Up to now, no sufficient experimental data about the exposure especially to movements in the stray field of MR systems are available. In this study the neurobehavioral effects is measured during the exposure to static fields and during controlled movements in the stray fields of different field strength. For this purpose we designed a magnetic field dosimeter, a motion system, a 7T compatible presentation tool, and a 0T MR system for control measurements. It could be shown that the experimental design is suitable for this complex study. First results show no significant effects on the exposure to static magnetic fields.
