Abstract:
An offset map is determined in advance by a preliminary measurement process. A phase map is generated by execution of a long τ pulse sequence. A magnetic field map is calculated based on a phase map and a phase offset map. A shim adjustment is performed based on the magnetic field map. The offset map is calculated based on a first phase map acquired by execution of a first pulse sequence, a second phase map acquired by execution of a second pulse sequence, and a ratio α related to phase evolution periods.

Claim (Index 5):
The nuclear magnetic resonance measurement apparatus according to  claim 4 , wherein\n the phase offset map calculator comprises: an acquirer that acquires a positive-side first phase map and a positive-side second phase map by preliminarily executing the first pulse sequence and the second pulse sequence in a state where a value of a particular shim coefficient is changed in a positive side, and that acquires a negative-side first phase map and a negative-side second phase map by preliminarily executing the first pulse sequence and the second pulse sequence in a state where the value of the particular shim coefficient is changed in a negative side; and a ratio calculator that calculates the ratio \u03b1 based on the positive-side first phase map, the positive-side second phase map, the negative-side first phase map, and the negative-side second phase map.
