    • Construct validity of eoSim - a low-cost and portable laparoscopic simulator 

      Mansoor, Saira Mauland; Våpenstad, Cecilie; Mårvik, Ronald; Glomsaker, Tom Birger; Bliksøen, Marte (Peer reviewed; Journal article, 2019)
      Purpose: To examine the construct validity of the low-cost, portable laparoscopic simulator eoSim using motion analysis. Material and methods: Novice and experienced surgeons (≤ 100 and >100 laparoscopic procedures ...

    • Influence of patient-specific rehearsal on operative metrics and technical success for endovascular aneurysm repair 

      Våpenstad, Cecilie; Lamøy, Siv Marit Jonli; Aasgaard, Frode; Manstad-Hulaas, Frode; Aadahl, Petter; Søvik, Edmund; Stensæth, Knut Haakon (Peer reviewed; Journal article, 2020)
      Introduction: Patient-specific rehearsal (PsR) is a recent technology within virtual reality (VR) simulation that lets the operators train on patient-specific data in a simulated environment prior to the procedure. ...

    • Lack of transfer of skills after virtual reality simulator training with haptic feedback 

      Våpenstad, Cecilie; Hofstad, Erlend Fagertun; Bø, Lars Eirik; Kuhry, Esther; Johnsen, Gjermund; Mårvik, Ronald; Langø, Thomas; Hernes, Toril A. Nagelhus (Journal article; Peer reviewed, 2017)
      Background and objective: Virtual reality (VR) simulators enrich surgical training and offer training possibilities outside of the operating room (OR). In this study, we created a criterion-based training program on a VR ...

    • A novel clip-on device for electromagnetic tracking in endobronchial ultrasound bronchoscopy 

      Kildahl-Andersen, Arne; Hofstad, Erlend Fagertun; Peters, Karlijn; Van Beek, Gregory; Sorger, Hanne; Amundsen, Tore; Langø, Thomas; Leira, Håkon Olav (Peer reviewed; Journal article, 2022)
      Introduction The established method for assessment of mediastinal and hilar lymph nodes is endobronchial ultrasound bronchoscopy (EBUS) with needle aspirations. Previously, we presented an electromagnetic navigation ...

    • Optimal timing of assessment tasks depending on experience level of surgical trainees 

      Våpenstad, Cecilie; Hofstad, Erlend Fagertun; Bernstein, Tor Eivind; Aadahl, Petter; Johnsen, Gjermund; Mårvik, Ronald (Peer reviewed; Journal article, 2019)
      Introduction: Box trainers with motion analysis are important add-ons to surgical training and skills assessment outside the operating room, given that they exhibit construct validity. Material and methods: Four different ...

    • Peripheral tumour targeting using open-source virtual bronchoscopy with electromagnetic tracking: a multi-user pre-clinical study 

      Jaeger, Herman Alexander; Trauzettel, Fabian; Nardelli, Pietro; Daverieux, Federico; Hofstad, Erlend Fagertun; Leira, Håkon Olav; Kennedy, Marcus P; Langø, Thomas; Cantillon-Murphy, Pádraig (Journal article; Peer reviewed, 2018)
      Objectives: The goal was to demonstrate the utility of open-source tracking and visualisation tools in the targeting of lung cancer. Material and methods: The study demonstrates the first deployment of the Anser electromagnetic ...

    • 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 ...

    • Pulmonologist evaluation on new CT visualization for guidance to lung lesions during bronchoscopy 

      Reynisson, Pall Jens; Leira, Håkon Olav; Langø, Thomas; Tangen, Geir Arne; Hatlen, Peter; Amundsen, Tore; Hofstad, Erlend Fagertun (Journal article; Peer reviewed, 2018)
      Objective: Endoluminal visualization in virtual and video bronchoscopy lacks information about the surrounding structures, and the traditional 2 D axial, coronal and sagittal CT views can be difficult to interpret. To ...
