US Patent 8478016 Radiographic data interpretation

A method and apparatus are described for the collection and interpretation of radiographic data from an object scanned by a suitable radiation source. A radiation detector system is provided that is detecting and collecting spectroscopically resolved information. An object is scanned from a plurality of perspectives, and the resultant data from each perspective resolved into at least three spectroscopic energy bands. For each such resolved spectroscopic energy band an image analysis is performed to derive depth slicing to produce a series of output datasets each comprising a 2-D dataset of intensity information resolved to a single energy band and depth slice.
