报告了使用 MIRRORCLE-6X 记录的放大 X 射线图像的高质量方面。 MIRRORCLE-6X具有放大投影X射线成像、微米级X射线源点、宽辐射发射角、X射线光谱范围从10 keV到6 MeV、自然折射衬度成像和高通量输出，天生适合硬X射线成像。当使用 25 微米棒电子靶生成时，以 11 倍几何放大倍率生成的图像显示出急剧增强的边缘效应。与吸收对比度图像相比，由于折射，图像对比度增强了 2 倍。通过对图像进行边缘增强，使植入人体胸部模型中的仿肿瘤清晰可见。使用硬 X 射线成像时，由于折射对比的自然结果，软组织变得高度可见。作者相信 MIRRORCLE 提供的新颖成像使其成为医学诊断的优质仪器。
The high-quality aspects of magnified X-ray images recorded using MIRRORCLE-6X are reported. MIRRORCLE-6X is inherently suitable for hard X-ray imaging owing to its magnified projection X-ray imaging, micrometre-size X-ray source point, wide radiation emission angle, X-ray spectrum ranging from 10 keV to 6 MeV, natural refraction contrast imaging and high flux output. Images produced with 11x geometrical magnification display a sharply enhanced edge effect when generated using a 25 microm rod electron target. Image contrast is enhanced 2x owing to refraction when compared with absorption contrast images. An imitation tumour implanted in a human chest phantom was made clearly visible by using edge enhancement on images. Soft tissue becomes highly visible as a natural consequence of refraction contrast when using hard X-rays for imaging. The authors believe that novel imaging provided by MIRRORCLE makes it a superior instrument for medical diagnosis.
