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 11× geometrical magnification display a sharply enhanced edge effect when generated using a 25 µm rod electron target. Image contrast is enhanced 2× 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.
