Abstract
Multiple elements of a blow-molded, integral patient support surface each include a synthetic sheet-like patient support element and an underlying synthetic corrugated reinforcing element spaced from the support element. When loaded, the patient support element engages the corrugated reinforcing element which resists deflection and rigidifies the surface. The corrugation angulation and the combined wall thicknesses of the flat support and corrugated reinforcing elements in a predetermined are are selected to provide an effective combined wall thickness within F.D.A. attenuation standards, yet still provide sufficient rigidity and aberration-free x-rays. An adjustable x-ray plate cassette is disclosed.
