    Abstract: Systems and methods are provided for offset correction of images from a flat panel detector. In some embodiments, the apparatus and method develops one or more offset maps, acquired during system idle, for the imaging system at a plurality of exposure windows. In some embodiments, exposure parameters acquired for the imaging system before image acquisition are used to select an offset map to subtract from subsequent X-ray images. In some further embodiments, executable instructions are disclosed for directing a processor to compile one or more offset map and exposure parameters to subtract based on a selected offset map noise elements from X-ray images and thereby minimizing the time between image acquisition and display of processed images.

    Abstract: 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.

    Abstract: 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.

    Abstract: An X-ray imaging method includes in a digital X-ray detector including an array of discrete picture elements each including a photodiode and a transistor, applying a first voltage to the transistors of the discrete picture elements. The method also includes preparing for acquisition of X-ray image data by sampling data from the discrete picture elements while applying a second voltage to the transistors of the discrete picture elements not then being sampled, the second voltage being more negative than the first voltage. The method further includes receiving X-ray radiation on the detector from a source. The method yet further includes sampling X-ray image data from the discrete picture elements while applying the second voltage to the transistors of the discrete picture elements not then being sampled.

    Abstract: A method and System for identifying repeat clip instances in video data. The method comprises partitioning the video data into ordered video units utilising content-based keyframe sampling, wherein each video unit comprises a sequence interval between two consecutive keyframes; creating a fingerprint for each video unit; grouping at least two consecutive video units into one time-indexed video segment; and identifying the repeat clip instances based on correlation of the video segments. The method can be used for both discovering unknown repeat video clips and identifying instances of known repeat video clips automatically. The method can be used to identify short repeat video clips from less than a second long to a few minutes, such as tv station logos, program logos, tv commercials which are widely used in news video and other daily broadcasting programs.
