摘　　要：目的在标准立体定向空间应用《中国数字化可视化人体图谱》男性尸脑切片构建豆状核亚结构一苍白球内侧部（Gpi）数字化图谱。方法对数字化可视化人体图谱尸脑切片解剖学图像进行Gpi及前连合、后连合的识别与分割等处理，并应用软件对处理后的Crpi进行三维重建，并建立立体定向坐标系。结果三维重建的Gpi为近似蚕豆状的灰质团块，同时构建了壳核及苍白球外侧部（Gpe），图谱能够清晰的显示三者在立体定向空间的位置关系。三维可视化的效果为豆状核可以在立体定向空间任意角度的旋转、缩放。结论利用超薄尸脑解剖图像可以在标准立体定向空间成功对颅内神经结构亚核团进行三维重建。Objective To construct a digital atlas of the globus pallidus internus （Gpi） in the standard stereotactic space using the sectional images of the male cadaver from ＂Atlas of Chinese Visible Human （Male and Female）＂. Methods Identification and segmentation of the Gpi, and anterior and posterior commissures from the sectional images were performed. We established the stereotactic coordinate system and reconstructed 3D models of the Gpi. Results Gpi looks like a bean according to the reconstructed models; Putamen and globus pallidus lateral （Gpe） were also constructed; and the location of the Gpi and the relation of Gpi with both Putamen and Gpe were shown in the stereotactic space. The lenticular nucleus could rotate and stretch at any angles in the standard stereotactic space. Conclusion It is feasible to reconstruct the 3D models of the subnucleus in the stereotactic space from the sectional image of the cadaver.
