X-RAY INSPECTING METHOD AND X-RAY INSPECTING DEVICE

摘要

An X-ray inspecting method comprising the steps of setting the tube voltage of an X-ray tube to one that sets the difference in X-ray absorptance between a first X-ray propagating medium and a second X-ray propagating medium different in X-ray absorption power from the first X-ray propagating medium in a subject to 10% or smaller, applying an X-ray beam to the subject from the X-ray tube while being set to the above tube voltage, and detecting a transmission X-ray image having an X-ray refraction image formed, superposed on an X-ray absorption image reflecting the difference in X-ray absorption power between the first X-ray propagating medium and the second X-ray propagating medium, by the X-ray beam refraction at the interface surface between the first X-ray propagating medium and the second X-ray propagating medium in an area along the outline of the interface surface.
