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 staging ... -
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 ... -
Bronchoscopy using a head-mounted mixed reality device—a phantom study and a first in-patient user experience
Kildahl-Andersen, Arne; Hofstad, Erlend Fagertun; Sorger, Hanne; Amundsen, Tore; Langø, Thomas; Leira, Håkon Olav; Kiss, Gabriel Hanssen (Peer reviewed; Journal article, 2023)Background: Bronchoscopy for peripheral lung lesions may involve image sources such as computed tomography (CT), fluoroscopy, radial endobronchial ultrasound (R-EBUS), and virtual/electromagnetic navigation bronchoscopy. ... -
Development of navigated ultrasound bronchoscopy
Sorger, Hanne (Doctoral theses at NTNU;2018:78, Doctoral thesis, 2018)Lung cancer staging of mediastinal lymph nodes with convex probe endobronchial ultrasound transbronchial needle aspiration (CP-EBUS-TBNA) is a challenge to the bronchoscopist. Small, multiple targets are involved, and the ... -
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 ... -
Kontaktfri søvnmonitori diagnostikk og oppfølging av søvnapné. Nytteverdi og gjennomførbarhet.
Fossland, Vigdis (Master thesis, 2023)Sammendrag Introduksjon Hovedtemaet i denne masteroppgaven er utprøving av ny teknologi i søvndiagnostikk, utført i pasientens hjem. Vi gjennomførte en klinisk studie der hensikten var å undersøke nytteverdien av søvndata ... -
Lungekreftutredning ved Sykehuset Levanger og St. Olavs Hospital i perioden 2008-2018 – Kvalitet og utviklingstrender.
Klonteig, Kristoffer Bolt-Hansen (Master thesis, 2020)Bakgrunn Tidlig, rask og presis vevsdiagnose, samt korrekt utvelgelse av pasienter til kurativ behandling tilstrebes for bedre pasientoverlevelse ved lungekreft. Tradisjonelt sett har bronkoskopi vært den foretrukne ... -
Macro-indentation testing of soft biological materials and assessment of hyper-elastic material models from inverse finite element analysis
Ayyalasomayajula, Venkat Siva Radha Krishna; Ervik, Øyvind; Sorger, Hanne; Skallerud, Bjørn Helge (Peer reviewed; Journal article, 2024)Mechanical characterization of hydrogels and ultra-soft tissues is a challenging task both from an experimental and material parameter estimation perspective because they are much softer than many biological materials, ... -
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 ...
