    • 3D ultrasound reconstruction algorithms from analog and digital data 

      Solberg, Ole Vegard; Lindseth, Frank; Bø, Lars Eirik; Muller, Sebastien; Meland, Janne Beate Lervik; Tangen, Geir Arne; Hernes, Toril A. Nagelhus (Journal article; Peer reviewed, 2010)
      Freehand 3D ultrasound is increasingly being introduced in the clinic for diagnostics and image-assisted interventions. Various algorithms exist for combining 2D images of regular ultrasound probes to 3D volumes, being ...

    • Airway segmentation and centerline extraction from thoracic CT - Comparison of a new method to state of the art commercialized methods 

      Reynisson, Pall Jens; Scali, Marta; Smistad, Erik; Hofstad, Erlend Fagertun; Leira, Håkon Olav; Lindseth, Frank; Hernes, Toril A. Nagelhus; Amundsen, Tore; Sorger, Hanne; Langø, Thomas (Peer reviewed; Journal article, 2015)
      Introduction Our motivation is increased bronchoscopic diagnostic yield and optimized preparation, for navigated bronchoscopy. In navigated bronchoscopy, virtual 3D airway visualization is often used to guide a bronchoscopic ...

    • Efficiency of ultrasound training simulators: Method for assessing image realism 

      Bø, Lars Eirik; Gjerald, Sjur Urdson; Brekken, Reidar; Hernes, Toril A. Nagelhus; Tangen, Geir Arne (Journal article; Peer reviewed, 2010)
      Although ultrasound has become an important imaging modality within several medical professions, the benefit of ultrasound depends to some degree on the skills of the person operating the probe and interpreting the image. ...

    • 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 ...

    • Simulation-based Training and Assessment in Minimally Invasive Surgery Exploration and Validation 

      Våpenstad, Cecilie (Doctoral theses at NTNU;2019:323, Doctoral thesis, 2019)
      Changes in surgical techniques and public attention to surgeons’ competencies in general, created a growth in simulation-based training in the late 90’s. The introduction of minimally invasive surgery, with its distinct ...

    • Ultrasound in image-guided spine surgery: Enabling technologies and first steps 

      Bø, Lars Eirik (Doctoral theses at NTNU;2018:257, Doctoral thesis, 2018)
      Most people experience back pain at some point in their life. While most of these conditions are treated nonoperatively, surgical treatment has been shown to be both effective and cost effective compared to nonoperative ...

    • Versatile robotic probe calibration for position tracking in ultrasound imaging 

      Bø, Lars Eirik; Hofstad, Erlend Fagertun; Lindseth, Frank; Hernes, Toril A. Nagelhus (Journal article; Peer reviewed, 2015)
      Within the field of ultrasound-guided procedures, there are a number of methods for ultrasound probe calibration. While these methods are usually developed for a specific probe, they are in principle easily adapted to other ...
