ABSTRACT:
An X-ray shielding apparatus (40) and an X-ray device incorporating such an apparatus are described. The apparatus (40) comprises a stationary member (94) having an aperture and one or more shielding members (96, 98) movable in relation to the stationary member (94) and made from an X-ray shielding material. The one or more shielding members (96, 98) define an X-ray passage (90) within the aperture that is smaller than the aperture. Movement of the one or more shielding members (96, 98) is restricted such that the one or more shielding members (96, 98) in each position relative to the stationary member (94) cover the aperture at least in an area outside the X-ray passage (90).
