    摘要: A method for training a computer system for automatic detection of regions of interest includes receiving patient records. For each of the received patient records a text field and a medical image are identified from within the patient record and the medical image is automatically segmented to identify a structure of interest. The text field is searched for one or more keywords indicative of a particular abnormality associated with the structure of interest. The medical image is added to a grouping representing the particular abnormality when the text field indicates that the patient has the particular abnormality and the medical image is added to a grouping representing the absence of the particular abnormality when the text field does not indicate that the patient has the particular abnormality. The groupings of medical images are used to automatically train a computer system for the subsequent detection of the particular abnormality.

    摘要: In a method for detecting combustion misses in cylinders of a combustion engine in part-engine operation in which only some of the cylinders are operated by the injection of fuel, a positional angle of the crankshaft is assigned to an angle segment; each angle segment is assigned to the particular cylinder which predominantly provides the torque for moving the crankshaft through the angle segment; an irregular running datum is determined as a function of a difference of segment pass-through times of immediately successive angle segments; and a combustion miss is detected if the irregular running datum exceeds or undershoots a limit value. In part-engine operation, the irregular running datum is determined only for two successive angle segments that are assigned to a combusting cylinder and to a non-combusting cylinder.

    摘要: A computer-implemented system for searching a plurality of images for an image of interest including a database of semantic image representations corresponding to the plurality of images, wherein the semantic image representations link a semantic model of clinical properties, a syntactic model of high level image properties and an image vocabulary of low level image properties, a set of queries associated with the semantic image representations, and a semantic search engine, embodied as computer readable code executed by a processor, for receiving a search query, selecting at least one of the set of queries based on the search query, and searching the plurality of images for the image of interest by comparing the plurality of images against the semantic image representations associated with a selected query.
