UNLABELLEDThis 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.

CONCLUSIONS1. 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.
