| description | To provide a magnetic resonance imaging apparatus capable of improving quality of a magnetic resonance image.SOLUTION: A magnetic resonance imaging apparatus includes a calculation unit, a collection unit, and a correction unit. The calculation unit calculates a static magnetic field correction amount on the basis of static magnetic field distribution in a second imaging range narrower than a first imaging range (S204). The collection unit collects MR images in the first imaging range under the static magnetic field corrected on the basis of the static magnetic field correction amount (S206). The correction unit corrects distortion in the collected MR images (S207).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、算出部と、収集部と、補正部とを含む。算出部は、第１撮像範囲よりも狭い第２撮像範囲の静磁場分布に基づいて静磁場補正量を算出するＳ２０４。収集部は、静磁場補正量に基づき補正された静磁場の下で、第１撮像範囲のＭＲ画像を収集するＳ２０６。補正部は、収集されたＭＲ画像の歪みを補正するＳ２０７。【選択図】図２ |
