In general, it can be difficult and time consuming to mount X-ray shields or filters on an X-ray machine. An even more serious difficulty is that of effectively masking all but a specific area. A relatively effective X-ray shielding support, which can be adjusted in any direction to mask all but a specific area includes an apertured base plate for mounting on the machine to define a frame around the collimator aperture of the machine, a variety of spacers for mounting on the base plate, and filter holders for mounting on at least one of the base plate and spacers. The spacers and filter holders are magnetic to make interconnection of the elements quick and easy.
