本工作报告使用扩散张量磁共振纤维束成像可视化的三维（3D）结构的主要白色物质束内生活的人类大脑。具体来说，我们应用这种技术在体内可视化（i）上级纵（弓）束，（ii）下纵束，（iii）上级额枕神经束，（胼胝体下）束，（iv）额枕下束，（v）钩束，（vi）扣带，（vii）前连合，（viii）胼胝体，（ix）内囊，和（x）穹窿。这些纤维束首先被分离出来，然后交互式地显示为3D渲染对象。使用这种方法在体内获得的虚拟道地图是忠实的经典描述的白色物质解剖，以前已经记录在死后的研究。由于我们已经能够交互式地描绘和可视化白色物质束在其整个长度在体内，以一种方式，以前只可能通过组织学手段，“虚拟在体内交互式解剖”（VIVID）增加了一个新的层面，解剖描述的活人脑。(C)2002 Elsevier Science（美国）。
This work reports the use of diffusion tensor magnetic resonance tractography to visualize the three-dimensional (3D) structure of the major white matter fasciculi within living human brain. Specifically, we applied this technique to visualize in vivo (i) the superior longitudinal (arcuate) fasciculus, (ii) the inferior longitudinal fasciculus, (iii) the superior fronto-occipital (subcallosal) fasciculus, (iv) the inferior fronto-occipital fasciculus, (v) the uncinate fasciculus, (vi) the cingulum, (vii) the anterior commissure, (viii) the corpus callosum, (ix) the internal capsule, and (x) the fornix. These fasciculi were first isolated and were then interactively displayed as a 3D-rendered object. The virtual tract maps obtained in vivo using this approach were faithful to the classical descriptions of white matter anatomy that have previously been documented in postmortem studies. Since we have been able to interactively delineate and visualize white matter fasciculi over their entire length in vivo, in a manner that has only previously been possible by histological means, "virtual in vivo interactive dissection" (VIVID) adds a new dimension to anatomical descriptions of the living human brain.
