CT球管主要由灯丝、靶、靶轴、管套、高压系统这样几部分组成。球管工作时,灯丝上通有电流。灯丝电流电子在外加高压系统产生的强大电场作用力的驱动下,高速溢出,轰击到球管靶面上,产生X射线。CT球管是CT设备的中心部件之一,只有当CT球管提供稳定、高质量的X射线,CT的一切功能 CT tube mainly by the filament, target, target shaft, casing, high-pressure system is composed of several parts. Tube work, through the filament current. Filament current electrons in the high-voltage system coupled with the strong electric field generated by the drive, high-speed overflow, bombardment to the target tube surface, resulting in X-ray. CT tube is one of the central components of CT equipment, and only when the CT tube provides stable, high-quality X-rays, all the CT functions
