The subject invention pertains to method and apparatus for parallel
imaging. The subject method can be utilized with imaging systems
utilizing parallel imaging techniques. In a specific embodiment, the
subject invention can be used in magnetic resonance imaging (MRI). A
specific embodiment of the subject invention can reduce parallel
reconstruction CPU and system resources usage by reducing the number of
channels employed in the parallel reconstruction from the M channel
signals to a lower number of channel signals. In a specific embodiment,
sensitivity map information can be used in the selection of the M channel
signals to be used, and how the selected channel signals are to be
combined, to create the output channel signals. In an embodiment, for a
given set of radio-frequency (RF) elements, an optimal choice of
reconstructed channel modes can be made using prior view information
and/or sensitivity data for the given slice. The subject invention can
utilize parallel imaging speed up in multiple directions.
