computerized tomography(CT)
计算机X射线断层术
The process of producing a picture showing human body organs in cross section by first electronically detecting the variation in X-ray transmission through the body section at different angles, and then using this information in a digital computer to reconstruct the X-ray absorption of the tissues at an array of points representing the cross section.
用计算机产生一幅表示人体器官断层图的处理方法,首先用电子技术测试X射线在某一断面上从不同角度穿过人体时 所产生的变化;然后将此信息送入计算机以重构X射线穿过该断面薄层任一点时的吸收情况, 以表示该断面。 |
