Computerized Radiography Inspection

Computed radiography uses very similar equipment to conventional radiography except that in place of a film to create the image, an imaging plate made of photostimulable phosphor is used. The imaging plate could be used many times.

How ?

1) The phosphor screen is inserted into a soft or hard cassette (with or without lead) 2) A radiation pattern is exposed on the phosphor screen creating a latent image 3) The phosphor screen is then inserted into a phosphor scanner to be read 4) The phosphor screen is scanned and the digital image is displayed on the workstation monitor for review and evaluation 5) The phosphor screen is then erased and ready to be reused

Applications includes but not limited to:

  • On stream inspection
  • Weld inspection
  • Aerospace
  • Composite materials
  • Casting inspection
  • Security
