    • PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging device capable of performing imaging with better image quality by an AFI method.SOLUTION: The magnetic resonance imaging device of an embodiment includes data collection means and image generation means. The data collection means collects a plurality of magnetic resonance signals corresponding to an asymmetric sampling area in the wave number direction in a k-space from a sample, in a data collection sequence having a first regularity and a data collection sequence having a second regularity different from the first regularity. The image generation means generates magnetic resonance image data by data processing including charging of a signal into a non-sampling area by using phase conjugate symmetry in the k-space, and image reconstruction processing on the basis of the plurality of magnetic resonance signals.
    • 要解决的问题:提供能够通过AFI方法执行具有更好图像质量的成像的磁共振成像装置。解决方案:实施例的磁共振成像装置包括数据采集装置和图像生成装置。 数据采集​​装置在具有第一规则性的数据采集序列和具有第二规则性不同的数据采集序列的情况下,从采样中收集与k个空间中的波数方向上的非对称采样区域相对应的多个磁共振信号 从第一个规律。 图像产生装置通过数据处理产生磁共振图像数据,包括通过在k空间中使用相位共轭对称性将信号充电到非采样区域中,并且基于多个磁共振信号进行图像重建处理。
