FIGURE 5.

Estimated rotational motion during imaging of a volunteer performing five different motion patterns (columns). The acquisitions were repeated with PMC on and off. To achieve repeatable motion patterns, videos of moving cross‐hairs were displayed on a screen behind the bore that the subject could observe through a mirror. This resulted in highly synchronous motion between repeated acquisitions, but with slight variations in offset and amplitude. The performed motion had a range of about 10° rotation
