1. A method of imaging large volumes without resulting slab-boundary artifacts comprising: defining a desired FOV larger than an optimal imaging volume of an MR scanner; selecting a slab thickness in a first direction that is smaller than the desired FOV and within the optimal imaging volume of the MR scanner; exciting and encoding spins to acquire data that is restricted to the selected slab thickness; acquiring MR data that includes acquiring full encoding data in the first direction for a subset of another two directions; step-wise moving one of the optimal imaging volume and an imaging object; and acquiring another set of MR data between each step-wise movement until the desired FOV is imaged.
