Computer assisted tomography in orbital disease.

Abstract

Computer assisted tomography (CAT) in the transverse axial plane, a fundamentally new method of x-ray diagnosis, was developed from I967 to 1972 by G. N. Hounsfield (I973) at the Central Research Laboratories of E.M.I. Ltd. Clinical evaluation of this technique by J. Ambrose (I973) at Atkinson Morley's Hospital has indicated the enormous value of the investigation in patients with intracranial disease. Minor modifications of the exam- ination technique have enabled us to study the orbit, and this report presents our initial findings.
