ZEISS Xradia CrystalCT
The First Commercial MicroCT Crystallographic Imaging System
ZEISS Xradia CrystalCT uniquely augments the powerful technique of computed tomography with the ability to reveal crystallographic grain microstructures, transforming the way polycrystalline materials (such as metals, additive manufacturing, ceramics, pharmaceuticals and others) can be studied, leading to newer and deeper insights for your materials research.
Ground-Breaking Diffraction Contrast Tomography (DCT) On a MicroCT
Unlock the crystallographic secrets of your sample in your lab
An Expanded Range of Research Possibilities
DCT on a microCT brings the ability to image single-phase polycrystalline materials within reach of technical and industrial research labs, covering a wide range of metal, mineral, ceramic, semiconductor, and pharmaceutical samples in 3D. The purpose-built ZEISS Xradia CrystalCT incorporates precisely designed aperture and beam stop assemblies to harness divergent, polychromatic X-ray beams to illuminate a region of interest and increase sensitivity to weaker diffraction signals of polycrystalline samples.

Achieve Superior Contrast and Image Quality
ZEISS Xradia CrystalCT advances materials characterization, modeling, and discovery through ground-breaking diffraction scanning modes. Innovative DCT acquisition modes remove the limitations for larger sample sizes, providing you with the ability to research more sample types. Seamless large volume grain mapping enables scanning samples faster and with more accurate representation of data.

3D Grain Reconstruction
Fast, Precise, Automated Grain Data Indexing
After the first step in your workflow of initial acquisition you can then begin to reconstruct. Load your absorption tomography and your diffraction data into GrainMapper3D. Let it identify potential candidates for grain orientations of a given polycrystal by using back and forward projections.
An automated, iterative search for grains in the sample volume is your next step. Grain reconstruction results are stored as stacks of slices or volume datasets that contain the full description of the indexed grains. Eventually, share 3D CrystalCT results with your collaborators or customers using the standalone GrainMapper3D Viewer application.
3D Grain Mapping
All Your Information in One File
Your final step is to get out all the information you need in one single file. Shape, orientation and spatial locations of all grains in the sample volume are exported into an open data format.
Finish your experiment with subsequent analyses using customized software or simulation tools. The advanced indexing routines now support the more complex lower symmetry crystal systems.
