Abstract: 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.

Abstract: An image generating apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to successively generate Magnetic Resonance (MR) images in a plurality of temporal phases by using a first reconstruction method. The processing circuitry is configured to determine a first temporal phase before MR images in all the temporal phases during a predetermined time period are generated. The processing circuitry is configured to generate an MR image in the first temporal phase determined by the determining unit, by using a second reconstruction method having a larger processing load than the first reconstruction method.

Abstract: A magnetic resonance imaging apparatus according to an embodiment includes processing circuitry. The processing circuitry generates a plurality of cross-sectional images for setting a sectional position to be collected in main imaging based on a characteristic portion of a target detected in three-dimensional data. The processing circuitry lists the cross-sectional images on a display and superimposes a mark corresponding to the characteristic portion on at least one of the cross-sectional images. The processing circuitry receives a setting operation to determine the sectional position. The processing circuitry causes, when the mark is selected in the setting operation, a cross-sectional image to be emphasized a sectional position of which is defined using the characteristic portion corresponding to the mark among the listed cross-sectional images. The processing circuitry performs main imaging based on the sectional position after the setting operation.
