DETECTION OF MUTATION BY RESOLVASE CLEAVAGE

A system, apparatus and method for testing the functional components of an electronic digital imaging system is described. The system includes apparatus for image acquisition, storage, display, communication and printing. The system relies on a closed loop analysis to test system components by measuring a set of statistical image quality metrics. The expected set of statistics are in the form of special purpose features stored as a data set representative of an expected reference object. The closed loop analysis measures, for example, the quality of the printing component of the system by ouputting a copy of the expected reference image, using the acquisition component to input the copy of the excepted reference image, and then comparing the statistics against threshold values representative of an ideally operating component. The comparison of statistics against the threshold values provides a go/no-go measure of component performance and can indicate sources of system degradation. The image quality metrics is known as a metrics set which contains a comprehensive set of tests regarding primary modes of image quality degradation: pixel value integrity, pixel location integrity (geometric distortion) and spatial resolution. The metrics set allows for the automatic execution of a large number of image quality measurements and a reduction of the resulting test data to a manageable result so that a simple go/no go result may be given to the system operator. In addition, the metrics set is useable in indicating and locating system faults based upon the analysis data for field service personnel.
