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.
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因其放大投影X射线成像、微米级X射线源点、宽辐射发射角、10 keV至6 MeV的X射线光谱、自然折射对比成像和高通量输出，本质上适用于硬X射线成像。当使用25微米棒状电子靶产生时，具有11倍几何放大率的图像显示出明显增强的边缘效应。与吸收对比图像相比，由于折射，图像对比度提高了2倍。通过对图像进行边缘增强，植入人体胸部模型中的模拟肿瘤清晰可见。当使用硬X射线进行成像时，由于折射对比，软组织自然变得高度可见。作者认为，MIRRORCLE提供的新型成像使其成为医学诊断的卓越仪器。
