Abstract: Embodiments of the present invention disclose a magnetic resonance system, a magnetic resonance image correction method, and a magnetic resonance imaging method. The magnetic resonance image correction method comprises: separately obtaining main magnetic field intensity distribution information and gradient magnetic field information of a magnetic resonance system, the gradient magnetic field information comprising one or more among X-axis gradient magnetic field information, Y-axis gradient magnetic field information, and Z-axis gradient magnetic field information; obtaining a first correction coefficient based on the main magnetic field intensity distribution information; obtaining, based on one or more among the X-axis gradient magnetic field information, the Y-axis gradient magnetic field information, and the Z-axis gradient magnetic field information, one or more corresponding second correction coefficients; and, correcting image data obtained by means of the magnetic resonance system based on the first correction coefficient and the one or more second correction coefficients.
