Center for Magnetic Resonance has employed Fróði Gregersen as PhD student.
Fróði Gregersen will work on the project Mapping of current-induced magnetic fields in the human brain using ultrahigh field magnetic resonance imaging.
The project is a collaboration between CMR at DTU, Copenhagen University Hospital Hvidovre and the State Key Laboratory of Brain and Cognitive Sciences, Institute of Biophysics, Beijing. The project is funded by Sino-Danish Center for Education and Research (SDC) and DTU.
The project aims to map the conductivity of brain tissue by measuring weak current-induced fields in the brain using a 7 tesla MR scanner. Recently, a novel method with very promising results was developed by the Danish project partners on a 3 tesla scanner. 7 tesla MR can double the signal strength and therefore improve the conductivity measurement, but also poses new challenges which will be the focal point of Fróði's PhD project.
Mapping the conductivity of the brain has many applications both clinically and in neuroscience research, such as making individualized head models to improve the accuracy of transcranial brain stimulation and electro- and magnetoencephalography.
Danish Supervisors are Associate Professors Lars G. Hanson and Axel Thielscher. As part of the conditions of the SDC grant, Fróði will spend 9 months at Institute of Biophysics in Beijing, under the co- supervision of Professor Rong Xue.
Fróði did his BSc in Electronics Engineering at DTU and holds an MSc in Neuroscience and Neuroimaging from SDC in China.
