Claim One:
1. Method for creating and using a serial-numbered quality control (QC) target comprising: generating a unique serial number that is specific to the QC-target, wherein different QC-targets each receive different and unique serial numbers; measuring a thickness, length or shape of the QC-target to generate measured physical property data for components of the QC-target; creating a data set comprising the measured physical property data of the QC-target components; encoding said QC-target with said serial number and said physical property data, wherein the physical property data are incorporated into the QC-target by: hardcoding the data in- or outside the QC-target by modifying the local x-ray absorption properties of the QC-target; obtaining an x-ray image of the QC-target in a radiography system; decoding and obtaining the physical property data from the QC-target by analyzing the x-ray image to extract the data set and then decoding the data set to obtain the measured physical property data; and using the x-ray image and the physical property data decoded from the QC-target to assess a performance of the radiography system.
