M. Allmaras, D. Darrow, Y. Hristova, G. Kanschat, and P. Kuchment, "Detecting Small Low Emission Radiating Sources," Inverse Problems and Imaging Available Online 13 Dec 2010. To be published.


The article addresses the important for homeland security possibility of robust detection of geometrically small, low emission sources on a significantly stronger background. A technique of detecting such sources using Compton type cameras is developed and studied analytically and numerically, which is shown to have high sensitivity and specificity and also allows to assign confidence probabilities of the detection. The 2D case is considered in detail.
