日前,香港大学医学院新引进一种虚拟大肠镜技术,利用电脑可准确扫描检查出肠癌及息肉等疾病,比之传统的内窥镜既安全又便宜。 虚拟大肠镜技术或大肠电脑扫描是运用螺旋电脑扫描产生大肠的X光影像,结合电脑仿真技术,使平面电脑扫描影像变作立体动画影像。 据香港大学医学院消化肝脏副教授王振宇解释,虚拟大肠镜技术是将一条小管放在肛门口或直肠然后充气操作,显示出腹部及盆腔器官,通过电脑扫描形成立体影像,检查大
A few days ago, the Hong Kong University School of Medicine introduced a virtual colonoscopy technology. Using a computer to accurately scan for diseases such as bowel cancer and polyps, it is safer and cheaper than traditional endoscopes. Virtual colonoscopy or large intestine computer scanning is the use of spiral computer scanning to produce large intestine X-ray images, combined with computer simulation technology, so that the flat computer scan images into three-dimensional animation images. According to Wang Zhenyu, Associate Professor of Digestive Liver Medicine at the Hong Kong University School of Medicine, virtual colonoscopy is a small tube placed on the anus or rectum and inflated. It shows abdomen and pelvic organs. It is scanned by computer to form a three-dimensional image.
