We report on millisecond-order X-ray tomography with grating-based X-ray imaging using a white synchrotron X-ray beam. We performed a compressed sensing technique for tomographic reconstruction and successfully obtained a phase tomogram for a polypropylene sphere with a temporal resolution of 2.0 ms. Our approach will make it possible to realize millisecond-order four-dimensional X-ray tomography but also to markedly reduce the radiation damage of samples including polymer and biological materials, and will be widely used in various fields of material and life sciences in the near future.
