Time-of-flight (ToF) cameras have the potential to deliver real-time position information for prospective motion correction without special optical markers like retro-reflective spheres, checkerboard patterns or Moir markers. In this abstract, we are reporting our initial experiments with a ToF camera within the bore of a 7T MR scanner. The modifications to make the camera MR-compatible as well as residual challenges are described and discussed.
