Abstract:
1. A magnetic resonance imaging apparatus that acquires an image of each slice of an object on the basis of magnetic resonance signals measured from a plurality of slices of the object arranged in a static magnetic field, the apparatus comprising: a data collection unit that collects a magnetic resonance signal corresponding to each specific region amongst a plurality of specific regions, as specific region data, by rotating a specific region, which includes an origin of k space and a vicinity of the origin, around the origin; a data correction unit that corrects the specific region data to generate corrected specific region data; and an image reconstruction unit that reconstructs an image from the corrected specific region data, wherein the data correction unit sets one of the plurality of slices as a benchmark slice, detects body movement of the object, which occurs between measurement of a reference specific region as a reference of the plurality of specific regions and measurement of other specific regions excluding the reference specific region, in the benchmark slice, corrects specific region data of the other specific regions in all slices so as to eliminate an influence of the detected body movement on an image, and sets specific region data of the reference specific region and specific region data after correction of the other specific regions as the corrected specific region data in each slice, wherein the data correction unit includes a benchmark slice determination unit that determines the benchmark slice, and the benchmark slice determination unit determines a slice of which a predetermined feature amount is maximum or minimum, among all slices, as the benchmark slice.
