Abstract

A radiation shield assembly is described, configured to block radiation emanating from a radiation source from reaching a user. Two shields are supported by a support arm, and are configured to rotate and translate relative to one another about the support arm's longitudinal axis. This allows the shield to be easily configured and reconfigured as necessary to visualize various parts of a patient's body via radiography.

Claims (61)

1 . A radiation shield assembly, comprising:

a first radiation shield panel configured to be positioned in a transverse orientation relative to an operating table;

a second radiation shield panel;

a third radiation shield panel; and

a vertical member positioned between and coupled to the first radiation shield panel and the second radiation shield panel,

wherein the second radiation shield panel is configured to rotate relative to the first radiation shield panel about a first vertical axis defined by the vertical member,

wherein the third radiation shield panel is configured to rotate relative to the first radiation shield panel about a second vertical axis, and

wherein each of the first radiation shield panel, the second radiation shield panel, and the third radiation shield panel is (i) composed of a rigid material, (ii) planar, and (iii) at least partially transparent to visible light.

2 . The radiation shield assembly of claim 1 wherein the first radiation shield panel is fixed against rotation relative to the second radiation shield panel and the third radiation shield panel about a horizontal axis extending within a plane defined by the first radiation shield panel and/or the second radiation shield panel.

3 . The radiation shield assembly of claim 1 wherein the third radiation shield panel is configured to rotate relative to the first radiation shield panel independently of the second radiation shield panel rotating relative to the first radiation shield panel.

4 . The radiation shield assembly of claim 1 wherein, in one configuration of the radiation shield assembly, the first radiation shield panel extends within a first vertical plane and the third radiation shield panel extends within a second vertical plane different than the first vertical plane.

5 . The radiation shield assembly of claim 1 wherein each of the second radiation shield panel and the third radiation shield panel has a substantially straight lower edge.

6 . The radiation shield assembly of claim 5 wherein the first radiation shield panel has a substantially straight lower edge.

7 . The radiation shield assembly of claim 1 wherein the first radiation shield panel and the second radiation shield panel are configured to be suspended entirely above a height of the operating table.

8 . The radiation shield assembly of claim 1 wherein the third radiation shield panel has a smaller surface area than the first radiation shield panel.

9 . The radiation shield assembly of claim 1 wherein the third radiation shield panel is not directly coupled to the vertical member.

10 . The radiation shield assembly of claim 1 wherein the vertical member includes a cylindrical rod.

11 . The radiation shield assembly of claim 1 wherein the first vertical axis and the second vertical axis are aligned.

12 . The radiation shield assembly of claim 1 , further comprising a support member coupled to an uppermost portion of the first radiation shield panel.

13 . The radiation shield assembly of claim 1 , further comprising a flexible radiopaque shroud coupled to a bottom edge of the first radiation shield panel.

14 . The radiation shield assembly of claim 1 , wherein each of the first radiation shield panel, the second radiation shield panel, and the third radiation shield panel has a radiopacity of about 1.0 mm lead equivalent.

15 . A radiation shield assembly, comprising:

a first radiation shield panel configured to be positioned in a transverse orientation relative to an operating table;

a second radiation shield panel;

a third radiation shield panel; and

a vertical member positioned between and coupled to the first radiation shield panel and the second radiation shield panel,

wherein the second radiation shield panel is configured to rotate relative to the first radiation shield panel about the vertical member,

wherein the third radiation shield panel is configured to rotate relative to at least one of the first radiation shield panel or the second radiation shield panel about a vertical axis,

wherein each of the first radiation shield panel, the second radiation shield panel, and the third radiation shield panel is (i) composed of a rigid material, and (ii) at least partially transparent to visible light, and

wherein the first radiation shield panel is fixed against rotation relative to the second radiation shield panel and the third radiation shield panel about a horizontal axis extending within a plane defined by the first radiation shield panel, the second radiation shield panel, and/or the third radiation shield panel.

16 . The radiation shield assembly of claim 15 wherein each of the first radiation shield panel, the second radiation shield panel, and the third radiation shield panel is planar.

17 . The radiation shield assembly of claim 15 wherein each of the second radiation shield panel and the third radiation shield panel has a substantially straight lower edge.

18 . The radiation shield assembly of claim 17 wherein the first radiation shield panel has a substantially straight lower edge.

19 . The radiation shield assembly of claim 15 wherein the third radiation shield panel is not directly coupled to the vertical member.

20 . The radiation shield assembly of claim 15 , further comprising a support member coupled to an uppermost portion of the first radiation shield panel.

21 . A radiation shield assembly, comprising:

a first radiation shield panel configured to be positioned in a transverse orientation relative to an operating table;

a second radiation shield panel;

a third radiation shield panel; and

a vertical member positioned between and coupled to the first radiation shield panel and the second radiation shield panel,

wherein the third radiation shield panel is coupled to the first radiation shield panel, and

wherein each of the first radiation shield panel, the second radiation shield panel, and the third radiation shield panel is (i) composed of a rigid material, (ii) planar, and (iii) at least partially transparent to visible light.

22 . The radiation shield assembly of claim 21 wherein the vertical member includes a hinge.

23 . The radiation shield assembly of claim 22 wherein the second radiation shield panel is configured to rotate relative to the first radiation shield panel about the hinge.

24 . The radiation shield assembly of claim 21 wherein the first radiation shield panel is fixed against rotation relative to the second radiation shield panel and the third radiation shield panel about a horizontal axis extending within a plane defined by the first radiation shield panel and/or the second radiation shield panel.

25 . The radiation shield assembly of claim 21 wherein an entirety of the first radiation shield panel, the second radiation shield panel, and the third radiation shield panel is rigid.

26 . The radiation shield assembly of claim 21 wherein:

each of the second radiation shield panel and the third radiation shield panel has a substantially straight lower edge, and

the third radiation shield panel has a smaller surface area than the first radiation shield panel.

27 . The radiation shield assembly of claim 21 , further comprising a common support structure including a vertically extending support arm configured to support the first radiation shield panel, the second radiation shield panel, and the third radiation shield panel.

28 . A radiation shield assembly, comprising:

a first radiation shield panel configured to be positioned in a transverse orientation relative to an operating table;

a second radiation shield panel;

a third radiation shield panel coupled to the first radiation shield panel, wherein the third radiation shield panel includes a surface area smaller than the first radiation shield panel; and

a vertical member positioned between and coupled to the first radiation shield panel and the second radiation shield panel without being directly coupled to the third radiation shield panel,

wherein the second radiation shield panel is configured to rotate relative to the first radiation shield panel about the vertical member,

wherein the third radiation shield panel is configured to rotate relative to at least one of the first radiation shield panel or the second radiation shield panel about a vertical axis,
