U
Abstract:
A primary radiation diaphragm for X-ray examination devices has at least one pair of diaphragm plates movable in opposite directions relative to each other for gating an X-ray beam. The diaphragm plates are displaceably mounted in spaced planes and the respective adjustment limits are selected such that each diaphragm plate can selectively limit the X-ray beam with one of two edges disposed perpendicular to the path of adjustment movement. The edges may have different shapes for adapting the gated field to the shape of the body organ under examination.
