Abstract
The work described has been obtained from the 160 x 160 matrix E.M.I. scanner at the Perth Medical Centre. The recorded data are presented as a computer printout of the mass absorption co-efficient values of the orbits in cells of 1.5 mm x 1.5 mm x 8 mm, referred to as μ values, as well as on a visual display, from which polaroid pictures are taken. In a six-month period, 47 patients had the orbits examined, and in the same interval 946 patients had the cranial contents scanned; any patient with visual loss without lateralizing proptosis had both orbit and cranium examined. There were 27 normal studies and 20 abnormal; the latter comprised six tumours, two trauma, three post-operative cases, three vascular, three demyelinating, one pseudo-tumour and two cataracts.
