Claim 0:
1. A magnetic resonance imaging apparatus comprising:
a measurement unit configured to receive a nuclear magnetic resonance signal generated in a subject by a receiving coil;
an image reconstruction unit configured to process the nuclear magnetic resonance signal received by the receiving coil and reconstruct an image of the subject;
an SNR spatial distribution calculation unit configured to calculate spatial distribution of noise of the image, calculate spatial distribution of the signal of the image, and calculate spatial distribution of a signal-to-noise ratio of the image using the spatial distribution of noise and the spatial distribution of the signal of the image;
a noise reduction unit configured to perform noise reduction to reduce noise from the image based on the spatial distribution of the signal-to-noise ratio; and
a noise processing unit configured to cause a reduced-noise image to be output, based on the noise reduction by the noise reduction unit.
