通过X射线光栅干涉测量法（一种X射线相位成像技术，即使是由轻元素组成的材料也能够进行高灵敏度X射线成像），以小于10 ms的曝光时间成功地获得了X射线相位断层照片。该高速X射线成像实验在BL 28 B2，SPring-8进行，其中白色X射线束可用，并且断层图像是从以100，000 fps的帧速率记录的投影图像重建的。该实验的建立将使人们有可能实现对不可重复的高速现象的三维观测，其时间分辨率小于10 ms。
An X-ray phase tomogram was successfully obtained with an exposure time of less than 10 ms by X-ray grating interferometry, an X-ray phase imaging technique that enables high-sensitivity X-ray imaging even of materials consisting of light elements. This high-speed X-ray imaging experiment was performed at BL28B2, SPring-8, where a white X-ray beam is available, and the tomogram was reconstructed from projection images recorded at a frame rate of 100,000 fps. The setup of the experiment will make it possible to realize three-dimensional observation of unrepeatable high-speed phenomena with a time resolution of less than 10 ms.
