Abstract:
1. Method for canceling the impact of the physical property variability of quality control targets on the image quality performance of a digital imaging system comprising: obtaining image data for quality control analysis of a first quality control target identified by a unique serial number; determining raw image quality performance parameters for the image data; obtaining quality control target specific physical property data for the first quality control target by reference to its unique serial number, the quality control target specific physical property data characterizing deviations in physical properties between the first quality control target and a second reference quality control target; obtaining behavior models for the image quality performance parameters under analysis; obtaining image quality performance acceptance criteria; generating physical property neutralized image quality performance parameters by correcting the raw image quality performance parameters using the behavior models and the quality control target specific physical property data to correct for differences between the first quality control target and the second reference quality control target; comparing the physical property neutralized image quality performance parameters to the image quality performance acceptance criteria to determine the image quality performance of the digital imaging system; and taking images of objects with the digital imaging system.
