An improved method for computer-aided 3D reconstruction of neuroanatomical structures derived from intracranially fixed human brains is demonstrated. The embedded brains are cut into slices. The sliced surfaces are photographed. The outlines of the neuroanatomical structures are drawn onto transparencies which are scanned. The surfaces of the structures are 3D reconstructed with the triangulation method. The cortical structures of the human brain are complex, resulting in possible ambiguities for triangulation which must be solved interactively. These surface reconstructions allow for 3D visualization of the brain and its components comparable with intravital conditions found in clinical neuroimaging.
本文展示了一种改进的计算机辅助三维重建方法，用于从颅内固定的人脑获取神经解剖结构。将嵌入的大脑切成薄片，对切片表面进行拍照，把神经解剖结构的轮廓绘制在透明片上并进行扫描，然后采用三角测量法对结构表面进行三维重建。人类大脑的皮质结构复杂，这可能导致三角测量出现模糊性，必须通过交互式方式解决。这些表面重建能够实现大脑及其组成部分的三维可视化，可与临床神经成像中的活体状态相媲美。
