1. A method of measuring three-dimensional motion of an object by magnetic resonance imaging from one acquired image orientation, comprising: applying a magnetic resonance imaging pulse sequence to spatially modulate a region of interest of said object, the pulse sequence comprising a slice-following CSPAMM (complementary spatial modulation of magnetization) pulse sequence with added z-phase encode; acquiring a set of one or more vertically tagged images and a set of one or more horizontally tagged images of said spatially modulated object; and determining in-plane and through-plane motions of said spatially modulated object from the vertically and horizontally tagged images.
