AB  - PURPOSE: We suggest a motion correction concept that employs free-induction-decay 
      (FID) navigator signals to continuously monitor motion and to guide the 
      acquisition of image navigators for prospective motion correction following 
      motion detection. METHODS: Motion causes out-of-range signal changes in FID time 
      series that, and in this approach, initiate the acquisition of an image 
      navigator. Co-registration of the image navigator to a reference provides 
      rigid-body-motion parameters to facilitate prospective motion correction. Both 
      FID and image navigator are integrated into a prototype magnetization-prepared 
      rapid gradient-echo (MPRAGE) sequence. The performance of the method is 
      investigated using image quality metrics and the consistency of brain volume 
      measurements. RESULTS: Ten healthy subjects were scanned (a) while performing 
      head movements (nodding, shaking, and moving in z-direction) and (b) to assess 
      the co-registration performance. Mean absolute errors of 0.27 +/- 0.38 mm and 
      0.19 +/- 0.24 degrees  for translation and rotation parameters were measured. Image quality 
      was qualitatively improved after correction. Significant improvements were 
      observed in automated image quality measures and for most quantitative brain 
      volume computations after correction. CONCLUSION: The presented method provides 
      high sensitivity to detect head motion while minimizing the time invested in 
      acquiring navigator images. Limits of this implementation arise from temporal 
      resolution to detect motion, false-positive alarms, and registration accuracy.
