Disclosed is a three-dimensional parallel image reconstruction scheme and system using a boomerang-shaped kernel. A three-dimensional parallel image reconstruction scheme according to an embodiment ofthe present invention comprises the steps of: (a) acquiring MRI scanning data including a plurality of missing data and a plurality of acquired data for a subject; (b) filling the plurality of missing data with estimation data values calculated on the basis of the plurality of acquired data on a k-space; and (c) reconstructing the MRI scanning data on the k-space, which is filled with the estimation data values, as an MRI image, wherein step (b) is performed using a boomerang-shaped kernel. 本发明公开种使用回旋镖形状的内核的三维并行图像重建方法及系统。根据本发明的实施例的三维并行图像重建方法包括以下步骤：(a)对被检体获取包含多个获取数据(acquired data)和多个未获取数据(missing data)的MRI扫描数据；(b)在k空间上利用以所述多个获取数据为基础运算出的推算数据值来填补所述多个未获取数据；以及(c)将填补所述推算数据值后的所述k空间上的MRI扫描数据重建为MRI图像，所述(b)步骤通过使用回旋镖形状的内核(boomerang-shaped Kernel)来执行。
