Abstract
In order to improve contrast and image quality in non-orthogonal measurement without sacrificing speed, in imaging which combines a fast imaging sequence for acquiring a plurality of echo signals in one shot with non-orthogonal system measurement, the shape of a blade in which an echo train of each shot is arranged includes a fan-shaped region having the radius and the arc 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 an echo signal for desired TE of each blade is arranged in a low spatial frequency region of a k space, and during image reconstruction, body motion between the blades is corrected using data of the overlapping regions.
