Spatial encoding mr data of a moving subject using a higher-order gradient field

摘要

The present invention includes a technique for use with magnetic resonance imaging that includes the application of a non-linear, higher-order gradient field (126) in the presence of a moving object (122) 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 lonsitudinal direction of the moving object.
