Nikon Metrology's Detector Evaluation Package offers automated analysis of image data with performance trend analysis. To help users of Nikon Metrology's X-ray CT systems to process-check their detector performance throughout service, the company has launched a monitoring kit in accordance with the globally accepted standard, ASTM E2737.
The ASTM E2737 Detector Evaluation Package is available to suit the range of Nikon Metrology’s X-ray CT inspection, metrology and large-envelope CT systems. All of the manufacturer’s X-ray sources are supported, including rotating target technology and the 450kV microfocus source, in addition to the full range of detectors.
The package comes with pre-calibrated artefact five-groove wedge phantom and customized bracketry with quick-change adapters that allow the operator to secure the phantom in the right positions. Dedicated software performs all necessary functions, including artefact manipulation, image collection and data analysis, and then generates a detailed report. The streamlined workflow is meant to relieve the operator of manual intervention and simplify the procedure such that it can be carried out by an operator who knows little about ASTM E2737 or X-ray CT.
Data is obtained on nine detector parameters: spatial resolution, contrast sensitivity, material thickness range, signal-to-noise ratio, signal level, image burn-in, image lag, offset value and bad pixel distribution.
The long-term performance and stability of the detector can be tracked throughout its service life. Consistency can be compared with a user-defined baseline and customizable thresholds and warnings. Results from all nine ASTM E2737 tests are stored every time a suite of measurements is made so they can be interrogated at any time. Graphical and tabular presentation of the results aids visualization.
