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 ... -
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 (Journal article; Peer reviewed, 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 ... -
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 ... -
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 ... -
