Micro computed tomography is X-ray imaging in 3D, by the same method used in hospital CT scans, but on a small scale with massively increased resolution. It really represents 3D microscopy, where very fine scale internal structure of objects is imaged non-destructively.
In an open system-ray scanner may escape or leak out thus the operator must stay on a different room or operate the scanner from a distance, one example of this scanners is the human version or designed for big objects. On a closed system, an X-ray shielding is put around the scanner so the operator can put the scanner on a special table or desk.
There are two types of scanner set-ups; the first one is the x-ray source and detector which is typically the most stationary while the subject rotates for scanning. The second type is much more similar of a clinical CT scanner, a gantry based where the specimen or subject is stationary in space while the X-ray tube and detector rotates around it. But this scanner is mostly use for biomedical and other types of study which minute details is desired.
The military has been using this technology to utilize any properties like baggage, bags, cargos, or even vehicles for possible destructive materials or threat on public establishments. The operator is able to control the scanner and view the images hidden inside from a remote laptop workstation. Sophisticated easy to use software allows the operator to zoom, pan and process the image to be able to make a rapid and accurate assessment of any potential risk. This ‘state of the art’ technology provides safety and security on airports, public terminals, and other places from bombing terrorists, drug smugglers, etc. This can spot materials that more traditional systems such as transmission X-ray can miss including explosives, currency, and drugs. Combined with enhanced 3D visualization and simple to use image processing tools the operator is able to make fast and accurate decisions, thereby increasing output and decreasing the incidence of false alarms, or missed threats.
On airports and other transportation hubs, bomb attacks have increased over the past few years and illegal materials have slipped through security with the old-fashion process of checking baggage and mail boxes. Today, 3D X-ray scanner used has sub-millimeter image resolution and sophisticated image processing software that enable customs and security personnel to detect threat items and contraband including ammunition, weapons, IEDs, drugs, cigarettes, and alcohol.
Huge events across the world have also been a hotspot for hoax and real threats. Security strategies are now implemented to accommodate the large amount of attendees on the event without giving rise to intolerable queues during the event. A 3D X-ray scanner that is lightweight and easy to deploy is now being used as an additional strategy.
High security buildings and establishments are no exception for these dangerous threats. Security surrounding access to prisons, government offices, embassies, corporate headquarters and other high profile or high risk organizations has to be tightly controlled whilst minimizing inconvenience for employees working in, or visitors to, such places. 3D X-ray scanner provides a fast and effective screening on any items entering the site.
