Method and system to perform phase correction for species separation in magnetic resonance imaging

A magnetic resonance imaging system, comprising:

• a scanner, comprising:
• a primary magnet coil;
• a set of gradient coils;
• and
• a RF coil;
• scanner control circuitry capable of controlling operation of the scanner, the scanner control circuitry comprising:
• a memory capable of storing a first pulse sequence and a second pulse sequence;
• control circuitry capable of implementing the first and the second pulse sequence using the primary magnet coil, the set of gradient coils, and the RF coil, wherein the first pulse sequence, when executed, generates a first set of lines of imaging signals having a first read-out gradient and wherein the second pulse sequence, when executed, generates a second set of lines of imaging signals having a second read-out gradient that has reversed polarity with respect to the first read-out gradient;
• and
• system control circuitry capable of controlling operation of the scanner control circuitry.

A computer-readable medium physically encoding one or more routines comprising:

• a routine capable of acquiring first and second sets of lines of magnetic resonance imaging signals, wherein the first and second sets of lines have read-out gradient polarities that are opposite to one another;
• a routine capable of determining a two-dimensional phase error using the first and second sets of lines;
• a routine capable of recovering an intrinsic signal after correcting for the two-dimensional phase error;
• and
• a routine capable of generating one or more species specific images using the intrinsic signal.
