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. ... -
Can a Dinosaur Think? Implementation of Artificial Intelligence in Extracorporeal Shock Wave Lithotripsy
Muller, Sebastien; Abildsnes, Håkon; Østvik, Andreas; Kragset, Oda; Gangås, Inger Sofie Hovd; Birke, Harriet; Langø, Thomas; Arum, Carl-Jørgen (Peer reviewed; Journal article, 2021)Background: Extracorporeal shock wave lithotripsy (ESWL) of kidney stones is losing ground to more expensive and invasive endoscopic treatments. Objective: This proof-of-concept project was initiated to develop artificial ... -
Mediastinal lymph nodes segmentation using 3D convolutional neural network ensembles and anatomical priors guiding
Bouget, David Nicolas Jean-Mar; Pedersen, André; Vanel, Johanna; Leira, Håkon Olav; Langø, Thomas (Peer reviewed; Journal article, 2022)As lung cancer evolves, the presence of potentially malignant lymph nodes must be assessed to properly estimate disease progression and select the best treatment strategy. A method for accurate and automatic segmentation ... -
A new removable airway stent
Amundsen, Tore; Sørhaug, Sveinung; Leira, Håkon Olav; Tyvold, Stig Sverre; Langø, Thomas; Hammer, Tommy Arild; Manstad-Hulaas, Frode; Mattsson, Erney (Peer reviewed; Journal article, 2016)Background Malignant airway obstruction is a feared complication and will most probably occur more frequently in the future because of increasing cancer incidence and increased life expectancy in cancer patients. Minimal ... -
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 ... -

Målet er å øke antallet kliniske studier og forbedre pasientbehandlingen. -
Prediction of guidewire-induced aortic deformations during EVAR: a finite element and in vitro study
Emendi, Monica; Støverud, Karen-Helene; Tangen, Geir Arne; Ulsaker, Håvard; Manstad-Hulaas, Frode; Di Giovanni, Pierluigi; Dahl, Sigrid Kaarstad; Langø, Thomas; Prot, Victorien Emile (Peer reviewed; Journal article, 2023)Introduction and aims: During an Endovascular Aneurysm Repair (EVAR) procedure a stiff guidewire is inserted from the iliac arteries. This induces significant deformations on the vasculature, thus, affecting the pre-operative ... -
