摘要

目的:探索膝关节三维数字化模型的重建及可视化方法。方法:利用1例志愿者的右侧膝关节核磁共振成像（Magnetic resonance imaging

MRI）薄层扫描数据

采集二维图像数据

应用Materialise公司的交互式医学图像控制系统（Materialises interactive medical image control system

Mimics）软件重建膝关节骨性结构及半月板、交叉韧带、侧副韧带等软组织的三维数字化模型

并对半月板和韧带进行断面测量和模型立体测量。结果:利用MRI数据

应用Mimics软件成功建立膝关节三维可视化模型

重建的膝关节骨性结构及相关软组织形态逼真

解剖学标志清晰

可以不同颜色、任意组合显示

并可对模型放大、缩小、旋转等全方位观察。对膝关节测量结果数据显示

膝关节相关结构断面测值与重建模型立体测值基本一致。结论:基于MRI薄层扫描数据重建活体膝关节三维可视化模型

具有较高的真实性和准确性

并可对其形态结构进行定量观测。重建的膝关节三维模型有助于教学和形态功能研究

并为进一步开展膝关节有限元分析和虚拟仿真手术奠定基础。

Abstract

Objective:To explore the methods for reconstruction and visualization of three-dimensional(3D) models of knee joint.Methods:The MRI thin layer scanning data set of a donor’s right knee joint were used;two-dimensional image data were collected.The 3D models of knee joint including the bones

meniscus

cruciate ligaments and collateral ligaments were reconstructed by using Mimics software.The meniscus and ligaments were measured cross-sectionally and tridimensionally.Results:The 3D models of knee joint were reconstructed successfully based on the MRI images by using Mimics.The model’s morph of the bones and soft tissues were vivid and the anatomy signal was limpid.The models reconstructed could be displayed by different colors and combined randomly.The models could also be viewed in any direction by zooming in

zooming out

rotating and so on.The measured data of knee joint revealed that the sectioned information was the same as the spatial ones.Conclusion:The 3D models of knee joint which look veridical and accurate can not only be reconstructed explicitly by using MRI lamellate images

but also be measured.The reconstructed 3D models of the knee joint are helpful for anatomy teaching and study

and it can also establish the basis for the finite element analysis and virtual reality surgery.
