Abstract
Evaluation of the EMI Scanner, an x-ray transverse axial tomograph, has shown that the unit provides numerical values which are linearly related to the 73 keV attenuation coefficient values with an agreement of better than one half of one per cent. Precision of these determinations has also been shown to be 0.5%. Independence of spatial location and accurate resolution of objects as small as 6 mm have been demonstrated. An adjacency effect at a bone-brain matter interface was measured. Radiation exposures arc comparable to those received in many diagnostic roentgenologic procedures.
