摘　　要：目的实现Ｉｎｔｅｒｎｅｔ上Ｗｅｂ模式的医学断层图像三维重建及高精度显示。方法用超高速ＣＴ扫描获得人体器官二维图像，基于ＪａｖａＡｐｐｌｅｔ编程，采用体绘制法完成二维图像的三维重建与显示。结果在重建的三维图像上清晰显示出了人体器官的解剖结构，尤其是心脏的整体形态及冠状动脉的走向；重建可在Ｉｎｔｅｒｎｅｔ上以Ｗｅｂ模式跨平台运行，并且在三维图像上可进行手术模拟操作。结论①用ＪａｖａＡｐｐｌｅｔ实现基于Ｗｅｂ的医学断层图像三维重建是可行的，并对三维图像的临床应用起推动作用；②通过三维重建显示人体器官的立体形态，尤其是冠状动脉的解剖结构在临床上有很大参考价值。Purpose To reconstruct three dimensional medical images in Internet based on Web and to achieve highly realistic display. Methods Getting two dimensional images of human organs from ultrafast CT as sources,applying the volume rendering techniques to rebuild and display three dimensional images based on Java Applet program. Results The anatomic structure of human organs can be displayed clearly in reconstructed three dimensional images,especially the gross morphology of the heart and the trail of the coronary artery.This program can be run in Web browser on many different kinds of computers.Surgical operation can be simulated on the three dimensional images. 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 great references to clinic.
