Process and apparatus for effecting slit radiography

摘要

A slit radiography assembly including an X-ray source, and X-ray detector and a slit diaphragm comprised of a plurality of sections juxtaposed in the longitudinal direction of the slit and coacting with controllable attenuation elements wherein: during scanning, a detection assembly includes a plurality of response sections cooperate with the X-ray detector to provide an electric signal representative of the intensity to control the attenuation elements during scanning at initial measuring exposure and subsequent radiographical exposure of the body.
