Dual Energy Volumetric X-ray Tomographic Sensor for Luggage Screening

Abstract

Various imaging sensors have been used for luggage screening for explosive detection. Recent developments in dual energy X-ray volumetric computed tomography (CT) have demonstrated its advantages over other imaging sensors for luggage screening. These advantages include higher performance in automatic explosive detection, effectiveness for weapon detection, superior visualization capabilities, and automatic visual cueing for on-screen threat resolution. In this paper, we describe the performance of one such X-ray sensor using our transportation security administration (TSA) certified dual energy volumetric CT for explosive detection.
