An X-ray stereo imaging system with synchrotron radiation was developed at BL20B2, SPring-8. A portion of a wide X-ray beam was Bragg-reflected by a silicon crystal to produce an X-ray beam which intersects with the direct X-ray beam. Samples were placed at the intersection point of the two beam paths. X-ray stereo images were recorded simultaneously by a detector with a large field of view placed close to the sample. A three-dimensional wire-frame model of a sample was created from the depth information that was obtained from the lateral positions in the stereo image. X-ray stereo angiography of a mouse femoral region was performed as a demonstration of real-time stereo imaging. Three-dimensional arrangements of the femur and blood vessels were obtained.
利用同步辐射开发了一种 X 射线立体成像系统，该系统位于 SPring-8 的 BL20B2 上。宽 X 射线束的一部分被硅晶体布拉格反射，产生与直接 X 射线束相交的 X 射线束。样品放置在两条光束路径的交点处。通过放置在靠近样品的大视场探测器同时记录 X 射线立体图像。从立体图像中的横向位置获得的深度信息创建了样品的三维线框模型。作为实时立体成像的演示，对小鼠股骨区域进行了 X 射线立体血管造影。获得了股骨和血管的三维排列。
