Digital/Computed Radiography
IXAR has invested in an emerging technology in the field of NDT which is Computed Radiography, enables the digital capture of an image by use of re-usable imaging plate (IP) which is coated with a phosphor layer, and when exposed to radiation is able to store resultant energy. The IP is then scanned using a laser scanner which results in the stored energy being released as ultraviolet light, the intensity related to amount of radiation received, these light intensities are then read by a laser and a digital image is generated. This image is stored as raw data, although the image can be enhanced to optimize the contrast, magnify and measure the component the initial image remains unchanged.
Computed Radiography DiagramComputed Radiography has many advantages over conventional radiography such as,
1) No expensive films to purchase
2) Quick results without processing of chemicals (more environmentally friendly)
3) Wider latitude to enable a greater thickness range to be captured on one exposure
4) Sharing of images electronically and easier storage (enhanced archiving and retrieval)
