ZEISS PhaseEvolve for Contrast Enhancement

If a user's typicalimage contrastis specific to X-Ray microscopy and is overprinted by phase effects in low-medium density samples or high-resolution datasets, they can use PhaseEvolve, a reconstruction technique for post-processing thatallows users to improve the contrast of the image. They can also perform more precise quantitative analysis with enhanced contrast and segmentation of results.

The image on the right shows an application of PhaseEvolve to a pharmaceutical powder sample. High resolution or low kV imaging can result in inherent material contrast being obscured by phase contrast artifacts. PhaseEvolve effectively removes phase fringes to enhance image contrast and improve segmentation results. Image Credit: Carl Zeiss Raw Materials
