CT physics and technology

A.C.T. Martinsen
Group leader

The 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.
