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. The company is owned by OSI Systems. [1]
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.
They're all citing a new report that says a full-body scanner used by the Transportation Security Administration up until just last year could easily be tricked - allowing guns, knives and even ...
X-ray detection is also used to detect related components such as detonators, but this can be foiled if such devices are hidden inside other electronic equipment. [ 10 ] Adding marker substances (X-ray opacifiers) to commercial explosives is also an option.
An X-ray generator generally contains an X-ray tube to produce the X-rays. Possibly, radioisotopes can also be used to generate X-rays. [1]An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.
The first (ultra-low-dose backscatter X-ray) full body security scanner was developed by Dr. Steven W Smith, [5] [6] who developed the Secure 1000 whole body scanner in 1992.
