摘要： A method, apparatus and computer program product are provided for constructing a diagnostic network model in a more efficient and timely manner and with improved consistency. A structured electronic representation of a document is automatically reviewed to identify the symptoms experienced by the complex system, the plurality of components of the complex system and the causal relationships between a failure of the respective components and the occurrence of the various symptoms. Respective probabilities can be associated with the causal relationships between the symptoms and the failure of the various components. A network model, such as a Bayesian network model, may then be automatically constructed to represent the symptoms, the components, the causal relationships between failure of the components and exhibition of the symptoms, and the probabilities of the respective causal relationships.

摘要： Disclosed herein is a radiographic imaging system which performs system performance monitoring by (1) using automatic exposure control (AEC) components to predict the average image gray level; (2) obtaining measured average image gray levels from the portions of the X-ray detector situated in the X-ray shadow of the AEC components; and then (3) comparing the predicted and measured values. The predicted values are determined by use of a prediction model which is modified by a learning system over successive exposures to provide more accurate predictions. After the learning system has sufficiently developed the prediction model, the error between the predicted and measured gray level values may be monitored in later exposures and an error routine can be activated if the error exceeds a predetermined threshold. In this case, the error may indicate that system components in the imaging chain (e.g., the detector or AEC components) require maintenance.
摘要翻译：本文公开了一种射线成像系统，其通过（1）使用自动曝光控制（AEC）分量来预测平均图像灰度级来执行系统性能监视; （2）从位于AEC组件的X射线阴影中的X射线检测器的部分获得测量的平均图像灰度; 然后（3）比较预测值和测量值。预测值通过使用由学习系统对连续曝光进行修改以提供更准确的预测的预测模型来确定。在学习系统充分发展了预测模型之后，可以在稍后的曝光中监视预测和测量的灰度值之间的误差，并且如果误差超过预定阈值，则可以激活错误例程。在这种情况下，错误可能表明成像链中的系统组件（例如，检测器或AEC组件）需要维护。
