Patent Number: 
Section: claims

1. An x-ray shielding system for customized shielding from x-rays generated by a gantry, the shielding system comprising:one or more foundational blocks, each block havinga bottom surface and an opposing top surface;a rail-receiving aperture that extends at least partially between the bottom surface and the opposing top surface;a detent defined by the top surface, the detent being configured to be in registration with a lug that extends radially from the rail so that upon registration, there is little or no movement of the rail in relation to the foundational block;the rail having a proximal section that is received by the rail-receiving aperture and a distal section that extends from the proximal section so that one or more radio-opaque curtains can be suspended from the distal section. 2. The shielding system of claim 1, further including:a knob that is received at an end of the distal section of the rail for constraining lateral movement of the one or more radio-opaque curtains along the distal section of the rail. 3. The shielding system of claim 1, wherein the rail-receiving aperture terminates at the top surface and the detents extend radially from the post-receiving aperture, the detents being configured to engage lugs that extend radially from the proximal section of the rail to preclude a twisting motion of the rail within an associated aperture when the proximal section is seated, thereby influencing rail positioning regardless of gantry orientation. 4. The shielding system of claim 1, wherein one rail orientation is a generally horizontal orientation. 5. The shielding system of claim 1, wherein one rail orientation is a forward orientation. 6. The shielding system of claim 1, wherein the rail can be twisted within the aperture so that the distal section of the rail extends horizontally regardless of gantry orientation. 7. The shielding system of claim 1, wherein there are two foundational blocks, each supporting one or more rails, each rail having a distal section extending horizontally, and the other rail having a distal section that lies in another orientation.
