Imaging by using wave nature of quantum beam

Quantum beams, such as X-rays, are used to visualize internal structures of various materials having the scales ranging from atoms to human. However, there is a problem that sufficient contrast is not obtained for materials consisting of light elements, such as polymers, light metals, and biological soft tissues. The use of phase contrast based on the wave nature of X-rays is significant for overcoming this problem and enhances the usefulness of quantum beams tremendously. We have innovated in X-ray imaging technology by developing X-ray phase measurement, releasing groundbreaking results beyond conventional expectation. Based on quantum beam physics, we are developing unique experimental environment and pioneering advanced imaging research. This technology is attractive for practical applications, and we are also conducting various collaborations with industry.
