An apparatus for aligning a radiation source with an image receiver. The apparatus includes first and second light sources. The first light source is coupled to the image receiver and actuable to direct a first pattern of light toward the radiation source. The second light source is coupled to the image receiver and actuable to direct a second pattern of light toward the radiation source. The spatial relationship of the two patterns on or near the radiation source indicates a predetermined alignment position for the radiation source.
