Abstract
The present invention provides a surgical drape adapted to cover either end of a C-arm-type x-ray machine having a laser targeting device mounted thereon. The surgical drape is made of an x-ray-transparent material, such as plastic, and includes a transparent window made of a material that does not diffuse or diffract a laser beam, such as an acetate film. The transparent window is preferably delineated from the main, plastic sheet of the surgical drape by a colored indicator. The indicator may be, for example, a colored band surrounding the window. Alternatively, the transparent window may itself be colored. In this case, the color chosen is matched to the wavelength of the laser beam so as to allow transmission of the laser beam yet filter out other wavelengths of light. The surgical drape is preferably shaped like a bag to fit over the end of the x-ray machine's C-arm.
