CT Studies for DHS

The Research Problem

The Department of Homeland Security (DHS) needed improved image processing algorithms for airport luggage screening, along with better characterization of signatures for homemade explosives and other bomb-making materials.

The Results

X-ray Scanner

Dr. Harry Martz has conducted X-ray signature studies that have provided DHS with critical information required to enhance improvised threat detection capabilities
