MRI hardware development
To develop electronic devices, the Department of Neurophysics is equipped with a modern electronics laboratory. The main aim is to develop devices suitable for use in MRI scanners. This means they should be completely non-magnetic, cause minimal interference with the MR imaging and must withstand the forces of 7 Tesla MRI. The development process encompasses all stages from conception to the production of prototypes, in accordance with the directives of German medical product laws.
When completed, the prototypes can be used during scanning of human subjects. Currently, two projects are under development; A response box and a tracking system. The response box will be used to measure reaction times during visual or auditory stimulation. The tracking system will detect a subject's movements and compensate for these by adjusting imaging gradients during image acquisition. The photograph shows the set up of an experiment with the tracking system.
