Periodic Reporting for period 1 - HiPerNav (High Performance Soft-tissue Navigation)
Reporting period: 2016-11-01 to 2018-10-31
Objectives: The overall goal of HiPerNav is to successfully train and educate young researchers (ESRs) in the multidisciplinary field of image-guided interventions. The scientific and clinical goal is to further develop solutions for computer assisted and image guided surgical and interventional procedures for the treatment of primary and secondary liver cancer. It is aimed at improving eligibility and survival prognosis of cancer patients.
The project is organized through a consortium comprising 5 European universities, 2 university hospitals, 2 research organizations and 5 industrial companies, whereas one SME. Oslo University Hospital is the coordinator. In total 16 young researchers (ESRs) will be financed through the project.
The HiPerNav project aims to improve important bottlenecks in soft-tissue navigation:
– effective pre-operative model and planning
– accurate and fast intra-operative model update
– accurate and fast model-to-patient registration
– intuitive user-interaction and effective workflow
– high performance computing by use of GPU
The 14 organizations in the consortium are particularly selected being one of the leading institutions within their field of expertise, and they are all selected to fill specific competences needed to meet the HiPerNav overall goal. The consortium partner organizations are: Oslo University Hospital, University Hospital Bern, NTNU, SINTEF, INRIA, University of Bern, University Paris13, University of Delft, University of Cordoba, CAScination, SIEMENS, NVIDIA, Yes!Delft and Innovation Norway.
