1. A device comprising:
a body that includes a plurality of openings and that forms one or more air spaces therein, wherein the plurality of openings and the one or more air spaces allow air to enter the body in a first direction, travel through the body in the first direction, exit the body in the first direction, enter the body in a second direction, travel through the body in the second direction, and exit the body in the second direction, wherein the first direction is orthogonal to the second direction, and wherein the body is inflatable; and
one or more breathable barriers positioned over at least some of the plurality of openings, wherein the one or more breathable barriers allow air to flow through the at least some of the plurality of openings into the one or more air spaces,
wherein the device is configured to position a patient in a bore of a magnetic-resonance-imaging device.
