ABSTRACT:
A body board is provided having upper and lower plastic components defining an outer plastic shell having a hollow interior. The underside of the plastic shell defines a pair of runners which serve to space handholds disposed about the periphery of the body board from the ground on which the body board rests. A fiberglass reinforcement structure having upper and lower sheets is disposed within the hollow interior. The fiberglass sheets are bent or curved across the width of the body board to provide increased structural support for resistance to deflection or sagging of the body board when supporting a patient. The thickness of the upper and lower plastic shell components and the thickness of the upper and lower sheets of the fiberglass reinforcement structure are substantially uniform over a central x-ray region. Also, none of the upper and lower plastic shell components or the upper and lower fiberglass sheets extend vertically over any portion thereof disposed within the central x-ray region. Hence, x-rays passed through the x-ray region of the body board are absorbed by the body board substantially uniformly, without producing any lines of high density on x-ray film. The x-ray region may include the runners, and no lines of high density are realized at the runners despite the increased thickness at the runners. Identifying indicia may be formed in the underside of the outer plastic shell by a manner in which the indicia do not produce high density images on x-ray film.
