Submillimeter resolution CT scanning of orbital diseases.
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.
