The principle and progresses in X-ray 3D imaging using Synchrot ron Ra diation (SR) are introduced in this paper. Two types of X-ray 3D imaging techni ques, X-ray holograply and CT, and the theory and technology in high resolution 3D imaging with the combination of these two techniques-HCT, are described in detail. The digital methods for elimination the “twin image” noise from in-li ne holography are introduced, and the factors that limit the resolution are disc ussed. Some results of X-ray 3D HCT experiment with biological samples obtained in National Synchrotron Radiation Laboratory are shown.
