Methods for obtaining MRI frequency maps
Abstract:
A magnetic resonance imaging (MRI) method includes generating first and second spin populations within each of a plurality of pixels of a slice of an object. These spin populations have different phase histories. For each pixel, MRI signals from those spin populations are acquired at different times These MRI signals can then be used to determine a field strength difference between different pixels of the slice.
