The foreign brand X-ray machine is about to end

In October of this year, Nanjing Kangzhong Photoelectric Technology Co., Ltd. will launch two world-first carbon nano cold cathode X-ray machines for security inspection and industrial inspection.

The X-ray machines widely used in the domestic market currently rely mainly on imports for core X-ray sources. Dr. Zhang Yan, Ph.D., Chairman of Cambridge University, UK, told reporters that the traditional X-ray source is to use heated metal wire inside a vacuum tube to heat up to thousands of degrees Celsius and use its high-energy electrons to bombard metal targets to generate X-rays. Photographs of packages, parcels, foods, industrial products, and buildings are not only harmful to radiation, but they are also very slow to take pictures and cannot take clear pictures of moving objects. In addition, traditional X-ray machines used in hospitals generally have more frequent replacement of X-ray sources, while imported X-ray sources are expensive, and high-end ones cost several hundred thousand yuan.

In 2008, Zhang Yan, who received a doctorate in electrical engineering from Cambridge University, served as deputy director of a large-scale electronic device research center. One of the projects he was responsible for was to manufacture ceramic tube X-ray sources. The ceramic tube X-ray source has a narrow application field. He thinks that if this technology is used in a glass tube X light source, the price can not only be greatly reduced, but also a broader application field can benefit more people. He decided to go back to business.

In October 2011, Zhang Yan established and established Nanjing Kangzhong Optoelectronics Technology Co., Ltd. in Nanjing to engage in the research and development of carbon nano cold cathode X-ray machines. Soon, the company obtained more than 10 patents and developed carbon nano cold cathode X-ray tubes and carbon nano cold cathode X-ray sources. The X-ray machine developed with this technology can take pictures in only a few milliseconds. It not only has low energy consumption and long life, but also has a 70% to 80% lower radiation hazard than conventional X-ray machines.

"After mass production, the price of our X-ray machines will be lower than that of traditional X-ray machines." Zhang Yan said that the "wrapped X-ray inspection machine" to be launched in October can be used in airport and subway security inspections; portable "carbon nano cold "Cathode X-ray machine" can be used for the detection of foods, drugs, and drugs, etc. Instantly find debris in packaged filling foods, foreign substances in Chinese herbal medicines, and drugs that are stored in various places. Now, the prototype has been tested at a domestic medical device company, a British safety inspection equipment company and several R&D institutions.

In the first quarter of next year, we will be able to establish our own production line and use 'carbon nano cold cathode X-ray machines' for medical, security, industrial inspection and other fields that use X-ray machines. "Zhang Yan is full of confidence.
