What is Computed Radiography?

How does it work?

Computed Radiography (CR) is the production of a digital image by using a Phosphor Imaging Plate (IP) in place of conventional film.

IPs are reusable

No dark room or chemicals required

Exposure and process times reduced

Easy work flow and image optimisation with EOD-Tec software

Simple to share digital information and archive

The CR technology consists of a 3-step process

The Imaging (storage) Plate (IP) is exposed with X-ray or Gamma radiation, which causes the IP phosphor layer in the plate to store the image.

During the reading process of the plate in the scanner, a focused laser beam triggers the release of the stored image data in the form of visible light.

The emitted light is detected, captured and converted into electrical signals which are digitized and finally displayed as a digital image on the PC monitor.

The internal in-line eraser purges the residual data from the IP, which is then ready for the next exposure.

What is important in deciding to use CR?

Especially in the IED / EOD area, with a variety of object, the size of the storage plate, and therefore the available exposure area, is very important. Images must gather all the information in minimal time so that the additional disposal steps can be executed as fast as possible. Mobility and portability are important.

Rapid deployment to the site, with consideration and awareness of the surroundings and its terrain is critical for a successful mission.

Ultimately, the specific situation the bomb squad finds itself in, must be considered. The software must be simple, and has to produce a reliable result on which security based decisions can be made in shortest time.
