A magnetic resonance imaging apparatus according to an embodiment includes a processor and a memory. The memory stores processor-executable instructions that cause the processor to perform an application region scan for acquiring data on an area covering a diaphragm in order to position an application region of a motion detection pulse and a multi-slice scan for acquiring first multi-slice data on an area covering a heart; and acquire a slice image of the heart that is positioned using the first multi-slice data, with application of the motion detection pulse. In acquiring the slice image, when breathing motion of a subject is continuously out of an allowable range for a given period, the processor corrects a position of the application region by calculation using the second multi-slice data acquired by performing the multi-slice scan again and a positional relationship obtained by the application region scan and the multi-slice scan.

In one embodiment, an MRI apparatus () includes a reference scan setting unit (), a reference scan execution unit, and an image generation unit. The reference scan setting unit calculates a signal acquisition region of 'a reference scan in which MR signals used for generation of a sensitivity distribution map of each coil element are acquired', depending on an imaging region of a main scan of parallel imaging. The reference scan execution unit executes the reference scan on the calculated signal acquisition region. The image generation unit generates image data according to 'MR signals acquired by the main scan' and 'the sensitivity distribution map generated based on MR signals acquired by the reference scan'.

Magnetic resonance imaging apparatus and magnetic resonance imaging method

In one embodiment, a magnetic resonance imaging apparatus includes a magnetic resonance imaging apparatus includes: a gantry including at least an RF (Radio Frequency) coil and a gradient coil, wherein the RF coil receives MR (Magnetic Resonance) signals from an object when an RF signal from the RF coil and a gradient magnetic field from the gradient coil are applied to the object in a main scan; processing circuitry configured to reconstruct image data of a plurality of images of the object based on the MR signals, and generate display image data from the reconstructed image data, wherein the display image data is generated such that display images are observed from a unified observational direction, regardless of a case where cross-sectional directions vary; and a display configured to display the display images observed from the unified observational direction based on the display image data.
