SR X-ray imaging of lung cancer samples obtained on the eleventh day after implantation. (a) Phase-contrast SR image of normal lung tissue: venules (blue arrows) and air sacs (red arrows). (b) Absorption image of lung cancer: tumor boundary (green arrows). (c) Phase-contrast SR image of lung cancer: tortuous early cancer angiogenesis (white arrows) and the periphery region of the cancerous tissue (green arrows); air sacs (red arrow) and thickened alveolar walls (pink arrows).
