Abstract
In one embodiment, an MRI apparatus () includes a gap calculating unit (), a candidate calculating unit () and a sequence setting unit (). The gap calculating unit calculates a gap between the center frequency of an RF pulse and a resonance center frequency, after start of a pulse sequence. The candidate calculating unit calculates a plurality of candidate timings so as to avoid influence of a CF scan for measuring the resonance center frequency on MR signals, when the CF scan is inserted in the pulse sequence. The sequence setting unit sets the pulse sequence so that CF scans are inserted in the pulse sequence at the timings according to the gap and the candidate timings. Each time the CF scan is executed, the center frequency of an RF pulse is updated and the pulse sequence is continued. Thereby, the MR signals are acquired.
