    • A multimodal image guiding system for Navigated Ultrasound Bronchoscopy (EBUS): A human feasibility study 

      Sorger, Hanne; Hofstad, Erlend Fagertun; Amundsen, Tore; Langø, Thomas; Bakeng, Janne Beate Lervik; Leira, Håkon Olav (Journal article; Peer reviewed, 2017)
      Background Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is the endoscopic method of choice for confirming lung cancer metastasis to mediastinal lymph nodes. Precision is crucial for correct ...

    • 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 ...

    • Anthropomorphic liver phantom with flow for multimodal image-guided liver therapy research and training 

      Rethy, Anna; Sæternes, Jørn Ove; Halgunset, Jostein; Mårvik, Ronald; Hofstad, Erlend Fagertun; Sanchez-Margallo, Juan A.; Langø, Thomas (Journal article; Peer reviewed, 2017)
      Purpose The objective of this study was to develop a multimodal, permanent liver phantom displaying functional vasculature and common pathologies, for teaching, training and equipment development in laparoscopic ultrasound ...

    • Intraoperative localized constrained registration in navigated bronchoscopy 

      Hofstad, Erlend Fagertun; Sorger, Hanne; Bakeng, Janne Beate Lervik; Gruionu, Lucian; Leira, Håkon Olav; Amundsen, Tore; Langø, Thomas (Journal article; Peer reviewed, 2017)
      Purpose One of the major challenges in electromagnetic navigated bronchoscopy is the navigation accuracy. An initial rigid image-to-patient registration may not be optimal for the entire lung volume, as the lung tissue ...

    • Laboratory test of Single Landmark registration method for ultrasound-based navigation in laparoscopy using an open-source platform 

      Perez de Frutos, Javier; Hofstad, Erlend Fagertun; Solberg, Ole Vegard; Tangen, Geir Arne; Lindseth, Frank; Langø, Thomas; Elle, Ole Jacob; Mårvik, Ronald (Journal article; Peer reviewed, 2018)
      Purpose Test the feasibility of the novel Single Landmark image-to-patient registration method for use in the operating room for future clinical trials. The algorithm is implemented in the open-source platform CustusX, a ...

    • 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)

    • Multimodal Phantom of Liver Tissue 

      Chmarra, Magdalena Karolina; Hansen, Rune; Mårvik, Ronald; Langø, Thomas (Journal article, 2013)
      Medical imaging plays an important role in patients' care and is continuously being used in managing health and disease. To obtain the maximum benefit from this rapidly developing technology, further research is needed. ...

    • Navigated retrograde endoscopic myotomy (REM) for the treatment of therapy-resistant achalasia 

      Pham, Khanh Do-Cong; Havre, Roald Flesland; Langø, Thomas; Hofstad, Erlend Fagertun; Tangen, Geir Arne; Mårvik, Ronald; Pham, T.; Gilja, Odd Helge; Hatlebakk, Jan Gunnar; Viste, Asgaut (Journal article; Peer reviewed, 2018)
      Background In achalasia, muscle spasm may involve the proximal esophagus. When the muscle spasm is located in the proximal esophagus, conventional per oral endoscopic myotomy (POEM) may not be sufficient to relieve symptoms. ...

    • 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 ...
