Patent ID: 7806591

Claim:
An apparatus for aligning an image receiver with a radiation source having a collimator light for aiming the source at an area to be imaged, the apparatus comprising: a first light source adapted to be coupled to the radiation source and actuable to direct a first beam of light toward the image receiver; a second light source adapted to be coupled to the radiation source and actuable to direct a second beam of light toward the image receiver; a reflector element adapted to be coupled to the image receiver and disposed to form, when placed in the path of both first and second light beams, reflected light that indicates the relative alignment of the image receiver to the radiation source; and a target adapted to be coupled to the radiation source to receive the reflected light, whereby the received reflected light on the target is visually observable by an operator to provide the operator a readily viewable indication of the relative alignment of the image receiver and the radiation source when the collimator light is aimed at the area to be imaged.
