Abstract
A patient support structure that employs fluid pressure to fluidize granular material for patient support. Fluidizable granular material is received within the structure atop a fluid diffuser surface. Separate plenum chambers are located below the diffuser surface with each plenum chamber being associated with valved fluid manifolds. Operators are associated with the valves and a control system for sequential or otherwise opening and closing of the valves to permit controlled fluidization of the granular material over a selected portion of the diffuser surface according to a predetermined arrangement.
