The present invention relates to a structurally rigid, X-ray translucent backboard for transporting an injured person from the scene of an injury to a treatment center. The backboard comprises a planar top side which contacts the patient and a bottom side forming a single curvilinear shape that provides structural support to the planar top side. A hollow, foam filled core formed between the planer top side and the curved bottom side helps provide sufficient X-ray translucence and structural support to the backboard.

1. A patient supporting device comprising:a) a unitary, rigid backboard having a length and a width and including a top side and a bottom side, said top side having a planar surface and said bottom side having a single continuous curvilinear shape which maintains substantially the same cross-section along substantially the length of said backboard and that provides structural support to said top side while providing substantial x-ray translucence to said backboard.2. The patient supporting device according to claim 1 wherein said single continuous curvilinear shape is formed by a curve comprising two peaks placed at equidistant locations from a trough.3. The patient supporting device according to claim 2 wherein said curve formed between said two peaks and said trough is defined by a 45 degree angle from the bottom of said trough to the top of each of said two peaks.4. The patient supporting device according to claim 2 wherein said curve between said two peaks and said trough is at an angular orientation that permits said patient supporting device to be substantially X-ray translucent.5. The patient supporting device according to claim 4 wherein said angular orientation is in a range between 30 degrees and 60 degrees from the bottom of said trough to the top of each of said two peaks.6. The patient supporting device according to claim 1 wherein said backboard has a rate of deflection of less than two inches when carrying a one hundred pound load or less and supported at two points.7. The patient supporting device according to claim 1 wherein said backboard has a rate of deflection of less than 0.2 inches when carrying a three hundred pound load or less and supported at four points.8. The patient supporting device according to claim 1 wherein said backboard has a rate of deflection of less than 0.3 inches when carrying a four hundred pound load or less and supported at four points.9. A patient supporting device comprising:a) a unitary, rigid, X-ray translucent member having a length and a width with a top side, a bottom side, and opposing side portions that define a hollow interior portion, said bottom side forming a single curvilinear shape that maintains substantially the same cross-section along substantially the length of said translucent member and said top side having a planar surface and said hollow interior portion containing an X-ray translucent material.10. The patient supporting device according to claim 9, wherein said hollow interior portion includes at least two structural supporting regions that contain a greater quantity of said X-ray translucent material than the remainder of said hollow interior portion.11. The patient supporting device according to claim 9 wherein said rigid, X-ray translucent member includes at least one integral handle attached to said rigid X-ray translucent member.12. The patient supporting device according to claim 9 wherein said single curvilinear shape disperses said X-ray translucent material into at least two structural supporting regions.13. The patient supporting device according to claim 12 wherein said structural supporting regions enable said rigid, X-ray translucent member to have a rate of deflection of less than two inches when carrying a one hundred pound load or less and supported at two points.14. The patient supporting device according to claim 12 wherein said structural supporting regions enable said rigid, X-ray translucent member to have a rate of deflection of less than 0.2 inches when carrying a three hundred pound load or less and supported at four points.15. The patient supporting device according to claim 12 wherein said structural supporting regions enable said rigid, X-ray translucent member to have a rate of deflection of less than 0.3 inches when carrying a four hundred pound load or less and supported at four points.16. A method of transporting and X-raying a patient comprising the steps of:a) providing a unitary, rigid, X-ray translucent backboard having a length and a width comprising a planar top side and a bottom side having a single continuous curvilinear shape which maintains substantially the same cross-section along substantially the length of said backboard and that provides structural support to said planar top side,b) placing a patient on said planar top side;c) transporting said patient to an X-ray machine; andd) obtaining a medically acceptable X-ray of the patient while said patient is still located on said planar top side.17. The method according to claim 16 wherein said single curvilinear shape defines at least two structural supporting regions that disperse an X-ray translucent material within an interior core defined by said X-ray translucent backboard.18. The method according to claim 16 wherein said rigid, X-ray translucent backboard has a rate of deflection of less than two inches when said patient weighs 100 pounds or less and said rigid, X-ray translucent backboard is supported at two points.19. The method according to claim 16 wherein said rigid, X-ray translucent backboard has a rate of deflection of less than 0.2 inches when said patient weighs 300 pounds or less and said rigid, X-ray translucent backboard is supported at four points.20. The method according to claim 16 wherein said rigid, X-ray translucent backboard has a rate of deflection of less than 0.3 inches when said patient weighs 400 pounds or less and said rigid, X-ray translucent backboard is supported at four points.
