Abstract:
In order to improve contrast 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 is a fan shape having the radius and the arc of a circle centered on the origin of a k space. At this time, echo signal arrangement is controlled such that an echo signal for desired TE of each fan-shaped blade is arranged in a low spatial frequency region of the k space.
