Abstract
A device and method for verifying positional alignment between a visible light beam and an x-ray beam by providing a radio-opaque body that is to be positioned in the center of the visible light beam in the x-ray field. The image of the radio-opaque body provides an indication of whether the position of the visible light beam is colinear and coincident with the central ray of the x-ray beam of an imaging system.
