CastScope

Casts and artificial limbs often contain metal components that cause archway metal detectors to alarm. Current security equipment is not designed to meet the needs of such travelers; so resolving these alarms has been difficult or impossible without time-consuming physical inspection and undue hardship on persons with special needs. Persons with artificial limbs, including some veterans, have been asked to remove their limbs at checkpoints for closer inspection and even baggage X-ray screening. These measures imposed undue stress, discomfort and delays.

project CastScope is the first system designed to screen persons with casts and prosthetic limbs for concealed weapons and contraband. CastScope permits rapid inspection of artificial limbs, casts and bandages "in-place" ensuring passengers' comfort and convenience. CastScope uses advanced backscatter X-ray technology to create a detailed image of the inside of a cast, making the screening process faster and more effective than current methods. CastScope can detect metal, non-metal, and liquid threats (or contraband) hidden in casts, prosthetic limbs and bandages.

CastScope was developed with input from the Transportation Security Administration (TSA), The American Orthotic and Prosthetic Association (AOPA) and The Amputee Coalition of America (ACA) to address the needs of persons with disabilities.

CastScope is compact and occupies no more space than a chair. The system is fully mobile, powered from a standard wall outlet, and can be installed in about 1 hour. CastScope is easy to use, has a touch-screen user interface and requires only a few minutes of instruction for basic operation. The X-ray dose from CastScope is equivalent to about 1 hour of dose from background radiation. The dose is substantially lower for prosthetic limb inspection. The system complies with radiation safety standard ANSI / HPS N43.17-2009 (general use/partial body system), and is certified to UL61010-1 safety standards.

At a time when aviation security is often perceived as becoming more difficult and cumbersome for the traveling public, CastScope addresses a security loophole while improving the security checkpoint experience for persons with disabilities.
