摘要

The X-ray imaging of materials with low atomic number elements is difficult through a conventional photoabsorption contrast method whereas much higher contrast can be achieved by phase-contrast imaging. We have constructed a compact size imaging system using a microfocus X-ray generator with a few μm spot size. We present here the evaluation of basic characteristics and sample results, as well as future prospects.
