    • A system and method for performing auto-focusing operations for tomosynthetic reconstruction of images are provided. More specifically, embodiments of the present invention provide a system and method for efficiently computing the gradient of one or more depth layers of an object under inspection, wherein such gradients may be used in performing auto-focusing operations to determine a depth layer that includes an in-focus view of a feature that is of interest. In at least one embodiment, a method is provided that comprises capturing detector image data for an object under inspection, and using the detector image data for computing gradient information for at least one depth layer of the object under inspection without first tomosynthetically reconstructing a full image of the at least one depth layer.
    • 提供了一种用于执行图像重建的自动聚焦操作的系统和方法。 更具体地,本发明的实施例提供了一种用于有效地计算被检查物体的一个或多个深层的梯度的系统和方法,其中这种梯度可用于执行自动聚焦操作以确定深度层,其包括 焦点视图中的一个功能是感兴趣的。 在至少一个实施例中,提供了一种方法,其包括捕获检测对象的检测器图像数据,并且使用检测器图像数据来计算被检查物体的至少一个深度层的梯度信息,而无需首先合成重建完整图像 的至少一个深度层。
