Comparison of image layer location among panoramic machines of the same manufacturer.
The central plane of the image layer was located in several panoramic machines of the same manufacturer by making radiographs of a spherical test object placed in different positions. A round image indicated that the test object was at the central plane. The inconsistency of the location of the central plane in machines tested indicates the need for establishing a quality assurance test to verify image-layer location before patient exposure.
