MAGNETIC RESONANCE IMAGING DEVICE AND GRADIENT MAGNETIC FIELD CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging device or the like capable of reducing artifacts independent of photographing conditions. SOLUTION: A polarity relating to the gradient of a gradient magnetic field inclined along a first direction and composited with a static magnetic field generated by a magnet is selected corresponding to a photographing position. To put it concretely, the polarity of the gradient magnetic field Gs is controlled such that the polarity of the photographing position relating to the first direction and the polarity of the gradient magnetic field at the photographing position become opposite.
