Quantitative Mass Density Image Reconstructed from the Complex X-Ray Refractive Index.

Quantitative Mass Density Image Reconstructed from the Complex X-Ray Refractive Index.

We demonstrate a new analytical X-ray computed tomography technique for visualizing and quantifying the mass density of materials comprised of low atomic number elements with unknown atomic ratios. The mass density was obtained from the experimentally observed ratio of the imaginary and real parts o...
