CT增强扫描图像椎动脉和颈内动脉的三维重建研究

Study on 3D-reconstruction of vertebral artery and internal carotid artery based on CT strengthening scanning images

目的:探讨CT增强扫描图像在椎动脉、颈内动脉3D可视化技术中的应用。方法:1例经CT增强连续扫描检查的成人患者数据集,应用Mimics8.11对图像血管进行分割,三维重建椎动脉、颈内动脉颅内段数字图像。结果:椎动脉、颈内动脉颅内段三维重建数字图像清晰,能够准确的3D显示该血管解剖形态结构及其在颈椎、颅骨内的位置和毗邻关系。结论:三维重建图像可以提供复杂血管动态解剖,为临床诊断提供了直观的、数字化解剖参考。

Objectives： To discuss the application of CT strengthening scanning images on 3D-reconslruction of vertebral artery and internal carotid artery. Methods： CT strengthening scan images from one adult patient were conducted in Mimics 8.11, and blood vessels of image segments were carries out for reconstructing 3D-model of vertebral artery and internal carotid artery. Results： By this way, the digital model of vertebral artery and internal carotid artery can be performed, with precisely displaying of blood vessels and their location and adjacent relationship. Conclusions： The 3D-reconstruction images can provide anatomic references of vessels, which is valuable for clinic diagnose.
