数字人体下肢筋膜重建经线与经络线形态学相似性的计算机化研究

目的利用计算机自动标识与三维重建技术,探索人体下肢筋膜类间隙结缔组织与经络经线形态位置相似性的证据及规律。方法获取虚拟中国人男1号(VCH-M1)数据集,截取左腿区域,利用计算机软件,首先提取肌肉信号,完成去噪处理;然后通过边缘检测,求出肌肉轮廓点的凸包;最后完成对间隙结缔组织的标记,并对标记的间隙结缔组织利用3D-Doctor软件进行三维重建。结果通过对虚拟人体下肢间隙结缔组织计算机自动识别标记,并对标记的间隙结缔组织进行三维重建,得到了与传统中医经络图谱描述相似的重建虚拟经线。结论本实验结果说明,南方医科大学人体解剖学教研室和中山大学科学计算与计算机应用研究所合作开发的将虚拟人体数据集应用于经络研究的计算机工具,可对虚拟人体下肢间隙结缔组织进行自动识别标记,并三维重建出虚拟筋膜经线,在一定程度上避免了筋膜重建手工识别过程中产生的人为因素误差,对于研究人体筋膜类间隙结缔组织与经络是否存在形态位置相关性有重要意义。

A DIGITAL STUDY ON THE MORPHOLOGIC COMPARABILITY BETWEEN MERIDIANS AND REBUILD FASCIA LINES IN THE VCH-MI'S LOWER LIMB

Objective To explore the evidence for the morphologic comparability between the meridians and interstitial connective tissues in the lower limb with auto-marked and 3D-Rebuilding technology. Methods First,the muscles were extracted and noise was eliminated;With edge detection a convex hull of the muscles edge was found;The interstitial connective tissue points were marked in the cross section images of left leg from the digital dataset of Virtual Chinese Human-Male1(VCH-M1).Finally,the auto-marked images were reconstructed with 3D-Doctor. Results The reconstructed meridians in the lower limb auto-marked with computer procedures tallied basically with the meridians and collaterals recorded in Traditional Chinese Medicine(TCM) illustrative graphics.Conclusion Having the advantages of digital anatomic study on acupuncture points earlier and mature 3D-Rebuilding techniques,the department of Anatomy of South Medical University cooperated with the Department of Scientific Calculation and Computer Application of Sun Yat-sen University to devise a set of computer programs which could be used to AutoMark interstitial connective tissues in Virtual Human lower limbs and then reconstruct virtual fascia meridians which corresponded with the TCM records.This method avoided man-made error to a certain degree in the process of recognizing and rebuilding of fascias.The study is significant to explore the morphologic comparability between the meridians and collaterals and interstitial connective tissues in human lower limb.
