Abstract: According to one embodiment, a magnetic resonance imaging apparatus includes processing circuitry. The processing circuitry estimates transmission inhomogeneity caused in a transmit RF magnetic field from a first image based on a first signal received by a whole-body coil, and estimates reception inhomogeneity caused in a receive RF magnetic field from the first image and a second image based on a second signal received by a surface coil. The processing circuitry generates a third image, having a resolution higher than a resolution of the first image and a resolution of the second image, based on a third signal received by the surface coil. The processing circuitry corrects the third image by using the estimated transmission inhomogeneity and reception inhomogeneity.
