Human white matter fiber crossings were investigated with use of the full eigenstructure of the magnetic resonance diffusion tensor. Intravoxel fiber dispersions were characterized by the plane spanned by the major and medium eigenvectors and depicted with three-dimensional graphics. This method improves the analysis of fiber orientations, beyond the principal fiber directions, to a broader range of complex fiber architectures.
利用磁共振扩散张量的全本征结构对人类白质纤维交叉进行了研究。体素内纤维离散度通过由主本征向量和中等本征向量所确定的平面来表征，并以三维图形呈现。该方法将纤维取向的分析从主要纤维方向扩展到更广泛的复杂纤维结构范围，超越了主要纤维方向。
