- Abstract
- We obtain an enhanced phase-contrast image of biological samples from the single-shot X-ray phase-contrast imaging technique by using weighted mean filter imaging processing. The center-weighted mean filter is applied to Moiré-less 1st-harmonic image restored by Fourier-transform phase-retrieval method. Consequently, the quality of X-ray differential phase-contrast image is drastically improved. The signal-to-noise ratio has been enhanced at least 25.9 % by the enhancement process with the weight value of 1.3. The enhancement of phase information can be explained by the behavior of weight filter in the complex domain.
