• 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 ...
    • Accuracy of electromagnetic tracking with a prototype field generator in an interventional OR setting 

      Bø, Lars Eirik; Leira, Håkon Olav; Tangen, Geir Arne; Hofstad, Erlend Fagertun; Amundsen, Tore; Langø, Thomas (Journal article; Peer reviewed, 2012)
      Purpose: The authors have studied the accuracy and robustness of a prototype electromagnetic window field generator (WFG) in an interventional radiology suite with a robotic C-arm. The overall purpose is the development ...
    • 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 ...
    • 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 ...
    • Real time ultrasound simulation: Application to a medical training simulator 

      Bø, Lars Eirik (Master thesis, 2008)
      As ultrasound technology today finds new applications and becomes available to more and more users, the demand for good training procedures and material increases. This has motivated a research project aimed at developing ...
    • Registration of MR to Percutaneous Ultrasound of the Spine for Image-Guided Surgery 

      Bø, Lars Eirik; Palomar, Rafael; Selbekk, Tormod; Reinertsen, Ingerid (Chapter, 2014)
      One of the main limitations of today’s navigation systems for spine surgery is that they often are not available until after the bone surface has been exposed. Also, they lack the capability of soft tissue imaging, both ...
    • 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 ...
