摘要： A diagnostic imaging system in an example includes a high frequency electromagnetic energy source, a detector, a data acquisition system (DAS), and a computer. The high frequency electromagnetic energy source emits a beam of high frequency electromagnetic energy toward an object to be imaged. The detector receives high frequency electromagnetic energy emitted by the high frequency electromagnetic energy source. The DAS is operably connected to the detector and programmed to employ a threshold to trigger a filter operation on a pixel, in a basis material decomposition (BMD) image of a plurality of BMD images, through comparison of an actual noise ratio between a pair of BMD images, of the plurality of BMD images, to a theoretical BMD noise ratio value. The computer is programmed to employ a correlation in noise distribution of the plurality of BMD images to reduce image noise in the plurality of BMD images.

摘要： Count rates may be obtained from one or more subpixels for a given pixel in an imaging system detector. Count rates may be obtained from individual subpixels, or may be from electronically binned subpixels at least in part in various subpixel arrangements where a selected subpixel arrangement may be adaptively set according to a detected count rate. For lower count rates, two or more subpixels may be electronically binned together and the counts may be obtained from the binned subpixels, for example to mitigate a charge sharing effect. For higher count rates, the count rates of a greater number of subpixels may be individually obtained, for example to mitigate a pulse pile-up effect. Detective quantum efficiency may be optimized over a wider range of photon flux rate via the adaptive subpixel arrangement.
