• 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 ...
    • Geometric Modeling for Planning of Liver Resection Procedures 

      Palomar, Rafael (Doctoral theses at NTNU;2018:174, Doctoral thesis, 2018)
    • 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 ...
    • In-Body to On-Body Ultra WidebandPropagation Model Derived from Measurementsin Living Animals 

      Floor, Pål Anders; Chavez-Santiago, Raul; Brovoll, Sverre; Aardal, Øyvind; Bergsland, Jacob; Grymyr, Ole-Johannes; Halvorsen, Per Steinar; Palomar, Rafael; Plettemeier, Dirk; Hamran, Svein-Erik; Ramstad, Tor Audun; Balasingham, Ilangko (Journal article; Peer reviewed, 2015)
      Ultra wideband (UWB) radio technology for wireless implants has gained significant attention. UWB enables the fabrication of faster and smaller transceivers with ultra low power consumption, which may be integrated into ...
    • Registration of MR to Percutaneous Ultrasound of the Spine for Image-Guided Surgery 

      Bø, Lars Eirik; Palomar, Rafael; Selbekk, Tormod; Reinertsen, Ingerid (Chapter, 2014)
      One of the main limitations of today’s navigation systems for spine surgery is that they often are not available until after the bone surface has been exposed. Also, they lack the capability of soft tissue imaging, both ...
    • 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; 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 ...
    • 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; 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, ...
    • Validation of stereo vision based liver surface reconstruction for image guided surgery 

      Teatini, Andrea; Wang, Congcong; Palomar, Rafael; Alaya Cheikh, Faouzi; Edwin, Bjørn; Elle, Ole Jacob (Chapter, 2018)
      Image guided surgery systems aim to provide navigation to surgeons in order to improve accuracy and safety of the procedures. Through stereo reconstruction algorithms, it is possible to generate 3D surfaces intra-operatively ...
