CTDI was reduced and X-ray tube efficiency is improved.

它降低了X线剂量指数，提高了球管效率。

This avoids ion bombardment on an electron emitter (111) of the X-ray tube (100).

这避免了对X射线管(100)的电子发射器(111)的离子轰击。

The purpose is to improve the performance of flash X-ray tube produced at present time.

使目前生产的闪光X射线管性能得到进一步改进。

Existing scanners usually have but a single X-ray tube. This is rotated around the patient, taking pictures as it goes.

现存的放射机通常只有一个X射线管，围绕一周患者进行拍摄。

Rotating around you, the x-ray tube 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。
