采用活体器官的CTA头部断层扫描图像为原始数据,实现了颈动脉的三维重建及相关空间参量的测量。这种成像方法可以无创、活体对血管内壁进行准确拓扑学建模,清晰观察颈动脉管壁及外周结构,呈现颈动脉与周围组织的解剖学结构关系,评价颈动脉狭窄及空间位置、管壁斑块、血栓或肿瘤的结构特征。该研究成果弥补了目前影像诊断的不足,在模拟仿真手术及医学影像教学研究等方面有一定的应用价值。
Using CTA head CT images of living organism as raw data, 3D reconstruction of carotid artery and measurement of related spatial parameters were realized. This imaging method can be non-invasive, in vivo accurate modeling of the inner wall of the blood vessel, clear observation of the carotid artery wall and peripheral structure, showing the anatomy of the carotid artery and surrounding tissue structure, evaluation of carotid artery stenosis and spatial location, wall Structural features of plaque, thrombus or tumor. The research results make up for the current lack of image diagnosis, in simulation and surgery and medical image teaching research has some application value.
