Abstract
- To broaden the scope of phase-contrast X-ray imaging in biomedical applications, the energy of X-rays in a large-area imaging system using a two-crystal X-ray interferometer has been increased from 17.7 keV to 35 keV. The use of higher-energy X-rays makes it possible to observe larger samples having greater variation in density within shorter measurement periods, at higher spatial resolution, and at lower X-ray doses. After optimizing the imaging system for 35 keV X-rays, a 25 mm x 30 mm interference pattern with 50% visibility was generated at the Photon Factory. The system's capabilities are demonstrated by this pattern and a high-quality three-dimensional image of a rat heart.
