Abstract
An indicator for defining the relationship of a radiation beam to an object, such as a patient or associated apparatus, for example an X-ray film holder. The indicator includes a light source establishing a first light plane containing the beam and appliable to the object. A second light source establishes a second plane of light to contain the radiation beam or object. The intersection of the beams of light defines the radiation beam-object relationship.
