[The internal structure of soft and bony tissues studied by X-ray refraction introscopy]

Whether X-ray refractional introscopy can be used to examine biological objects was studied. The characteristic emission of an X-ray tube provided refractional radiograms of the rat heart and limb, which allow one to make out the details of the structure of soft tissues and bones invisible on absorption radiograms under the same conditions. High-contrast refractional images of calcified formations were seen in the real-time mode when they were registered with a two-coordinate TV detector. The potentialities of the new method and medical diagnostic means are discussed.
