摘要
实现 Internet上 Web模式的医学图像三维重建及显示。基于 Java Applet编程 ,利用数字签名解决 Ja-va安全限制 ,读取本地图像。采用体绘制法完成二维图像的三维重建与显示。由超高速 CT获得人体器官的断层图像 ,在 Web上重建出了心脏、冠状动脉、头颅、颈椎、骨盆的三维解剖结构。重建可在 Internet上以 Web模式跨平台运行 ,且在三维图像上可进行切割模拟操作。结论 1用 Java Applet实现基于 Web的医学图像三维重建是可行的 ,并对三维图像的临床应用起重要推动作用 ;2基于 Web重建的三维医学图像 ,其精度能够满足临床要求 。
This study was conducted to reconstruct three dimensional medical images based on web and to achieve highly realistic display.Using the volume rendering techniques to reconstruct and display three dimensional images in Java Applet program and utilizing signed Applets for solving security problem,We got two dimensional images of human organs from ultrafast CT as sources and reconstructed the organs configuration of heart ,coronary artery, head, cervical vertebrae, and pelvis. This reconstruction can be run in Web browser on different kinds of computers and for virtual surgical planning. Conclusions: 1.Three dimensional medical image reconstruction in Web browser implemented by Java Applet is feasible, which will prompt clinical use of three dimensional images. 2. The solid conformation of human organs, especially the anatomic structure of the coronary artery, can be displayed by using three dimensional reconstruction techniques, which may offer more information to clinics.
