System for evaluating the scan quality of a scanner and a method thereof

A computer-implemented method for evaluating a scan quality of an X-ray scanner for scanning cargo, the scanner adapted to scan a test piece comprising a plurality of test panels or test elements, each of the plurality of test panels or test elements is designed to test a pre-determined scan quality of the scanner, the method comprising:

• receiving a plurality of scanned images of the plurality of test panels or test elements of the test piece from the scanner, the plurality of scanned images for evaluating a plurality of the pre-determined scan qualities of the scanner,
• displaying the plurality of scanned images,
• generating a first plurality of score values for the plurality of pre-determined scan qualities of the scanner based on the plurality of scanned images,
• displaying an evaluation input interface configured to receive user evaluation input based on the evaluation of the plurality of scanned images, and
• generating a second plurality of score values for the plurality of pre-determined scan qualities based on the user evaluation input of the plurality of scanned images,
• retrieving a plurality of pre-determined first threshold score values and a plurality of pre-determined second threshold score values and comparing the first plurality of score values and the second plurality of score values against the plurality of pre-determined first threshold score values and the plurality of pre-determined second threshold score values respectively, and
• generating a failed signal if one or more of the first plurality of score values is lower than the plurality of pre-determined first threshold score values or one or more of the second score values is lower than the plurality of pre-determined second threshold score values,
• wherein the first plurality of score values and the second plurality of score values are utilized to evaluate the scan quality of the scanner.

A non-transitory computer readable storage medium comprising instructions, wherein the instructions, when executed by a processor in a system, cause the system to:

• receive a plurality of scanned images of a plurality of test panels or test elements of a test piece from a scanner, wherein each of the plurality of test panels or test elements is designed to test a pre-determined scan quality of the scanner, the plurality of scanned images for evaluating a plurality of the pre-determined scan qualities of the scanner,
• display the plurality of scanned images,
• generate a first plurality of score values for the plurality of pre-determined scan qualities of the scanner based on the plurality of scanned images,
• display an evaluation input interface configured to receiving user evaluation input based on the evaluation of the plurality of scanned images,
• generating a second plurality of score values for the plurality of pre-determined scan qualities based on the user evaluation input of the plurality of scanned images,
• retrieving a plurality of pre-determined first threshold score values and a plurality of pre-determined second threshold score values and comparing the first plurality of score values and the second plurality of score values against the plurality of pre-determined first threshold score values and the plurality of pre-determined second threshold score values respectively, and
• generating a failed signal if one or more of the first plurality of score values is lower than the plurality of pre-determined first threshold score values or one or more of the second score values is lower than the plurality of pre-determined second threshold score values,
• wherein the first plurality of score values and the second plurality of score values are utilized to evaluate the scan quality of the scanner.
