Process and apparatus for scatter reduction in radiography

摘要

A process and apparatus for reducing detected radiation scatter in radiography. The process comprises interposing synchronized rotating radiation shields between the object being radiographed and the detector and desirably between the radiation source and the object. Openings in the shields are aligned in such a way as to permit primary radiation to pass to the detector while stopping most radiation scatter. The apparatus comprises the shields with openings, means for mounting the shields and means for rotating the shields at appropriate speeds.
