CT bulb tube with outer rotor structure

Abstract

The invention discloses a CT bulb tube with an outer rotor structure, which aims to provide the CT bulb tube with an outer rotor structure with good use effect, long service life and lower use cost. The CT bulb tube of the invention comprises a bulb tube shell (1), wherein a cathode (2) and an anode target (3) are respectively arranged at two ends in the bulb tube shell (1); the CT bulb tube of the invention also comprises a rotating device, wherein the rotating device comprises a stator (4), a rotor (5) and a fixed shaft (6); the rotor (5) is connected with the anode target (3); the stator (4) is arranged outside the bulb tube shell (1) and corresponds to the rotor (5) in position; the rotor (5) is sleeved outside the fixed shaft (6); a plurality of rolling balls (7) are arranged between the rotor (5) and the fixed shaft (6); and the rotor (5) is in rotatable fit with the fixed shaft (6) through the rolling balls (7). The invention can be widely applied in the technical field of CT bulb tubes.

Description

technical field [0001] The invention relates to a CT bulb, in particular to a CT bulb with an outer rotor structure. 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. When the CT bulb is used on a CT machine, because the heat capacity of the target plate is very large, generally 2M-6M, or even larger, it makes its own weight very large (the largest can reach more than 3kg), so the rotation system The bearing capacity of the bearing is very high. In theory, the bearing capacity is directly proportional to the size and volume of the bearing...

AI Technical Summary

Problems solved by technology

And it is a considerable expense (up to several hundred million U.S. dollars) to replace the CT tube every year.

Due to technology monopoly, this product is completely controlled by foreign countries, resulting in extremely high cost of using CT tubes, which many domestic hospitals cannot afford, which largely hinders the promotion and popularization of CT machines and related technologies in China

[0003] To sum up, due to the imperfect structure, the existing CT tubes have technical defects such as poor use effect, short service life and high use cost.
