The focal trough of the Autopan panoramic dental x-ray machine.
The focal trough of the Autopan machine was evaluated with a multiline test object. The width of the focal trough varied from 5.5 mm anteriorly to about 23 mm in the midramus area with 1.7 line pairs per millimeter of resolution. The focal trough covers most tooth position areas. The machine is capable of producing clinically acceptable radiographs in most clinic populations.
