The system’s scanning capabilities are illustrated on a phantom, a life-size dummy made of tissue-equivalent plastic, meaning it absorbs, transmits, and scatters x rays in a similar way to human tissue. Objects “concealed” beneath the dummy’s clothes -- a razor blade, powdered and plastic explosives, or a cell phone – are revealed in the scans. In the NIST and NAS studies, phantoms were used to assess the levels of backscattered x rays to operators and other bystanders. For full image of the phantom in the scanner, click here.
