Abstract

Disclosed herein are representative embodiments of methods, apparatus, and systems for performing radiography analysis. For example, certain embodiments perform radiographic analysis using mixed variable computation techniques. One exemplary system comprises a radiation source, a two-dimensional detector for detecting radiation transmitted through a object between the radiation source and detector, and a computer. In this embodiment, the computer is configured to input the radiographic image data from the two-dimensional detector and to determine one or more materials that form the object by using an iterative analysis technique that selects the one or more materials from hierarchically arranged solution spaces of discrete material possibilities and selects the layer interfaces from the optimization of the continuous interface data.

First claim

What is claimed is:

1. A radiographic analysis method performed by computing hardware, the method comprising:
receiving radiographic image data of a spherically or cylindrically symmetric object;
performing a linear inversion of data derived from the radiographic image data;
establishing an initial estimate for an interface location of one or more layers of the object;
determining the interface location for the one or more of the layers of the object and identifications of o…
