Abstract
Abstract A patient support table comprising a first patient support surface. The first patient support surface, in a preferred embodiment, is comprised of an x-ray translucent material such as carbon fiber. In a preferred embodiment, the top of the first patient support surface is for supporting a patient and is slightly concave. The patient support table also comprises a support, with the support being affixed to the first end of the first patient support surface at a first end of the support and extends beyond the third end of the first patient support surface. The support is affixed in such a manner that the first patient support surface may be interchanged with a second patient support surface, wherein the second patient support surface has all of the properties of the first patient support surface. The patient support table also comprises a base. The base is affixed to a second end of the support. The base allows positive and negative longitudinal tilt (Trendelenberg and reverse Trendelenberg), positive and negative lateral tilt, and height movement of the first patient support surface. The base provides a means for rigidly supporting the first patient support surface at a predetermined attitude and position.
