PROBLEM TO BE SOLVED: To diminish a phase shift of a spin caused by an eddy current and the spin movement generated by receiving a phase encoding pulse of SSFP (Steady-State Free Precession) sequence.SOLUTION: A (k) space is divided into a plurality of small areas in the circumferential direction of an ellipse around a radial vector related to the center point in the (k) space and the center point in such a manner that each small area includes the same number of lattice points, and the signal collection is so scheduled that targeting lattice points for collecting magnetic resonance signals by a series of high frequency excitation are defined as the lattice points which are selected one each from small areas aligned in the radial vector out of the plurality of small areas.COPYRIGHT: (C)2008,JPO&INPIT【課題】 渦電流やスピンの動きがSSFPシーケンスの位相エンコードパルスを受けて発生させるスピンの位相シフトを小さくする。【解決手段】 格子点をほぼ同数ずつ含むようにk空間をk空間内の中心点に関する動径方向および中心点を中心とした楕円の円周方向に分割して複数の小領域を定め、一連の高周波励起により磁気共鳴信号を収集する対象の格子点を、複数の小領域のうちで動径方向に並んだ小領域からそれぞれ1つずつ選んだ格子点とするように信号収集をスケジューリングした。【選択図】 図3
