Abstract
Abstract An arrangement for protecting portions of a person, specifically the gonads, of a person being X-rayed, for use in conjunction with diagnostic X-ray appliances provided with an anti-diffusing screen and a light visor to indicate the object field of the X-rays. The arrangement includes a mounting device which is detachably attachable to the anti-diffusion screen and a shadow-casting plate movably supported by the mounting device. The shadow-casting plate is supported at a support plate made of a material permeable to light and X-rays. The mounting device includes a mounting frame with two spaced longitudinal legs and two spaced cross legs attached to the longitudinal legs, with each of the cross legs including a longitudinal slot for accommodating movable support of the support plate for the shadow-casting device. Leaf springs are provided in the longitudinal slots for holding the support plate in respective adjusted positions, with the support plate being movable both laterally and longitudinally in the slots.
