Which is better for industrial CT detection?

At present, there are quite a few industrial CT brands in China, including Zeiss, GE, yxlon and Nikon, all of which are well-known in the industry. We can't tell which is the best, because each has its own characteristics. For example, Zeiss's products pursue high resolution, mainly scanning small samples, which are generally difficult to scan when the diameter exceeds 5 mm, and the maximum voltage is only 160Kv, and the longest scanning time is five hours, which is suitable for university research institutes. Ge's products belong to the American General Electric Company, which is a leading company in China, because his family can be equipped with two tubes, which can not only scan small samples with high resolution, but also cut into micron tubes to scan large and medium-sized samples with high penetration. The practical application is relatively high. If you want to know about the products, you can search the official website of General Electric or Shanghai Huaying Testing. I attended a soil conference held by Huaying Testing in 19 and visited their laboratory, which was very professional and strong. Yxlon's two-position X-ray inspection equipment is relatively complete, and their family seems to be more inclined to sell two-dimensional ones in the market, and I have heard less about other contents; Nikon's is also good, but the core components are outsourced and cannot be made by themselves;
