A medical information processing apparatus according to an embodiment includes processing circuitry. The processing circuitry calculates noise intensity from first data acquired during a first scan. The processing circuitry calculates a denoising intensity used for a denoising process based on the noise intensity and the difference between an imaging condition for the first scan and an imaging condition for a second scan, the denoising process being applied to second data obtained by the second scan.

Medical information processing apparatus and medical information processing method

A magnetic resonance imaging apparatus includes processing circuitry. The processing circuitry is configured to acquire a first coil sensitivity map and a second coil sensitivity map for a plurality of coils, the second coil sensitivity map being different in phase from the first coil sensitivity map; generate a first image based on the first coil sensitivity map and magnetic resonance data related to the plurality of coils; generate a second image based on the first coil sensitivity map, the second coil sensitivity map, and the first image; and generate a final image from the first image and the second image.

Magnetic resonance imaging apparatus, image generation method, and computer-readable nonvolatile storage medium storing image generation program

An image generating apparatus according to an embodiment includes processing circuitry. The processing circuitry obtains a coil sensitivity distribution indicating a sensitivity distribution of a reception coil used for an imaging process performed on an examined subject and magnetic resonance data acquired from the imaging process that is non-Cartesian and performed in a k-space. The processing circuitry performs, on the basis of the coil sensitivity distribution, registration between the coil sensitivity distribution and a gridding sensitivity distribution indicating a distribution of gridding sensitivity related to arranging the magnetic resonance data in the k-space. The processing circuitry generates a magnetic resonance image on the basis of a result of the registration, magnetic resonance data, coil sensitivity distribution, and gridding sensitivity distribution.
