A method and apparatus for single carrier wideband magnetic resonance imaging (MRI) data acquisition are provided. The method includes the following steps: exciting a slice or slab with the use of RF pulse and a slice/slab selection gradient; applying a phase encoding gradient along a phase encoding direction and reducing a FOV along the phase encoding direction by a factor of W through k-space subsampling; applying a frequency encoding gradient along a frequency encoding direction and increasing a FOV along the frequency encoding direction by a factor of W; and applying a separation gradient along the phase encoding direction during the frequency encoding duration and k-space data acquisition.

Method and apparatus for single carrier wideband magnetic resonance imaging (MRI) data acquisition

The present invention discloses a 3-dimension magnetic resonance imaging method which comprises: applying a slab selection gradient to a subject; transmitting a radiofrequency pulse to the subject, and exciting a slab of the subject to produce magnetic resonance signals with a continuous frequency bandwidth; performing a spatial encoding gradient across three dimensions to encode the magnetic resonance signals, wherein an equivalent encoded field of view which along the selected acceleration direction is controlled by the spatial encoding gradient, and the equivalent encoded field of view is shorter than the excited slab size of the subject; applying a separation gradient along with the spatial encoding gradient; and receiving and reconstructing the encoded magnetic resonance signals to produce 3D images.
