  • Patent number: 9858892
    Abstract: A method, a computing device and a computer program product are provided to identify an instance in which a pixel visibility loss condition exists following window leveling. In the context of a method, window and level values and corresponding minimum and maximum values for a window are identified. The method then determines whether the pixel visibility loss condition exists based upon one or more of the window and level values, the minimum value or the maximum value. In this regard, the method determines whether a pixel visibility loss condition exists by determining whether there is a gray scale loss, a gray scale compression or a lack of perceptible distinctiveness between pixels within the window. In an instance in which the pixel visibility loss condition exists, the method causes an indication to be provided to a user.

  • Publication number: 20170286564
    Abstract: Apparatuses, methods, and computer program products are provided for extracting data from a data platform using a generic extraction code that derives relationships between different items of data based on the code structure itself (e.g., the structure of the stored data) to determine the relevant topic records for extraction. The extraction code is instantiated using the requested data type by calling a generic extraction code, accessing relationship data associated with serialized data stored in a data platform using the generic extraction code, such as with reference to an ontology library of the API. A type of a data item and a relationship of the data item with other data items stored in the data platform may thus be determined based on a structure of the serialized data accessed. A requested data item is then extracted from the data platform using the instantiated extraction code.
