虚拟中国人女Ⅰ号(VCH-FⅠ)臂丛神经可视化初步研究

Visualization of anatomic structures of the normal brachial plexus of the VCH Female I

目的观测“虚拟中国人”(VirtualChineseHuman,VCH)Ⅰ号女性臂丛神经连续横断面的走行,建立臂丛神经的可视化数字模型。方法应用虚拟中国人女Ⅰ号(VCH-FⅠ)数据集,在颈部薄层断面图像上观察臂丛神经与椎管、脊髓、横突孔、椎动脉等结构,应用Amira3.1(TGS)软件对臂丛神经进行计算机三维重建并立体显示。结果在VCH-FⅠ的颈部薄层断面图像上清楚地显示了臂丛神经以及颈段其它的结构,重建的数字化模型可准确的反映臂丛神经的解剖学结构特点。结论VCH-FⅠ数据集能够提供完整精确的臂丛神经解剖,为臂丛神经损伤的影像诊断和外科治疗提供了良好的形态学依据。

Objective To observe and establish the digitized visible model of normal structures of the braehial plexus of the Virtual Chinese Human （VCH） Female Ⅰ . Methods Cross-sectional images of fresh tissues from the female Chinese visible human dataset were reviewed and the structures of the normal brachial plexus were confirmed on a section-by-section basis. The vertebral canal, spinal cord and vertebral artery were also observed. Three-dimensional computerized reconstructions of the brachial plexus and its adjacent structures were generated from these data using Amira 3.1 （TGS） imaging software. Results The cross-sectional images of the VCH Female Ⅰ could fairly display the main structures of the brachial plexus, and also demonstrate osseous tissues, connective tissues, nerves and vessels, The three-dimensional reconstructed images could display perfectly the anatomic relationships of these structures. Conclusion The VCH Female Ⅰ dataset can provide complete and accurate data of main structures of the brachial plexus, The digitized model of brachial plexus offers unique insights into the complex anatomy, providing morphologic data for imaging diagnosis and treatment of injuries of the brachial plexus.
