Description
X-ray CT scans of phantom with 208 19-mm (3/4") diameter glass spheres in hexagonal pattern, used for evaluating 3D data processing. Voxel Size is variable; data provided with varying degrees of down-sampling. Data reduced to 8-bit TIFF from 16-bit original. Please acknowledge The University of Texas High-Resolution X-ray CT Facility (UTCT) when using this data.
