过去几年，我们已经开发出使用光栅干涉仪在实验室 X 射线源上进行相衬成像，X 射线能量高达 28 keV。在这里，我们展示了在明显更高的 X 射线能量下记录的第一个相衬投影和断层扫描图像，这些图像是由在 100 kV 加速电压下运行的 X 射线管源产生的。我们发现测量的断层相位图像与表格数据非常吻合。相衬成像扩展到这种显着更高的 X 射线能量，开辟了该技术在医学和工业无损检测中的许多应用。
Phase-contrast imaging at laboratory-based x-ray sources using grating interferometers has been developed over the last few years for x-ray energies of up to 28 keV. Here, we show first phase-contrast projection and tomographic images recorded at significantly higher x-ray energies, produced by an x-ray tube source operated at 100 kV acceleration voltage. We find our measured tomographic phase images in good agreement with tabulated data. The extension of phase-contrast imaging to this significantly higher x-ray energy opens up many applications of the technique in medicine and industrial nondestructive testing.
