虽然傅立叶梯度相位编码和Hadamard射频编码是两种已建立的空间MR定位技术,但后者缺乏体素移位和插值后处理算法,一直使其处于令人沮丧的劣势。本文提出了一种用于Hadamard编码数据的体素移位和插值的方法,并从理论和实验上证明了这两种定位方法之间各自操作的相似性。
While Fourier gradient phase-encoding and Hadamard radio-frequency encoding are two established spatial MR localization techniques, the absence of voxel-shift and interpolation post-processing algorithms for the latter has always placed it at a discouraging disadvantage. This paper presents a method for voxel-shift and interpolation of Hadamard-encoded data and demonstrates both theoretically and experimentally the similarities of the respective operations between the two localization methods.
