Computed Radiography (CR) is the production of a digital
image by using a Phosphor Imaging Plate (IP) in place of
conventional film.
Key advantaged of CR include:
? IP?s are re-usable
? No dark room or chemicals required
? Exposure and process times reduced
? Easy work flow and image optimisation with
D-Tect software
? Simple to share digital information and archive
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
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?
With film radiography the only variable is the film, with
CR we have different IP?s and the ability to adjust up to 4
paramaters within the scanner to optimise the image
quality to suit the required inspection task.
High definition Computed Radiography
D?RR NDT is the first company worldwide that has
developed a 12,5?m 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 40?m over all system classes for the
first time. (Certified by BAM)
Adjustable resolution
The HD-CR 35 NDT gives the user the choice to select
a 20 ?m scan resolution for weld inspection, or 100 ?m
scan resolution for a CUI application where speed and
a short exposure really are the prime requirements. The
stepless scan resolution ensures that the correct settings
can be set to suit the application and inspection needs
