The Key Components of CT Equipment - Development of New Technology of Spherical Tube

In this paper, the technical basis and latest progress of CT bulb are introduced, with emphasis on material innovation, superconducting technology, liquid metal bearing, low dose scanning and electron beam filtration. As the core component of CT equipment, the innovation of CT bulb technology significantly improves image quality, reduces radiation dose, improves efficiency, and extends the service life of the bulb. Domestic and foreign manufacturers have made remarkable progress in the field of CT bulbs, and domestic manufacturers, such as the 12th Institute of CLP, have made important progress in the development of CT bulbs, and successfully achieved independent research and development of high-end CT bulbs. Foreign manufacturers such as Siemens, GE, Philips and other manufacturers continue to innovate in liquid metal bearings, superconducting technology, new targets and other aspects to maintain technology leadership. In the future, CT bulbs will develop in the direction of personalization, intelligence, long life, miniaturization and portability, providing more accurate and low-risk technical support for medical image diagnosis.
