Abstract

Radiation is directed at an object, and radiation scattered by the object is sensed. An angular distribution of scatter in the sensed scattered radiation relative to a path of the radiation directed at the object is determined, and the angular distribution is evaluated. One or more atomic numbers, or effective atomic numbers, of materials composing the object is determined based on evaluating the angular distribution.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method comprising:
 directing radiation at an object;   sensing radiation scattered by the object;   determining an angular distribution of scatter in the sensed scattered radiation relative to a path of the radiation directed at the object;   evaluating the angular distribution; and   determining one or more atomic numbers, or effective atomic numbers, of materials composing the object based on evaluating the angular distribution.
