In order to promote the development of China's radiological nondestructive testing technology and equipment, education and scientific research, the "2023 Radiological Nondestructive Testing Technology Exchange Conference" sponsored by the Nondestructive Testing Branch of the Chinese Mechanical Engineering Society, co-organized by the Key Laboratory of Materials Testing and Evaluation of China National Nuclear Corporation, and undertaken by the Key Laboratory of Nondestructive Testing Technology of the Ministry of Education of Nanchang Hangkong University was held in Haiyan, Jiaxing, Zhejiang Province from July 16 to 19, 2023. With the theme of "Green High Sensitivity Intelligent Radiographic Detection Technology", the conference attracted experts, scholars and practitioners from major universities, scientific research institutes, enterprises and testing institutions across the country.

Some members of our laboratory participated in this event and conducted in-depth exchanges with industry peers on cutting-edge technology, system integration, and industrialization direction in the field of radiographic detection. During the meeting, the members of the laboratory visited the exhibition of various types of radiographic detection instruments and equipment, and conducted technical docking and discussion with a number of units on the independent research and development achievements of the laboratory in recent years in multi-spectrum X-ray detection, spectral imaging CT, non-scan DR system, etc., so as to promote the deep integration of industry, university and research.

In the paper exchange session of the conference, the relevant papers submitted by the laboratory team covered the design of high-resolution flat panel detector system, the substance identification algorithm based on spectral data, and the new scheme of online detection of composite materials, which were positively evaluated by the participating experts. The related research shows the technical reserves and engineering application prospects of the laboratory in high-performance X-ray nondestructive testing equipment and intelligent image processing.

Through this meeting, the laboratory not only kept abreast of the latest technical trends and development trends in the radiological nondestructive testing industry, but also further expanded the cooperation opportunities with domestic industry experts and enterprises. In the future, the laboratory will continue to focus on the quality assurance needs of major national equipment and key materials, deepen scientific research and engineering transformation in the direction of high-end nondestructive testing technology, and contribute to the development of intelligent testing technology in China.
