【摘要】：目的探讨数字人脑中伏隔核的定位、参数测量及三维显示。方法运用数控铣床完成1例45岁男性标本头部原始数据的采集,断面间距0.5mm。选取包含脑组织的连续横断面图像300幅,利用Photoshop CS软件完成尾状核、壳、伏隔核的图像分割,在重建的连续冠状断面图像上按照哈佛大学医学院的颅脑图像分割方法区分伏隔核,计算伏隔核体积及相关位置信息。利用Amira 3.1.1软件实现尾状核、壳、伏隔核的三维可视化。结果伏隔核及其毗邻结构、常用伏隔核损毁靶点清晰显示。伏隔核体积左侧为972.5mm3,右侧为830.6mm3,左侧大于右侧。伏隔核质心三维坐标,左侧(-11.0,24.4,1.3),右侧(9.3,23.9,1.7)。结论伏隔核的数字解剖能够清晰显示伏隔核的形态,明确伏隔核的体积、位置及毗邻关系。
[Abstract]:Objective to study the location, parameter measurement and 3D display of nucleus accumbens in digital human brain. The sectional spacing was 0.5 mm. 300 consecutive cross-sectional images including brain tissue were selected and the images of caudate nucleus, shell and nucleus accumbens were segmented by Photoshop CS software. The nucleus accumbens was distinguished on the reconstructed continuous coronal sectional images according to the brain image segmentation method of Harvard University Medical School. The volume and location information of nucleus accumbens were calculated. The three-dimensional visualization of caudate nucleus, shell and nucleus accumbens was realized by using Amira 3.1.1 software. Results the nucleus accumbens and its adjacent structures were obtained. The volume of nucleus accumbens was 972.5mm 3 on the left side and 830.6mm 3 on the right side. The mass center of nucleus accumbens was larger on the left side than on the right side, and the left side was -11.0. Conclusion the digital anatomy of nucleus accumbens can clearly show the shape of nucleus accumbens and determine the volume, location and adjacent relationship of nucleus accumbens.

【正文快照】： 伏隔核(nucleus accumbens)也称伏核,位于内囊前肢的腹侧,尾状核、壳的前下方,在中脑边缘多巴胺系统中居核心地位。研究表明,该核团与药物成瘾及人的心理行为紧密相关[1~5]。我们利用数字解剖学手段,对该核团的位置、体积、形态进行系统研究,为临床应用提供解剖学依据。材料和
