Computed Radiography (CR) provides the digital equivalent of the conventional X-ray film while simultaneously providing the enormous advantages that consumables are virtually eliminated and the time to image is reduced considerably.
In addition the digital images can easily be archived and shared freely with other users. We emphasize the easy work flow and the ability to optimize the images by means of image software, thereby assuring improved analyses.
The CR technology consists of a 3-step process. The Image (storage) Plate (IP) is exposed with X-ray or Gamma radiation, which causes the IP phosphor layer in the plate to store the X-ray image.
During the reading process of the plate in the scanner, a focused laser beam triggers the release of the stored X-ray image data in the form of visible light.
The emitted light is captured and detected, then converted into electrical signals which are digitized and finally displayed as digital images on the monitor of the associated computer.
The internal in-line eraser purges the residual data from the IP, which is then ready for the next exposure.is CR? How does it work?
DURR NDT is the first worldwide company that has developed a 12,5μm laser spot scanner that, with correspondingly high resolution phosphor storage imaging plates, has met all of the stringent requirements of EN 14784 and ASTM 2446.
The combination of high resolution image plates and this HD-CR device achieves the unique Basic Spatial Resolution of 40μm over all system classes for the first time.
With the purchase of a HD-CR 35 NDT you decide for a perfect device for weld seam inspection. Furthermore, the HD-CR 35 NDT with its stepless adjustable laser reading resolution, is the perfect companion for those applications requiring lesser resolution capability.

Software X-vizor is running with most common versions of WINDOWS (XP, VISTA, 7) and allows to control the scanner for reading the plates, as well as make processing of the images on a computer. Key features of the software:
• 16-bit input level;
• filtering and image enhancement, archiving;
• common formats: JPEG, TIFF, BMP.
• Saving the act consistency of the complex operator;
• manual or automatic calibration of the scanning plate;
• calibration standard, which allows to evaluate the size of defects with high accuracy.
• built-in algorithms for automated search of defects with customizable thresholds.
Specially for using rigid plates was designed stationary scanner CR 43 NDT
