X-ray technology breakthrough is expected to make a simple CT safer

Reporter recently learned from University, the school Wu since Beijing Jade researcher-led synchrotron radiation facility and Hefei national synchrotron radiation laboratory, joint research group in the imaging x-ray phase-contrast imaging of major breakthroughs in the field, its research results to overcome medical x-ray CT technology x-ray phase-contrast imaging methods, to form a more rapid, sensitivity higher, more security x-ray phase CT technology laid the Foundation.

The study results published in the recently published international authoritative journals of the United States Academy of law, be reviewers praised as "the last 20 years x-ray imaging research breakthroughs."

From x-ray discovered so far in 100 years, traditional absorption of x-ray imaging techniques in medicine and biology, clinical diagnosis, safety inspections, and many other fields have been widely used.

However, its Imaging heavy element-based objects (such as bones, metal, etc.) are more sensitive to get a clear image, and the light elements primarily biological soft tissues (such as early-stage cancer, blood vessel), polymer material (such as cellular plastics, carbon fiber, high polymer) can only be blurred images. By contrast, in the last decade of the new developed x-ray phase-contrast imaging provides significant advantages to light elements of biological soft tissues for high-definition (contrast) image. But because the imaging method cumbersome, imaging long, radiation dose is too high, not suitable for Biomedical Imaging requirements of samples, difficult and medical x-ray CT technology.

Wu since jade leadership research group, utilizing x-ray positive incident and negative incidence absorption same, refraction angle opposite principles, to overcome the challenges of research programmes.

They have and the University of Tokyo, Japan and Switzerland synchrotron x-ray imaging expert cooperation, on the mouse brain tissue, joints, launched a series of experiments, was entirely sure of the results of the experiment. The new method has a simple, fast, low doses of radiation (radiation dose to reduce at least 50%), and existing medical x-ray CT technology, easy operation, radiation dose low x-ray phase CT new technology.
