ABSTRACT
We present a method for tomographic reconstruction of objects containing several distinct materials, which is capable of accurately reconstructing a sample from vastly fewer angular projections than required by conventional algorithms. The algorithm is more general than many previous discrete tomography methods, as: (i) a priori knowledge of the exact number of materials is not required; (ii) the linear attenuation coefficient of each constituent material may assume a small range of a priori unknown values. We present reconstructions from an experimental x-ray computed tomography scan of cortical bone acquired at the SPring-8 synchrotron.

    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...
