Abstract:

We developed a novel force display device, which can be used for functional magnetic resonance imaging (fMRI) studies in order to investigate brain functions and reparative plasticity in the sensorimotor cortex. The challenge was to provide a large torque, whereas the interference between the magnetic fields of the MR-scanner and the device should affect neither image quality nor the device function. The device was tested in a 3T MRscanner. With a current of up to 1A and a distance of 1m to the focal point of the MR-scanner it was possible to generate torques of up to 4 Nm. Within these boundaries image quality was not affected.
