摘要

Coherence-contrast x-ray imaging--Which detects changes in the degree of coherence caused by the placement of a sample in an x-my interferometer-was developed for biomedical applications. Because the technique's sensitivity depends on the density gradient in the sample, it is particularly suitable for observing biomedical samples with large density differences, such as samples that include both biological soft tissue and bone. A measurement principle and method of this technique are described, and a fine coherence-contrast image of a mouse leg is given as an example result.
