Reveal contrast that has never been seen before ZEISS PhaseEvolve Process your high resolution 3D phase contrast datasets to further enhance contrast. Clearly distinguish different parts of your low contrast samples. PhaseEvolve, one module of ZEISS Advanced Reconstruction Toolbox (ART), enables easier and faster 3D segmentation of phase contrast data acquired on ZEISS X-ray microscopes. Propagation-based phase contrast tomography is a powerful and highly effective X-ray microscopy technique that reveals fine features such as cracks, voids and other micrometer-scaled structures in low absorbing materials. However, the distinct phase fringes that decorate these small features often make it hard to distinguish material phases, further challenging the process of image segmentation required for quantitative 3D analysis. PhaseEvolve is your software solution to remove the phase fringes from phase contrast tomography data and produce artifact free, superior quality data that is easily segmented and quantified. Use the easy-to-use guided user interface to post-process your reconstructed 3D tomograms and get cleaner, phase-free data allowing you to focus on the smallest microstructural features that are critical to your needs. Reconstructed 2D slice from the scan volume along with corresponding histograms are shown for raw (left) and PhaseEvolve processed (right) tomography data. Processed data provides artifact free high contrast data with a histogram that is enables easy segmentation. Seeing beyond apeutic use, treatment or medical diagnostic eridence.
