carbonado_a_view0.jpg2 carbonado diamond chips were imaged using microtomography. The first was a small chip, about 4 mm in diameter. This was imaged with 6.8 micron pixel resolution. Two data sets were collected. carbonado_a contains the top half of the diamond, while carbonado_b contains the bottom half. The following are projection radiographs (0 degrees and 90 degrees) and tomographic reconstructions of selected slices from the carbonado_a and carbonado_b data sets. In these images low X-ray absorption is white and high absorption is dark. In each reconstructed cross section air-filled pores, and high-Z inclusions can be seen.
The carbonado_a data can also be viewed as an MPEG movie. This movie consists of about 500 frames, each frame being one reconstructed slice in the sample. For best results when using Microsofts Active Movie player, right click and enable Frames, so that the left and right arrow keys can be used to step through the movie one frame at a time.

A second, larger chip was also imaged. This was done at slightly lower magnification, 10 micron pixels. Only the top 70% of this chip was imaged, data set carbonado_c.
