The present invention includes a technique for use with magnetic resonance
imaging that includes the application of a non-linear, higher-order
gradient field in the presence of a moving object to be scanned. MR data
is acquired as the object moves through the non-linear gradient field.
Resulting images are contiguous and do not require the patching together
of data in either k-space or image space and result in an image with
expanded FOV in a longitudinal direction of the moving object.
