas, Frode; Di Giovanni, Pierluigi; Dahl, Sigrid Kaarstad; Langø, Thomas; Prot, Victorien Emile (Peer reviewed; Journal article, 2023)
      Introduction and aims: During an Endovascular Aneurysm Repair (EVAR) procedure a stiff guidewire is inserted from the iliac arteries. This induces significant deformations on the vasculature, thus, affecting the pre-operative ...

    • Psychomotor skills assessment by motion analysis in minimally invasive surgery on an animal organ 

      Hofstad, Erlend Fagertun; Våpenstad, Cecilie; Bø, Lars Eirik; Langø, Thomas; Kuhry, Esther; Mårvik, Ronald (Journal article; Peer reviewed, 2017)
      Background: A high level of psychomotor skills is required to perform minimally invasive surgery (MIS) safely. To be able to measure these skills is important in the assessment of surgeons, as it enables constructive ...

    • Pulmonary Tumor Segmentation Utilizing Mixed-Supervision in a Teacher-Student Framework 

      Fredriksen, Vemund; Sevle, Svein Ole Matheson (Master thesis, 2021)
      Kreft er en av de fremste dødsårsakene i den utviklede verden, og den mest dødelige typen er lungekreft. Kliniske eksperter er avhengig av avanserte medisinske bildebehandlingsteknikker og visuell analyse for å oppdage ...
