Summary:In order to improve image quality and contrast without sacrificing speed in non-orthogonal measurement, imaging in this magnetic resonance imaging device combines non-orthogonal measurement with high-speed imaging sequences in which multiple echo signals are acquired with one shot, wherein the shape of the blade in which the echo train of each shot is arranging has a wedge region configured from a circular arc and the radius of a circle centered on the origin of the k-space, and a region overlapping an adjacent blade. During measurement, control is performed such that a desired TE echo signal is arranged, for each blade, in the low spatial frequency region of the k-space, and during image reconstruction, body motion between the blades is corrected using data of the overlapping regions.
