The CTX (Computer Tomography X-ray) is an explosive detection device, a family of x-ray devices developed by InVision Technologies in 1990 that uses CAT scans and sophisticated image processing software to automatically screen checked baggage for explosives.
Rapiscan X-ray backscatter scanner Advanced Technology (AT) X-ray systems for baggage scanning. Rapiscan Systems is an American privately held company that specialises in walk-through metal detectors and X-ray machines for screening airport luggage and cargo.
X-ray machines, CTX machines, high-resolution x-rays and ETDs are also used to scan checked bags. All checked baggage is always x-rayed at all major commercial airports. CATSA launched its Restricted Area Identity Card (RAIC) program in January 2007. RAIC is the world's first dual biometric access control system for airports. [29]
X-ray radiography is similar to gamma-ray radiography but instead of using a radioactive source, it uses a high-energy bremsstrahlung spectrum with energy in the 5–10 MeV range [8] [9] created by a linear particle accelerator (LINAC). Such X-ray systems can penetrate up to 30–40 cm of steel in vehicles moving with velocities up to 13 km/h.
The unidentified woman was flying from Los Angeles to Philadelphia Dec. 15 when the unusual contents of her bag alerted X-ray screeners, who opened it and came face to face with her alarming stash.
Specially designed X-ray machines using computed axial tomography can detect explosives by looking at the density of the items.. These systems that are furnished with dedicated software, containing an explosives threat library and false-color coding to assist operators with their dedicated threat resolution protocols. [ 9 ]
Luggage with meth-soaked shirts inside. ... But airport officers noticed that an X-ray machine had flagged her luggage for anomalies on Nov. 2 — and when they searched it, they allegedly found ...
This is the main reason it is commonly used in prisons and jails. However the current technology does not allow the dual-energy body scanning (and detecting the object by its atomic number like it is used in baggage or vehicle X-ray scanners) which could give the image the same detection effectiveness as regular black and white X-ray.
