Abstract: A magnetic resonance imaging apparatus includes a setting unit which sets a section position, a first image creating unit which creates a first image at the set section position by a multi planar reformat on the basis of a magnetic resonance signal collected from a subject by a first imaging sequence at a 3D region or multiple section positions different from the set section position, a determining unit which determines a section position of the first image, and a second image creating unit which creates a second image at the determined section position by the multi planar reformat on the basis of a magnetic resonance signal collected from the subject by a second imaging sequence different from the first imaging sequence at a 3D region or multiple section positions different from the determined section position.

Abstract: A apparatus includes a collection unit which collects a magnetic resonance signal, a unit which controls the collection unit in such a manner that pre-scan is executed in regard to pre-scan slices determined as some of main scan slices, a calculation unit which calculates correction amounts based on data concerning the pre-scan slices obtained by the pre-scan, an estimation unit which estimates a correction amount concerning each slice other the pre-scan slices in the main scan slices based on the correction amounts, and a unit which controls the collection unit in such a manner that each of the main scan slices is scanned while involving correction of each slice that is the pre-scan target with the correction amount thereof calculated by the calculation unit and while involving correction of each slice that is not the pre-scan target with the correction amount thereof estimated by the estimation unit.

Abstract: A magnetic resonance imaging apparatus includes an acquisition unit, a calculation unit, a recalculation unit, a correction unit and a generating unit. The acquisition unit acquires data from plural slices in an object by rotating a zonary region in frequency space by every repetition time. The calculation unit calculates correction parameters for motion correction. The recalculation unit recalculates at least a part of the correction parameters based on relationship between values of the correction parameters and at least one of real-spatial positions and times at which the data is acquired. The correction unit corrects the data using correction parameters including recalculated correction parameters. The generating unit generates image data based on corrected data.
