China University of Science and Technology has achieved "a major breakthrough in X-ray imaging in the past 20 years."

In the future, CT scans by patients will not only be more convenient and effective, but radiation may also be greatly reduced. The reporter recently learned from China University of Science and Technology that the National Synchrotron Radiation Laboratory has achieved "a major breakthrough in X-ray imaging in the past 20 years." It compensates for the insensitivity of traditional X-ray imaging technology to light-element materials, which is life science, Information science and medical diagnostics show promising applications.

It is understood that the current X-ray phase contrast imaging method is too cumbersome, the exposure time is too long, and the radiation dose is too high, which hinders the application of this new imaging technology. Recently, after several years of hard work, the imaging research team led by Prof. China University of Science and National Institute of Synchrotron Radiation Researcher Wu Ziyu has found that the absorption contrast is symmetrical in the two projection images with X-ray incidence and back incident. Degree is antisymmetric. Based on this principle, the research team proposed a new method of X-ray phase CT. The experimental results show that the new method overcomes the deficiencies of the conventional X-ray phase contrast imaging method and has the advantages of simple, rapid and low radiation dose. The existing medical X-ray CT technology is combined to form a new technique of X-ray phase CT that is easy to operate and has a low radiation dose.

After the relevant research papers were published, the reviewers were hailed as "a major breakthrough in X-ray imaging in the past two decades."
