SOURCE GRATING FOR X-RAYS, IMAGING APPARATUS FOR X-RAY PHASE CONTRAST IMAGE AND X-RAY COMPUTED TOMOGRAPHY SYSTEM |
摘要 |
<p>A source grating for X-rays and the like which can enhance spatial coherence and is used for X-ray phase contrast imaging is provided. The source grating for X-rays is disposed between an X-ray source and a test object and is used for X-ray phase contrast imaging. The source grating for X-rays includes a plurality of sub-gratings formed by periodically arranging projection parts each having a thickness shielding an X-ray at constant intervals. The plurality of sub-gratings are stacked in layers by being shifted.</p> |
