Problems solved by technology

However, the anode target of the traditional rotating anode CT tube is not in contact with the shell of the CT tube, so that the heat dissipation of the anode target can only be through thermal radiation and heat convection, and the heat dissipation speed is slow and the heat dissipation effect is poor.

Abstract

The invention discloses a rotating anode CT (computed tomography) bulb tube which comprises a bulb tube core, a bulb tube support (12), a driving device and a cathode static device. The bulb tube core is a vacuum sealing device and comprises a metal bulb tube shell, an anode target (3) and a cathode (4), the anode target (3) is connected into the bulb tube shell, the cathode (4) is positioned in the bulb tube shell and corresponds to the anode target (3), a cooling oil inlet and a cooling oil outlet are arranged on the bulb tube support (12), the bulb tube core is placed in an internal cavity of the bulb tube support (12), the driving device drives the bulb tube shell and the anode target (3) connected on the bulb tube shell to rotate, the cathode static device comprises a first magnet (5) and a second magnet (6), the first magnet (5) is connected on the cathode (4), and the second magnet (6) corresponds to the first magnet (5) and is connected on the bulb tube support (12). The CT bulb tube is fine in anode cooling effect, long in service life and high in rotating speed.

Description

technical field [0001] The invention relates to a CT bulb, in particular to a rotating anode CT bulb. Background technique [0002] CT machine is a full-featured disease detection instrument. With the development of technology, CT machine has been popularized due to its high resolution capability and intuitive and accurate diagnosis effect, and has been widely used in the medical field. CT tube, also known as X-ray tube, is the core component of CT machine and is used to generate X-rays. Whether the technology of CT tube is perfect or not directly affects the working effect of CT machine. [0003] A CT tube usually includes the following parts: shell, cathode, anode and so on. By pressurizing the cathode, the cathode emits electrons, which are focused to bombard the anode target. The anode target is bombarded by electrons to generate X-rays, and heat is generated and emitted. The power of traditional fixed anode CT bulbs is limited due to the high temperature of the anode...
