A method for magnetic resonance imaging (MRI) a first volume and a second
volume spaced apart from the first volume is provided. The first volume
is excited with a first linearly varying phase with respect to k-space.
The second volume is excited with a second linearly varying phase with
respect to k-space, wherein the first linearly varying phase has a
different slope than the second linearly varying phase. Data in k-space
is acquired line by line. The acquired data in k-space is Fourier
transformed to image space. An image is formed with a first volume image
and a second volume image from the transformed data. Use of phase
modulation allows imaging with a reduced field-of-view, which can result
in faster scan times or improved performance of parallel imaging
acquisition strategies.
