目的构建3D真人侧脑室解剖模型,用于显微神经解剖教学和临床手术计划。方法以1例36岁健康成年志愿者176张头颅MRI T2加权二维断层图像图片为原始数据,联合应用Matlab、Geomagic和Maya等软件对原始图像进行预处理,轮廓线提取,三维重建形成3D模型,然后对模型和影像进行关联。结果根据176张原始图像数据成功完成了人侧脑室三维模型的重建,计算证实模型轮廓线与原始图像边缘吻合较好,经过3D模型与MRI数据场关联后所得模型具有更好的视觉效果。所建模型可任意旋转、放缩,从各个角度观察。结论成功构建的模型能够重复观察和研究且不受时间限制,也没有手术的压力。该模型也可为进入侧脑室目标部位提供潜在的外科练习,为后续指导临床实践奠定了基础。
Objective To construct a 3D human ventricle anatomy model for the anatomic teaching of micro-nerves and clinical surgical planning. Methods One hundred and sixteen healthy 36-year-old healthy volunteers were taken as the raw data, and the images were preprocessed by using Matlab, Geomagic and Maya software, contour extraction and 3D reconstruction to generate 3D models , Then associate the model with the image. Results The reconstructed 3D model of the human lateral ventricle was successfully completed based on the original data of 176 images. The calculated contour of the model agrees well with the edge of the original image, and the obtained model has a better visual effect after the correlation between the 3D model and the MRI data field. The model can be arbitrarily rotated, zoom, from all angles. Conclusions Successful models can be observed and studied repeatedly without time constraints and without surgical pressure. The model can also provide potential surgical practice for entering the target area of the lateral ventricle and lay the foundation for further clinical practice.
