  • Assessment and comparison of target registration accuracy in surgical instrument tracking technologies 
    Teatini, Andrea; Perez de Frutos, Javier; Langø, Thomas; Edwin, Bjørn; Elle, Ole Jacob (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Image guided surgery systems aim to support surgeons by providing reliable pre-operative and intra-operative imaging of the patient combined with the corresponding tracked instrument location. The image guidance is based ...
  • Influence of sampling accuracy on augmented reality for laparoscopic image-guided surgery 
    Teatini, Andrea; Perez de Frutos, Javier; Eigl, Benjamin; Aghayan, Davit; Pelanis, Egidijus; Lai, Marco; Kumar, Rahul Prasanna; Palomar, Rafael; Edwin, Bjørn; Elle, Ole Jacob (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Purpose This study aims to evaluate the accuracy of point-based registration (PBR) when used for augmented reality (AR) in laparoscopic liver resection surgery. Material and methods The study was conducted in three ...
  • A novel method for planning liver resections using deformable Bezier surfaces and distance maps 
    Palomar, Rafael; Alaya Cheikh, Faouzi; Edwin, Bjørn; Fretland, Åsmund Avdem; Beghdadi, Azeddine; Elle, Ole Jakob (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Background and Objective: For more than a decade, computer-assisted surgical systems have been helping surgeons to plan liver resections. The most widespread strategies to plan liver resections are: drawing traces in ...
  • The effect of intraoperative imaging on surgical navigation for laparoscopic liver resection surgery 
    Teatini, Andrea; Pelanis, Egidijus; Aghayan, Davit; Kumar, Rahul Prasanna; Palomar, Rafael; Fretland, Åsmund Avdem; Edwin, Bjørn; Elle, Ole Jacob (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Conventional surgical navigation systems rely on preoperative imaging to provide guidance. In laparoscopic liver surgery, insufflation of the abdomen (pneumoperitoneum) can cause deformations on the liver, introducing ...
  • Towards a video quality assessment based framework for enhancement of laparoscopic videos 
    Khan, Zohaib Amjad; Beghdadi, Azeddine; Alaya Cheikh, Faouzi; Kaaniche, Mounir; Pelanis, Egidijus; Palomar, Rafael; Fretland, Åsmund Avdem; Edwin, Bjørn; Elle, Ole Jacob (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)
    Laparoscopic videos can be affected by different distortions which may impact the performance of surgery and introduce surgical errors. In this work, we propose a framework for automatically detecting and identifying such ...
  • Use of mixed reality for improved spatial understanding of liver anatomy 
    Pelanis, Egidijus; Kumar, Rahul Prasanna; Aghayan, Davit; Palomar, Rafael; Fretland, Åsmund Avdem; Brun, Henrik; Elle, Ole Jacob; Edwin, Bjørn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Introduction: In liver surgery, medical images from pre-operative computed tomography and magnetic resonance imaging are the basis for the decision-making process. These images are used in surgery planning and guidance, ...
  • Use of mixed reality for surgery planning: Assessment and development workflow 
    Kumar, Rahul Prasanna; Pelanis, Egidijus; Bugge, Robin Antony Birkeland; Brun, Henrik; Palomar, Rafael; Aghayan, Davit; Fretland, Åsmund Avdem; Edwin, Bjørn; Elle, Ole Jacob (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Meticulous preoperative planning is an important part of any surgery to achieve high levels of precision and avoid complications. Conventional medical 2D images and their corresponding three-dimensional (3D) reconstructions ...
