摘要
目的探讨一种基于中国数字化人体(CVH)的冠状动脉CT血管造影(CTA)多维可视化方法在于CTA中观察冠状动脉结构和辅助诊断的可行性。方法获取CVH断层数据集和临床冠状动脉CTA影像,分别对冠状动脉进行分割、提取中心线和标定,获得右冠状动脉(RCA)、左主干(LM)、前降支(LAD)和回旋支(LCx)等节段,然后使用曲平面重建技术对冠状动脉横断面、冠状面、矢状面、拉伸曲平面和拉直曲平面等多平面进行重建,并在此基础上使用形态学方法计算两者的冠状动脉直径、长度、面积和曲率等影像特征进行比较。结果该方法实现了CVH和CTA在二维和三维层面的对照显示。结论CVH与CTA的冠状动脉多维可视化重建对于临床辅助诊断和影像学教学都具有重要意义。
Objective To explore the feasibility of a multi-dimensional visualization method of coronary arterial CT angiography(CTA)based on Chinese visible human(CVH)for observing coronary artery structure and assisted diagnosis in CTA.Methods The CVH dataset and clinical coronary arterial CTA imaging were obtained respectively,then the coronary artery were segmented,the centerline was extracted and the main branch including the right coronary artery(RCA),left main(LM),left anterior descending(LAD),left circumflex artery(LCx)and so on,,etc.were labeled.Next,the curved planar reconstruction techniques were used to reconstruct the coronary cross-section,coronal,sagittal,stretched planar reformation and straightened planar.On this basis,the morphologic method was used to calculate the image features such as the coronary diameter,length,area and curvature were calculated for conducting the comparison.Results This method realized the contrast display of CVH and CTA at the 2D and 3D levels.Conclusion The coronary multi-dimensional visualization reconstruction of CVH and CTA is of great significance for clinical assistant diagnosis and imaging teaching.
