摘要:

为充分挖掘CT图像中的医学诊断信息, 提高CT图像的三维重建效果与可视化程度, 研究了基于Mimics平台的CT图像三维重建算法。将腹部16排螺旋CT图像导入Mimics系统, 利用系统图像分割、 蒙版编辑和区域增长等功能模块, 将脾脏器官由腹部CT切片图像中完整分离出来, 并可进行任意角度的放大, 缩小等操作。与传统方法相比, 其实现的对人体器官、 骨骼和组织的CT图像的三维重建与可视化处理结果, 更加接近于真实器官的生理解剖结构。

Abstract:

To understand and dig clinical information of CT images, and to study the method of 3D reconstructionand visualization of CT image, we present an algorithm of 3D reconstruction. A group of 16 row spiral CT images of the abdomen of the human body was imported into Mimics 10.01 using the tools thresholding, mask editing, region growing and reconstruction. Spleen was separated from the whole abdomen CT images and reconstructed. It can be o
bserved from any perspective, zoomed in and out. The experiment results show that by using proposed 3D reconstruction algorithm, the spleen reconstructed is closer to its real 3D structure. It can provide further data in detail for medical research.

Key words: algorithm, Mimics software, 3D reconstruction
