Abstract :
When shifting the FOV during imaging, artifacts arise when the shift per volume encoding time is larger than the resolution. Up to shift velocities of about 1 m/s, these can be removed by compensating the system function for the rapid translation. Fast continuous FOV shifts may be used to rapidly steer a single imaging volume to a region of interest or to achieve large spatial coverage by repeatedly sweeping the FOV through a volume of interest.
