The present invention, in one form, is an imaging system which, in one embodiment, utilizes scan data and DAS input signals to determine image quality. More specifically, and in one embodiment, by generating a ratio of data from two scans, a group of non-conforming detector cells may be identified. In addition, by comparing scans performed at different time frames, a trend of image quality is also determined. In addition, a group of non-conforming DAS channels may be identified by applying a range of known input signals. By comparing the an absolute gain ratio, the DAS performance is determined.
