Abstract
A device for positioning the spinal column of a patient with respect to exposure control devices behind a chest X-ray film sheet has a light source generating a plane of light bearing a fixed relationship to the exposure control devices. The plane forms a luminous line on the patient when the patient steps in the path of the plane which may be used for positioning as by placing the patient's spinal column along the line. The other planes of light may be used to define the edges of the X-ray film sheet.
