X-ray tube assemblyX-ray is a kind of high-energy ray, its penetrability is very strong, but its absorption degree varies by substance. Relying on this characteristic, X-ray is widely used in cancer treatment, medical imaging, security inspection, industrial non-destructive testing and other fields. Nanotube X-ray source is an X-ray source based on carbon nanotubes. As a new type of X-ray source, carbon nanotube X-ray source has many advantages such as high photon efficiency, low power consumption, controllable emission, and easy integration. The development of nanotube X-ray sources will bring more technological breakthroughs to CT equipment.

Carbon nanotubes are one-dimensional quantum materials. Compared with traditional metals and polymer materials, carbon nanotubes have good electrical, thermal and mechanical properties. Relying on outstanding properties, carbon nanotubes have gradually become the most commonly used nanomaterials in field emission electron sources. Material.

Ray tubes are an important tool for making X-rays, depending on the type, carbon nanotubesX-ray tube assemblyIt can be divided into 2 categories: CNT digital X-ray tube and CNT ordinary X-ray tube. Among them, CNT digital X-ray tube is the mainstream product in the market, accounting for nearly 80%.

X-ray tube assemblyHot cathode technology is usually the main technology, but hot cathode X-ray sources have problems such as slow startup, high power consumption, and high ineffective radiation dose. The innovation of carbon nanotube X-ray sources is that carbon nanotube field emission cold cathodes replace hot cathodes. It endows the carbon nanotube X-ray source with many advantages such as low power consumption and controllable emission. Relying on its advantages, the carbon nanotube X-ray source is expected to bring structural breakthroughs to CT equipment, X imaging equipment, and medical DR equipment.
