1. A method for magnetic resonance imaging, comprising: providing a first sampling mask for sampling along a first set of parallel lines extending in a first direction in k-space; providing a second sampling mask for sampling along a second set of parallel lines extending in a second direction in k-space, where the second direction is orthogonal to the first direction; sampling a first set of magnetic resonance (MR) k-space data using an MR scanner by scanning a subject in the first direction using the first sampling mask; sampling a second set of MR k-space data using the MR scanner by scanning the subject in the second direction using the second sampling mask; and reconstructing an MR image from a combined set of MR k-space data including the first set of MR k-space data and the second set of MR k-space data.
