| 摘 要： | 目的应用虚拟现实(VR)技术,实现室间隔缺损(VSD)的心内三维超声虚拟现实诊断.方法建立10个新鲜离体猪心VSD模型,采集三维超声图像进行三维重建和可视化,建立心内三维超声VR系统.结果应用VR技术后,显示缺损的形态、部位、数目和邻近解剖结构间的关系,均与与解剖后观察结果一致.测量三维重建并虚拟显示后的VSD面积、最大径和最小径,结果测得数据与实测值高度相关(r＞0.95,P＜0.01).结论 VR为小儿先天性心脏病三维超声诊断提供了一种新方法.

| Abstract: | Objective To investigate the diagnostic value of three dimensional echocardiography (3 DE) with virtual reality (VR) in detecting ventricular septal defect (VSD). Methods In this study, there were 10 VSDs with different size and shape modeled in ten fresh explained porcine hearts. HP SONOS 5500 imaging system was employed for 3 DE reconstruction and virtual reality computing techniques was used for visualization. Results The results showed that all VSDs were successfully reconstructed. The site and geometry were well appraised in its true form. The area, maximum and minimum diameter of VSD were measured on 3D reconstruction and compared with independent measurements on anatomy. Good correlation was obtained ( r >0.95, P <0.01). Conclusion VR provides a new method for 3 DE in diagnosing congenital heart disease. |
