我们将基于任务的评价方法应用于圆形锥束CT的图像重建。所考虑的特定任务是在已知背景中检测已知位置的微钙化;即信号精确已知/背景精确已知（SKE/BKE）检测任务。图像重建算法的检测效率的基础上进行评估。这种基于任务的度量可以应用于任何线性图像重建算法，例如FDK算法或用于圆形锥形束CT中的图像重建的其他最近的近似方法。
We apply task-based evaluation methods to image-reconstruction in circular cone-beam CT. The particular task considered is that of detection of a micro-calcification of known location in a known background; namely a signal-known-exactly/background-known-exactly (SKE/BKE) detection task. The image-reconstruction algorithms are evaluated based on efficiency for detection. This task-based metric can be applied to any linear image-reconstruction algorithm, such as the FDK algorithm or other more recent approximate methods for image-reconstruction in circular, cone-beam CT.
