Medical physics, 1999•Wiley Online LibraryThe low divergent x‐ray beam from the third‐generation synchrotron radiation source such
as SPring‐8 enables us to observe refraction of x rays that is in the range of microradians.
Under an experimental condition for which ray optics is a good approximation, we found that
the refraction produces a high‐contrast projection image of a mouse when it was recorded at
6.5 m behind the specimen. Especially, the lung is visualized far better than with the
conventional imaging which utilizes absorption of x rays. This is a promising new technique …
