Simple CT Scanner Calibration Artifact Released

Industrial computed tomography (CT) scanners can measure internal part features that are inaccessible to traditional measuring devices. X-ray CT systems are gaining in popularity with manufacturers as a non-destructive tool to accurately measure hidden features and as an alternative to traditional tactile CMMs for some measurement tasks.

Like other metrology tools, CT scanners require calibration.

Q-Mark has release a range of simple, low-cost, CT Scan Artifacts for CT scanner calibration.

The CT Scan Artifacts consists of twin ruby spheres bonded to a carbon fiber shaft.  After first using a calibrated CMM to measure the center-to-center sphere distance, the user then procedes to measure the same distance with the CT scanner. Any deviation from the CMM’s result can usually be adjusted with the scanner’s software.

Q-Mark manufacture four sizes of CT Scan Artifacts, with twin 2.0, 3.0 6.0 and 8.0 mm ruby spheres. The distance between spheres offered is 20.0, 30.0, 60.0, or 80.0 mm, respectively.
