Abstract
Method and apparatus for imaging using penetrating radiant energy provides a resulting image with elements of intensity related to atomic number. A penetrating radiant energy source is used for generating a flying spot. A first detector is located to be responsive to transmitted energy, e.g. the flying spot traverses the first detector. A second detector is located substantially coplanar with the first detector to be responsive to scattered energy, as the flying spot scans a target. The signals produced by the first and second detectors are combined to produce an image array having elements of intensity related to atomic number. A method and apparatus for non-invasively measuring density using the apparatus already recited, is also disclosed.
