摘　　要：目的　研究基于网络重建心脏和冠状动脉的三维图像 ,并探讨其准确性。　方法　 2例新鲜心脏标本冠状动脉注入造影剂后 ,超高速 CT(U FCT)增强容积扫描 ;另取 1例冠状动脉造影病人的 UFCT增强容积扫描的图像。分别对原始图像格式转换 ,噪声消除 ,兴趣区选择。利用 Java编制基于网络运行的三维重建软件 ,并对心脏和冠状动脉进行重建。　结果　重建出的心脏和冠状动脉图像逼真 ,动脉主干和分支与相应的 UFCT平片显示的结构相近 ,心脏可任意角度旋转与切割。　结论　基本实现心脏和冠状动脉在 Internet网上的重建 ,为人体器官和组织的三维重建提供一条新的途径。Objective To reconstruct three-dimensional (3D) image of heart and coronary artery on internet and explore the reliability. Methods After the contrast medium was injected into coronary artery of 2 heart specimens, hearts were scanned by UFCT with enhancement volume. One patient's UFCT images of coronary artery angiography were also chosen.Then the primitive images were transposed format, removed noise, specified interesting areas. 3D software on server was applied to reconstruct heart and coronary artery. Results The reconstructed 3D images of the heart and coronary artery were realistically displayed, freely rotated and transected.Main parts and branches of coronary artery were similar to those in the images of the UFCT. Conclusion Heart and coronary artery can be reconstructed on internet,which offers a new approach for reconstructing organs and tissues of human being.;
