positioning a patient on an inflatable patient support, wherein the inflatable patient support comprises a top panel defining a first perimeter, a bottom panel defining a second perimeter, and an internal wall, wherein the top panel and the bottom panel define a substantially rectangular outer perimeter in a deflated state, wherein the top panel and the bottom panel define a first arm section and a second arm section in an inflated state, wherein the second perimeter of the bottom panel is coupled to the first perimeter of the top panel, wherein the internal wall is coupled between the top panel and the bottom panel to define a first chamber and a second chamber, wherein the internal wall defines at least one passage therethrough, wherein the at least one passage allows fluid communication between the first chamber and the second chamber, wherein the first chamber and the second chamber are inflatable, and wherein the top panel and the bottom panel define a substantially flat profile in a deflated state and a rounded profile configured to provide lateral stability in the inflated state;
coupling an inflation device to the first chamber of the inflatable patient support; providing air flow from the inflation device to the inflatable patient support, wherein the first chamber of the inflatable patient support is inflated at a first rate by air flow from the inflation device and the second chamber is inflated at a second rate by air flow from the first chamber through the at least one passage defined in the internal wall, wherein the first chamber is substantially inflated prior to inflation of the second chamber, wherein the first chamber includes the first arm section and the second arm section, and wherein the first arm section and the second arm section are configured to position a patient in the center of a patient seating area defined between the first arm section and the second arm section when the first arm section and the second arm section are inflated, and wherein the patient seating area is defined by a shape and perimeter of a portion of the top panel and the bottom panel only in the inflated state.
13. The method of claim 12 , wherein positioning the patient on the inflatable patient support comprises positioning the patient on a tongue extending from one of the first perimeter or the second perimeter.
14. The method of claim 13 , wherein prior to positioning the patient on the inflatable patient support, the method comprises positioning the patient support on an imaging table.
15. The method of claim 12 , wherein coupling the inflation device to the first chamber comprises coupling the inflation device to an inlet valve formed in one of the top panel or the bottom panel, wherein the inlet valve provides fluid communication between the inflation device and the first chamber.
16. The method of claim 15 , wherein the inlet valve is configured to provide one-way air flow from the inflation device to the first chamber.
