The CT physics and technology research group was established in 2012 with an ambition to establish a leading centre for CT physics and technology research in Norway. There has been little focus on CT research in Norway to date, but given a steady increase in the number of CT examinations, with about 80% of the total population radiation exposure from medical procedures stemming from CT , an increased research effort in this field is clearly needed. . The research topics addressed by the group include the development of new imaging methods, clinical implementation, radiation dose reduction and further development of new image reconstruction algorithms and image post processing tools, such as CT perfusion, CT spectral imaging and iterative reconstruction techniques.

The CT physics and technology research group focuses on the development and implementation of advanced image reconstruction and processing techniques with specific focus on improved patient diagnostics combined with reduced radiation dose. Future objectives include validation of new methodology, such as iterative image reconstruction, spectral imaging, CT organ perfusion, in terms of improved diagnostic outcome and socioeconomic value.

Projects:

  • Spectral imaging and iterative reconstruction in CT: Image quality and radiation doses
  • Optimization of diagnostic image quality and radiation dose of radiological tomography techniques using advanced post processing reconstruction algorithms
  • New method for liver metastasis diagnostics in patients with colorectal cancer (part of the Oslo Comet study)
  • Ultralow dose chest CT vs conventional chest X-ray
  • HyPerCept – Color and Quality in higher dimensions: Optimizing visual and diagnostic image quality in radiography. In collaboration with NTNU Gjøvik
  • CT image quality test methodology
