摘　　要：收集水样品到静磁场和射频磁场作用后 ,每一个自由感应衰减信号 ,并对其进行三维傅立叶变换 ,建立一个数据矩阵 ,矩阵的每个矩阵元由对应的氢原子图像像素决定。First survey the effect of the static electromagnectic field and the radio-frequency eletromagnetic field to the sample of water,then collect all of the free reaction attenuation signal making it three-dimensional Fourier transformed,the data matrix can be formed and the picture element data corre sponding every dot of the matrix form a picture.

关 键 词：氢原子图像 三维傅立叶变换 磁共振成像 图像矩阵 像素 三维重建
