Abstract
An alignment device for use in mobile radiography. In contrast to prior practice in which a film cassette is placed on one side of the patient, an x-ray source on the other, and it is left to the skill of the technician to approximate the necessary alignment, the present invention assures consistent alignment much more precise than is typically achieved. The precise alignment allows regular use of a grid in mobile radiography which helps to prevent image deterioration caused by scattered radiation. The precise alignment is achieved by providing an adaptable physical connection which when in the deployed condition, accurately establishes both the distance between the focal spot and the film plane and the alignment of the grid with respect to the central ray.
