     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 9 thereof, a new and improved examination table top embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the examination table top 10 of the instant invention is essentially arranged for mounting relative to an X-ray structure, of a type as indicated in U.S. Pat. No. 5,014,292, as well as the U.S. Pat. No. 5,048,071. The table top structure, as indicated in FIG. 1, is arranged to include spaced table rails 11 mounting a first torso cushion 12 in adjacency to a second torso cushion 13, with first and second shoulder cushions 14 and 15 spaced from the second torso cushion 13, having a mammary plate 16 oriented between the first and second shoulder cushions 14 and 15 and the second torso cushion 13, with a mammary plate 16 having a first side wall 17 in adjacency to the first and second shoulder cushions 14 and 15 oriented substantially at an oblique angle thereto and typically at an orthogonal relationship. A second side wall 18 is positioned in adjacency relative to the second torso cushion 13. First and second end walls 20 and 21 respectfully are mounted on opposed sides of the mammary plate 16, with first and second arcuate recesses 22 and 23 directed into the mammary plate from the respective first and second end walls 20 and 21, with the first and second arcuate recesses 22 and 23 directed from the top wall 24 through the bottom wall 25 of the mammary plate. 
     The modified mammary plate 16a, as indicated in FIG. 3, includes respective first and second L-shaped portions 26 and 27 defining the first arcuate recess 22 therebetween permitting adjustment of the first arcuate recess 22, and wherein third and fourth respective L-shaped portions 28 and 29 define the second arcuate recess 23 therebetween. A first slide rod 30 slidably mounts the first and second L-shaped portions 26 and 27, with a second slide rod 31 parallel to the first slide rod 30 arranged to slidably receive the third and fourth L-shaped portions 28 and 29 therebetween. A third slide rod 32 and a first control rod 35 orthogonally oriented relative to the first and second slide rods 30 and 31 extend between the first and third L-shaped portions 26 and 28, with the first control rod 35 having respective right and left hand threaded portions 36 and 37 threadedly directed into the respective third and first L-shaped portions 28 and 26, whereupon a spin wheel 38 fixedly mounted at an interface between the right and left hand threaded portions 36 and 37 permits ease of rotation of the control rod 35 to effect projection towards and away relative to one another of the first and third L-shaped portions 26 and 28. It should be noted that upon projection and displacement of the first and third L-shaped portions 26 and 28 relative to one another, the second and fourth L-shaped portions associated with respective first and third L-shaped portions move simultaneously and concurrently therewith. Fourth and fifth slide rods 33 and 34 are oriented parallel to the third slide rod 32 and the first control rod 35 and mounted slidably between the second and fourth L-shaped portions 27 and 29. 
     The FIG. 4 indicates the use of a cover plate 39 having parallel slots 40, with the parallel slots 40 oriented parallel between the third, fourth, and fifth slide rods 32, 33, and 34, wherein first guide pins 41 mounted to the first and second L-shaped portions 26 and 27 and second guide pins 42 mounted to the third and fourth L-shaped portions 28 and 29 are received within opposed ends of the slots 40. The cover plate 39 in this manner accommodates displacement of the pairs of L-shaped portions towards and away from one another in providing a cover plate to bridge the gapping and spacing of the L-shaped portions relative to one another. 
     The FIG. 5 indicates the use of a second control rod 43 directed between the first and second L-shaped portions 26 and 27 in addition to the first slide rod 30, with the second control rod 43 parallel to the first slide rod 30. The second control rod 43 includes respective second right and left hand portions 45 and 44 received within the respective received within the respective second and first L-shaped portions 26 and 27 to effect the control displacement of the first and second L-shaped portions 26 and 27 relative to one another to thereby effect simultaneous displacement of the third and fourth L-shaped portions 28 and 29 relative to one another. 
     The FIGS. 8 and 9 indicate the use of a pneumatic chamber 46 operative by pneumatic pump for inflation mounted between the first pair of L-shaped portions 26 and 27 relative to the second pair of L-shaped portions 28 and 29 to effect displacement of the L-shaped portions relative to one another, wherein a retraction spring mounted within the pneumatic chamber 46 is arranged to direct the pairs of L-shaped portions towards one another, as indicated. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
