Apparatuses for assisting patient movement to/from a gurney to/from a patient handling system are provided. In one embodiment, a bariatric overlay is provided that includes a flexible top pallet and a rigid bottom pallet. A bladder resides between the flexible top pallet and the rigid bottom pallet. When actuated, the bladder expands and props up the flexible top pallet. The flexible top pallet, rigid bottom pallet, and bladder are made of a material translucent to an imaging modality. In various embodiments, the shape of the rigid bottom pallet is similar to the shape of a scanning bed of the patient handling system. For example, when the shape of the scanning bed is concave the rigid bottom pallet is concave in shape also.
