Travelling wave MRI has been tested for safety aspects for its application to human head imaging by means of full wave simulations including anatomical tissue models. It could be shown, that such a setup can be safely used within the same power limitations as volume head coils. Based on that, initial experiments revealing the RF coverage achieved by travelling wave MRI have been performed. The scans showed, that covering the head including the shoulders is feasible. In order to cope with present non-uniformities, an initial approach to match dielectric interfaces reducing reflections has been evaluated.
