## Abstract

An inflatable mattress includes a top panel, a bottom panel, and a side panel coupled between a perimeter of the top panel and a perimeter of the bottom panel. The side panel defines a cutout sized and configured to receive a headrest therein. The top panel defines a fabric section extending over the cutout.

## Claims

### Claim 1

An inflatable mattress, comprising:
a top panel;
a bottom panel; and
a side panel coupled between a perimeter of the top panel and a perimeter of the bottom panel, the side panel defining a cutout sized and configured to receive a headrest therein, wherein the side panel comprises an inlet opening sized and configured to couple to an air supply hose.

### Claim 2 (depends on 1)

The inflatable mattress of claim 1, wherein the side panel defines a first sidewall and a second sidewall extending from the perimeter of the top panel to a rear wall defined by the side panel, and wherein the first sidewall, the second sidewall, and the rear wall define the cutout.

### Claim 3 (depends on 2)

The inflatable mattress of claim 2, wherein the perimeter of the bottom panel defines an opening sized and configured to match the cutout.

### Claim 4 (depends on 2)

The inflatable mattress of claim 2, wherein the top panel includes a fabric section extending over the cutout.

### Claim 5 (depends on 2)

The inflatable mattress of claim 2, wherein the first and second sidewalls extend from the perimeter of the top panel to the rear wall at an angle such that the cutout defines a first width at a proximal end and a second width at a distal end.

### Claim 6 (depends on 5)

The inflatable mattress of claim 5, wherein the first width is greater than the second width.

### Claim 7 (depends on 1)

The inflatable mattress of claim 1, comprising a plurality of handles coupled to one or more of the top panel, the bottom panel, or the side panel.

### Claim 8 (depends on 1)

The inflatable mattress of claim 1, wherein one or more of the top panel, the bottom panel, or the side panel comprise a single-use panel.

### Claim 9

An inflatable mattress, comprising:
a top panel;
a bottom panel; and
a side panel coupled between a perimeter of the top panel and a perimeter of the bottom panel, the side panel defining a cutout sized and configured to receive a headrest therein, wherein the bottom panel defines a plurality of perforations defined through a thickness of the bottom panel.

### Claim 10

An inflatable mattress, comprising:
a top panel having a first perimeter;
a bottom panel having a second perimeter coupled to the first perimeter, wherein the first perimeter and the second perimeter define a recess sized and configured to receive a headrest therein;
a fabric section coupled to the top panel and extending over the recess; and
an inlet opening coupled to one of the top panel or the bottom panel, wherein the inlet opening is sized and configured to couple to an air supply hose.

### Claim 11 (depends on 10)

The inflatable mattress of claim 10, comprising a plurality of handles coupled to one or more of the top panel, the bottom panel, or the side panel.

### Claim 12 (depends on 10)

The inflatable mattress of claim 10, wherein the recess is tapered such that the recess defines a first width at a open end and a second width at a closed end.

### Claim 13

A method of transporting a patient for medical imaging, comprising:
positioning a patient over an inflatable mattress, the inflatable mattress including a top panel, a bottom panel, and a side panel coupled between a perimeter of the top panel and a perimeter of the bottom panel, wherein the side panel defines a cutout sized and configured to receive a headrest therein;
inflating the inflatable mattress;
positioning the inflatable mattress on a medical imaging table, wherein a headrest of the imaging table is positioned within the cutout;
deflating the inflatable mattress, wherein a head of the patient is supported by the headrest of the imaging table when the inflatable mattress is deflated; and
acquiring one or more medical images of the patient.

### Claim 14

An inflatable mattress, comprising:
a top panel having a first perimeter;
a bottom panel having a second perimeter coupled to the first perimeter, wherein the first perimeter and the second perimeter define a recess sized and configured to receive a headrest therein, wherein the bottom panel defines a plurality of perforations defined through a thickness of the bottom panel; and
a fabric section coupled to the top panel and extending over the recess.

### Claim 15 (depends on 13)

The method of claim 13, comprising, prior to deflating the inflatable mattress, coupling the inflatable mattress to the medical imaging table using one or more straps coupled to the inflatable mattress.

### Claim 16 (depends on 13)

The method of claim 13, wherein the bottom panel of the inflatable mattress includes a plurality of holes defined therethrough, and wherein positioning the inflatable mattress on the medical imaging table comprises sliding the inflatable mattress on the medical imaging table.

### Claim 17 (depends on 13)

The method of claim 13, comprising re-inflating the inflatable mattress, wherein the head of the patient is not supported by the inflatable mattress when re-inflated.

### Claim 18 (depends on 13)

The method of claim 13, wherein the top panel of the inflatable mattress includes a fabric section extending over the cutout, and wherein the fabric section is received within the headrest of the imaging table.
