• 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; 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 ...
    • Cross modality guided liver image enhancement of CT using MRI 

      Naseem, Rabia; Alaya Cheikh, Faouzi; Beghdadi, Azeddine; Elle, Ole Jakob; Lindseth, Frank (Peer reviewed; Journal article, 2019)
      Low contrast Computed Tomographic (CT) images often hamper the diagnosis of critical tumors found in various human organs. Contrast enhancement schemes play significant role in improving the visualization of these structures. ...
    • High-Performance Computation of Bézier Surfaces on Parallel and Heterogeneous Platforms 

      Palomar, Rafael; Gómez-Luna, Juan; Alaya Cheikh, Faouzi; Olivares-Bueno, Joaquín; Elle, Ole Jakob (Journal article; Peer reviewed, 2017)
      Bézier surfaces are mathematical tools employed in a wide variety of applications. Some works in the literature propose parallelization strategies to improve performance for the computation of Bézier surfaces. These ...
    • Sensor Control in Robotic Surgery 

      Elle, Ole Jakob (Doktoravhandlinger ved NTNU, 1503-8181; 2004:27, Doctoral thesis, 2004)
      This doctoral thesis investigates sensor control in robotic surgery. At the present state of the art, robotic technology for surgical applications can broadly be divided into four main classes: • Robotic assistance • ...
