A medial portion of the base can lie between the human patient and a table on which the human patient is supported. The arm pad can be positioned on a lateral portion of the base. A first barrier can be mounted to the base and can be positioned laterally intermediate the medial and lateral portions, the first barrier extending upwardly from the base to above the arm pad. A second barrier can be mounted to the lateral portion of the base and extend downwardly. The arm pad can include a radiopaque panel that is horizontal. ## Claims ### Claim 1 An apparatus for supporting an arm of a human patient during a medical procedure, the apparatus comprising: a base comprising a medial portion that is configured to lie between the human patient and a table on which the human patient is supported, and a lateral portion that extends laterally from the medial portion; an arm pad positioned on the lateral portion of the base, the arm pad extending longitudinally between first and second ends; a first barrier for shielding scatter radiation during the medical procedure, the first barrier mounted to the base and positioned laterally intermediate the medial and lateral portions thereof; and a second barrier for shielding scatter radiation during the medical procedure, the second barrier mounted to the lateral portion of the base and extending downwardly therefrom, wherein the arm pad comprises a proximal portion adjacent to the first end for supporting the arm of the human patient, a distal portion adjacent to the second end, a central portion arranged between the proximal and distal portions for supporting a hand of the arm, and a radiopaque panel for shielding scatter radiation during the medical procedure in the vicinity of the hand of the human patient, wherein an upper surface of the proximal portion is spaced above the lateral portion of the base, an upper surface of the central portion is spaced above the lateral portion of the base, and the upper surface of the central portion is substantially below the upper surface of the proximal portion, and wherein the first barrier extends upwardly from the base to a height above both the proximal and central upper surfaces of the arm pad. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the upper surface of the central portion is concave in shape to position the hand generally below the arm. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the first barrier is arranged longitudinally intermediate of the arm pad, the second barrier is arranged longitudinally intermediate of the arm pad, the central portion of the arm pad is arranged within a longitudinal extent of the first barrier, the central portion of the arm pad is arranged within a longitudinal extent of the second barrier, and the distal portion comprises an upper surface that is generally planar and horizontal. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the radiopaque panel is arranged in the central and distal portions of the arm pad, and the radiopaque panel is arranged horizontally and adjacent to the base. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the base is generally planar and formed at least partially of a substantially radiolucent material. ### Claim 6 (depends on 5) The apparatus of claim 5, wherein the medial portion of the base comprises a central aperture that is configured to be positioned underneath an abdomen of the human patient. ### Claim 7 (depends on 5) The apparatus of claim 5, wherein the lateral portion of the base extends longitudinally to support a length of the arm pad, and the lateral portion of the base extends laterally to support a width of the arm pad. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the arm pad is detached from the base. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the first and second barriers are each generally planar and formed at least partially of a substantially radiopaque material, and the first and second barriers are each arranged generally vertically. ### Claim 10 (depends on 9) The apparatus of claim 9, wherein the first barrier is mounted to the base by a flexible and resilient connection to permit manual adjustment of its position. ### Claim 11 (depends on 9) The apparatus of claim 9, wherein the second barrier is mounted to a lateral edge of the lateral portion, and the arm pad is positioned laterally intermediate the first and second barriers. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein the second barrier has a first vertical edge that is closer to the first end of the arm pad and a second vertical edge that is closer to the second end of the arm pad, and the second vertical edge is spaced apart laterally from the first vertical edge in a direction away from the arm pad. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein the second barrier comprises first and second planar portions that define the first and second vertical edges, respectively, and the second planar portion is joined to the first planar portion at an oblique angle. ### Claim 14 (depends on 1) The apparatus of claim 1, comprising a left wing that extends laterally from the medial portion opposite from the lateral portion, the left wing comprising an adjustable support that is configured to support the left arm of the human patient. ### Claim 15 (depends on 14) The apparatus of claim 14, wherein the support is pivotable about a longitudinal axis between a generally horizontal position and an upright position in which there is an acute angle between the support and the medial portion. ### Claim 16 (depends on 15) The apparatus of claim 15, comprising at least one hinge mechanism coupling the medial portion and the support that is configured to adjust the angle between the support and the medial portion. ### Claim 17 An apparatus, comprising: a base; a first barrier mounted to the base for shielding scatter radiation, the first barrier extending upwardly from the base; a second barrier mounted to the base for shielding scatter radiation, the second barrier extending downwardly from the base; and an arm pad on the base positioned laterally intermediate the first and second barriers, the arm pad comprising a proximal portion for supporting an arm of a human patient, a central portion for supporting a hand of the arm and having an upper surface being substantially below an upper surface of the proximal portion, and a radiopaque panel for shielding scatter radiation in the vicinity of the hand of the human patient, wherein the first barrier extends upwardly from the base to a height above both the proximal and central upper surfaces of the arm pad. ### Claim 18 (depends on 17) The apparatus of claim 17, wherein the upper surface of the central portion is concave in shape to position the hand generally below the arm. ### Claim 19 (depends on 18) The apparatus of claim 18, wherein the radiopaque panel is arranged in the central portion of the arm pad, and the radiopaque panel is arranged horizontally and adjacent to the base. ### Claim 20 A method of supporting an arm of a human patient, the method comprising: positioning a base to lie between the human patient and a table on which the human patient is supported, the base comprising a lateral portion that extends laterally from the table; placing the arm of the human patient on an arm pad that is positioned on the lateral portion of the base, the arm pad comprising a proximal portion comprising an upper surface for supporting the arm of the human patient, a central portion comprising an upper surface for supporting a hand of the arm being generally below the arm, and a radiopaque panel; shielding scatter radiation with the radiopaque panel in the vicinity of the hand of the human patient; shielding scatter radiation with a first barrier, the first barrier mounted to the base and positioned laterally intermediate the lateral portion and the human patient, the first barrier extending upwardly from the base to a height above both the proximal and central upper surfaces of the arm pad; and shielding scatter radiation with a second barrier, the second barrier mounted to the lateral portion of the base and extending downwardly therefrom.
