摘要：

背景：三维图像重建是开展膝关节虚拟研究的基础。关节周围韧带、软骨、半月板等结构分割重建报道较少。
目的：在前期大量膝关节标本解剖研究的基础上，利用CT及MRI数据，三维重建包括关节周围韧带、软骨、半月板等结构在内的膝关节模型。
方法：采用1例人体成年膝关节标本CT、MRI薄层扫描数据，导入Mimics 10.01分别三维重建膝关节骨、软骨、韧带及半月板等结构，利用逆向工程软件Geomagic 8进行及图像配准处理。
结果与结论：三维重建了包括关节周围韧带、软骨、半月板等结构在内的膝关节模型，为建立相应膝关节有限元模型奠定了基础。

Abstract:

BACKGROUND: Three-dimensional reconstruction is a foundation of knee joint stimulation. There are few reports regarding structural subdivision and reconstruction of ligament surrounding joint, cartilage, and meniscus.
OBJECTIVE: To reconstruct a 3D knee model with ligments, cartilage and meniscus based on previous knee joint anatomy using CT and MRI data.
METHODS: CT and MRI data of 1 adult knee joint were harvested and import in Mimics10.1 to reconstruct the structures such as bone, atricular cartilage, meniscus and ligaments of knee joint. The registration was performed with reverse-engineering software Geomagic 8.
RESULTS AND COCNLUSION: 3D knee joint model with bone, meniscus, ligaments and articular cartilage was reconstructed, which lays a foundation for finite element analysis of corresponding knee joint.
