Development of Transformative Image Reconstruction Capabilities for Radiological Source Characterization

Topics: Nuclear Science and Technology Nuclear Security Science and Technology

Problem Statement

Two approaches for determining unknown (shielded) radiological objects are quantitative imaging and inversion based on spectral data.  Each of these has weaknesses – quantitative imaging lacks rigorous uncertainty quantification and spectral-based inversion methods rely on a number of simplifying assumptions. 

Technical Approach

By combining measured imaging and spectral data, we take the best qualities from each to make more accurate object reconstructions and uncertainty quantification. 

Benefit

The combination of imaging and spectral data allows us to remove many simplifying assumptions, obtain more accurate results, and perform rigorous uncertainty quantification.
