Disclosed is a shielding system for customized shielding of a patient or an operator from X-rays generated from a gantry. The shielding system is mounted on the gantry. The system has a rail that is arcuately movable in relation to gantry-mounted foundational blocks with apertures that receive a proximal section of the rail. Protective curtains are suspended from intermediate and/or distal sections of the rail.
