Abstract:
A method of magnetic resonance comprising:exciting and manipulating magnetic resonance in a subject by using temporally interleaved non-commuting radio frequency pulses and their inverses, including applying a first radio frequency pulse temporally commensurate with a first slab select gradient, to define a first excited slab within the subject; applying a second radio frequency pulse temporally commensurate with a second slab select gradient, different from the first gradient, to define a second excited slab intersecting the first excited slab applying an inverse of the first radio frequency pulse temporally commensurate with a repetition of the first slab select gradient; applying an inverse of the second radio frequency pulse temporally commensurate with a repetition of the second slab select gradient to yield a net excitation in an intersection of the first and second slabs and substantially no excitation outside of the intersection; applying at least two different gradient fields with the radio frequency pulses.
