BACKGROUND
Although flexible endoscopy is only 25 years old, a new technology may soon be used to provide the same view of internal organs without inserting an instrument. This is virtual endoscopy.
METHODS
By acquiring patient specific high resolution digital images with a helical CT scan or MRI, individual organs can be graphically isolated or "segmented" into fully interactive 3-D reconstructions on a computer monitor. Applying sophisticated flight-tracking programs from military pilots, the organs can be "flown through", giving a view identical to endoscopy.
CONCLUSIONS
In the future we will fly through data instead of inserting endoscopic instruments for gastrointestinal endoscopic diagnosis.
背景
尽管柔性内窥镜技术仅有25年历史，但一项新技术可能很快会被用于在不插入器械的情况下提供相同的内脏视图。这就是虚拟内窥镜技术。
方法
通过螺旋CT扫描或MRI获取患者特定的高分辨率数字图像，各个器官能够在计算机显示器上以图形方式分离或“分割”成完全交互式的三维重建图像。应用来自军事飞行员的精密飞行跟踪程序，就可以“飞越”这些器官，从而获得与内窥镜检查相同的视图。
结论
未来，我们将通过数据“飞行”，而不是插入内窥镜器械进行胃肠内窥镜诊断。
