Diffraction-enhanced imaging (DEI) has high sensitivity and a wide dynamic range of density and thus can be used for fine imaging of biological and organic samples that include large differences in density. A fast DEI method composed of continuous fast sample rotations and slow analyzer crystal scanning was developed to shorten the measurement period. Fine sectional images of a biological sample were successfully obtained within a half measurement period of the conventional step-scanning method while keeping the same exposure time. In addition, a fine three-dimensional image of a rat tail was obtained with a 375 s measurement period.
衍射增强成像（DEI）具有很高的灵敏度和密度的宽动态范围，因此可用于包括密度差异较大的生物和有机样品的精细成像。开发了一种由连续快速样品旋转和缓慢分析器晶体扫描组成的快速 DEI 方法，以缩短测量周期。在保持相同曝光时间的情况下，在常规分步扫描方法的一半测量时间内成功获得了生物样品的精细截面图像。此外，还使用 375 秒的测量周期获得了老鼠尾巴的精细三维图像。
