title: Submillimeter resolution CT scanning of orbital diseases.
abstract: continuous improvement in image quality produced by CT scanning has occurred since 1972 when the resolution element of the new EMI scanner was 3.0 X 3.0 X 12 mm. We are now working with a fourth generation machine with a resolution element of 0.75 X 0.75 X 2.0 mm. This hundred fold improvement in spatial resolution has had important clinical impact in analyzing diseases of the orbit.
