Claim:
1. A magnetic resonance imaging apparatus which collects echo signals generated by applying a high-frequency magnetic field and a gradient magnetic field to an object to be examined, which has been placed in a static magnetic field, in accordance with a predetermined pulse sequence and reconstructs an image from the collected echo signals, comprising: an adjustment unit configured to adjust a profile of an excitation region to be excited by a local excitation sequence, the adjustment unit using (a) a profile adjustment value of the local excitation sequence and (b) a profile adjustment value table in which profile parameters associated with corresponding adjustment values of the local excitation sequence for exciting the excitation region to obtain a specific profile are stored, a profile adjustment value calculating unit configured to calculate the profile adjustment value of the local excitation sequence, for exciting the excitation region to have an excitation region profile specified by an operator, and a determination unit configured to determine whether or not a corresponding adjustment value associated with a combination of the profile parameters corresponding to the excitation region profile specified by the operator is stored in the profile adjustment value table, wherein the profile adjustment value calculating unit calculates the profile adjustment value of the local excitation sequence when the determination unit determines that the corresponding adjustment value associated with the profile parameters corresponding to the excitation region profile specified by the operator is not stored in the profile adjustment value table.
