Avizo for PCX

VSG - Visualisation Sciences Group

Avizo software, from VSG - Visualisation Sciences Group, can now be combined with PCX micro-CT systems to offer 3D imaging for low density materials.

Traditional x-ray techniques seriously limit imaging of very small or weakly absorbing features and make extraction of subtle textural information from the image extremely difficult. PCX systems, developed and manufactured by XRT, are specifically designed to capture and retrieve both phase and absorption contrast enabling high contrast imaging of low density materials in a broad range of applications, from materials science to micro-electronics, food technology, earth sciences, and more.

PCX series is now combined with Avizo software for high-end 3D visualisation and quantitative analysis of micro-CT data, delivering a superior 3D imaging solution for challenging materials structure analysis.

High-resolution phase and absorption contrast phenomena play important functions in improving contrast for x-ray images with many types of weakly absorbing materials (that can either stand alone or be in the company of more dense structures), even with the most difficult low contrast samples such as paper, plastics, composites, geo-polymers, metal foams, ceramics, food texture, and more.

The imaging geometry used in XRT’s PCX produces images containing both absorption and phase contrast components which, when combined, allow faint objects of similar atomic number, and small features, not otherwise visible to be imaged in superb detail.

XRT now offers Avizo software as an additional tool for advanced 3D visualization and analysis of microtomography data generated using PCX products. This allows users to obtain realistic 3D models, to take virtual sections through the sample, and to provide enhanced and highly concise insight into the internal arrangement of components; the thickness, integrity and registration of layered structures can reveal images of internal cracks, voids and delaminations without destroying the sample.
