    摘要： Briefly, in accordance with one or more embodiments, 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.

    摘要翻译： 简而言之，根据一个或多个实施例，可以从成像系统检测器中的给定像素的一个或多个子像素获得计数率。 可以从各个子像素获得计数速率，或者可以至少部分地根据检测到的计数速率自适应地选择所选择的子像素排列的各种子像素排列从电子分组的子像素获得。 对于较低的计数率，可以将两个或更多个子像素电子地分组在一起，并且可以从二进制子像素获得计数，例如以减轻电荷共享效应。 对于更高的计数率，可以单独获得更多数量的子像素的计数率，例如以减轻脉冲堆积效应。 可以通过自适应子像素排列在更宽的光子通量速率范围内优化探测量子效率。
