Claims8
A radiological assembly, including:
- a radiological insert with a central portion and a peripheral portion, the central portion being relatively thinner and the peripheral portion being relatively thicker;
- an encapsulation around the radiological insert, one wall of the encapsulation including a channel into which the peripheral portion of the radiological insert extends, the one wall further including a plateau portion of increased thickness, bounded by the channel, facing the central portion of the radiological insert;
- and
- wherein the central portion of the radiological insert includes an upwardly extending convex upper surface which extends above the peripheral portion and a substantially planar lower surface, wherein the peripheral portion of the radiological insert extends below the substantially planar lower surface of the central portion.
