  • Biological soft tissues are almost transparent to hard X rays and therefore cannot be investigated without enhancement with a contrast medium, such as iodine. On the other hand, phase–contrast X–ray imaging is sensitive to light elements1–8. This is because the X–ray phase shift cross section is almost a thousand times larger than the X–ray absorption cross section for light elements such as hydrogen, carbon, nitrogen and oxygen4,5. Hence, phase–contrast X–ray imaging is a promising technique… CONTINUE READING
