摘要: In a magnetic resonance imaging apparatus and method for obtaining NMR navigator echoes with slight disturbance of the longitudinal magnetization, an EPI pulse sequence is generated to irradiate object be examined. Excitation which selective by means slice selection gradient, has small flip angle α<90° forms supplies signal read out in using phase encoding direction perpendicular direction. A spatially resolved rod obtained reconstructing column or row slice.
