Taking advantage of the fact that an X-ray Talbot interferometer functions with X-rays of a broad energy band width, high-speed X-ray phase imaging and tomography have been achieved by using white synchrotron light. An X-ray phase tomogram could be measured with a 0.25 s exposure. Furthermore, a series of X-ray phase tomograms, in other words, a four-dimensional X-ray phase tomogram, could be reconstructed with a tomogram frame rate of 25.5 fps. This achievement advances X-ray phase imaging/tomography from a technique for static imaging to one for dynamic imaging of weakly absorbing objects.
