Abstract
A magnetic resonance imaging apparatus according to an embodiment includes: an obtaining unit, a correction coefficient deriving unit, an amplification degree deriving unit, and a filtering processing unit. The obtaining unit obtains a distribution of a radio frequency magnetic field. The correction coefficient deriving unit derives, on a basis of the distribution of the radio frequency magnetic field, a transmission correction coefficient used for correcting a transmission unevenness. The amplification degree deriving unit derives, for each of pixels, an amplification degree by which noise components are amplified in the image due to the correction, on the basis of either the distribution of the radio frequency magnetic field or the transmission correction coefficient. The filtering processing unit performs a filtering process according to the amplification degree on each of the pixels in the image to which the correction is applied.
