Zusammenfassung:	To provide a magnetic resonance imaging apparatus capable of improving image quality of a magnetic resonance image.SOLUTION: A magnetic resonance imaging apparatus includes a determination part, a collection part, a constitution part, and an adjustment part. The determination part determines a cross-sectional position according to a three-dimensional static magnetic field distribution (S203). The collection part collects a resonance frequency distribution at the cross-sectional position (S204). A calibration part coordinates the resonance frequency distribution with the three-dimensional static magnetic field distribution (S205). The adjustment part adjusts center frequency in image capturing at a subsequent stage on the basis of the coordinated three-dimensional static magnetic field distribution (S206).SELECTED DRAWING: Figure 2 【課題】磁気共鳴画像の画質を向上させることのできる磁気共鳴イメージング装置を提供する。【解決手段】磁気共鳴イメージング装置は、決定部と、収集部と、構成部と、調整部とを含む。決定部は、３次元の静磁場分布から断面位置を決定するＳ２０３。収集部は、断面位置における共鳴周波数分布を収集するＳ２０４。較正部は、共鳴周波数分布と３次元の静磁場分布とを対応付けるＳ２０５。調整部は、対応付けられた３次元の静磁場分布に基づき、後段の撮像における中心周波数を調整するＳ２０６。【選択図】図２
