Rotating around you, the x-raytube and electronic x-ray detectors are located opposite each other in a ring, called a gantry.
有个称为龙门的环状物在你周围旋转，环上有若干对X射线管和电子X射线探测器在两侧。

The phases of corrosion products on underground steel tube and their changes with depth of rust layer were analysed using Mossbauer effect, X - ray diffraction and proton X -ray fluorescence analysis.
The X-ray backscattering from the inner electrodes and the tube wall of an X-ray image intensifier (XRII) will degrade the spatial resolution and the contrast of an output image.
