Large-area (25 x 20 mm) phase-contrast X-ray imaging was attained by using a skew-symmetric two-crystal X-ray interferometer. The sub-nrad angular control required to operate the X-ray interferometer was achieved with a sleeve bearing and a feedback-positioning system. As a demonstration, measurements of a phase map of a rat's liver and a phase-contrast tomographic three-dimensional image of a piece of a rabbit's liver were performed at the Photon Factory using 0.07 nm synchrotron radiation X-rays.
通过使用斜对称双晶X射线干涉仪实现了大面积（25×20毫米）的相衬X射线成像。利用套筒轴承和反馈定位系统实现了操作X射线干涉仪所需的亚纳弧度角控制。作为演示，在光子工厂使用0.07纳米的同步辐射X射线对大鼠肝脏的相图和一块兔肝脏的相衬断层三维图像进行了测量。
