Standards Development
This standard applies to Spectral Image types based on data provided by ct scanner with dual or multi-energy imaging.
The purpose of this standard is to provide selected methods and metrics for aspects of imaging performance associated with the following spectral image type (if available):
• Single kVp like image (3.5)
• Virtual Monoenergetic Image (3.1)
• Virtual non-contrast image (3.2)
• Iodine concentration image (3.3)
• Electron density image (3.4)
The tests presented in this document do not provide comprehensive technical performance evaluation of CT Spectral Imaging.
The results obtained using the methods of this document do not replace CT spectral imaging performance specifications and testing protocols as provided by manufacturer.
Additionally, phantom requirements are specified accordingly. Spectral image types not listed above are not covered by this document, as explained in Annex D.
