Computed Radiography (CR)
James Fisher NDT (JF NDT) can offer customers computed radiography (CR) inspection techniques.
CR is an indirect image capture method that uses Storage Phosphor Imaging Plates (IP) instead of conventional film. After image capture the reusable IP is processed through a scanner which reads and digitizes the analog X-Ray signal for interpretation in the viewing software. All materials that could be inspected using standard film based radiographic techniques can be inspected using CR.
JF NDT has experience working with a wide range of industries, such as the aerospace and automotive industries. All JF NDT digital radiography staff are third party trained and approved in accordance with NAS 410 and EN4179 standard. JF NDT is accredited to ISO/IEC 17025:2017 and approved by Nadcap, Boeing and Rolls Royce PLC and was the first test facility in the world to be issued with NADCAP accreditation for computed radiography.
Some of the advantages of using computed radiography (CR) include:
- CR IP’s are very flexible, they can be used inside castings or pipe similar to a film exposure
- The CR scanner allows for scanning resolution down to 25 micron equivalent to a D4 film
- Image acquisition is much faster than conventional film radiography, which results in faster turnaround times
- CR can inspect a larger dynamic range of thicknesses in one exposure, in contrast to conventional film based radiography, which may necessitate a different exposure or multiple film speeds in one exposure to cover a wide range of thicknesses
- Images can be stored on disk or transferred to multiple people for off-site review
- Prices will not be forced upwards by the increasing costs of both film and treatment of film processing effluent, and as no silver based film or chemicals are needed there are no waste products, so this is better for the environment.
