Abstract: A method is providedfor automatically generating a mode of presentation for data collected and produced during an imaging examination for which an examination report is done by an operator in charge of said examination, including: analyzing contextual information related to examination, analyzing data contained in the examination report, eliciting and producing relevant information from and within the collected and produced data, based on results of the contextual information analysis and of the report data analysis, and displaying the relevant information, in a simplified multi-dimensional manner as an interactive visual imaging report. Contextual information includes information on the behavior of the operator while achieving and reporting the examination. Interactive Visual Imaging Reports (IVIR) are automatically generated, as computed multi-dimensional and multi-scale objects, from native images and information collected during the image acquisition and interpretation process.

Abstract: A system for improving sensor-based decision making provides for the automatic submission of data obtained locally from instrumentation (such as image data) together with the interpretation of that data, which can be the output of some software which has been checked and possibly corrected by a user according to his/her expertise, to a remote database via an internetwork. The submission to the remote database is preferably automatic so that the remote database grows over time. The local site can access the remote database to retrieve information to assist in interpretation of the locally produced data (for example similar images and their corresponding interpretations), or can retrieve updated or improved software or parameters improving the software used for processing the data. The information on the remote database can also be reprocessed by software agents to provide statistical information based on information from a variety of such local sites.

Abstract: A method of computing a contour, such as the endocardial boundary in an ultrasound long-axis view of the heart, is disclosed. A plurality of points are input, each point being indicative of a predetermined landmark point in the image. A preliminary contour is then derived based on the input points and a known average contour shape which has been obtained from a database of contours derived from previous images. Finally, the preliminary contour is deformed to fit features identified in the image by a feature-extraction algorithm, to obtain the computed contour.

Abstract: A process for presenting information in a multimedia file from a query implemented by a user on an open computer network including a multiplicity of computer terminals enabling transmission of graphical data displayed in multimedia files, the process including selecting at least one image comprising an object to be retrieved, adaptively analyzing a global image to isolate a zone of interest comprising a graphical element which is an object of a query and calculating a set of visual signatures for each object, comparing visual signatures of extracted objects and images contained in the multimedia files to find similar objects stored in the multimedia files, and constructing a file including a set of responses resulting from the comparison.

Abstract: An electronic processing device receives sets of image data representing respectively sequential three-dimensional digital images of the same region. This device comprises means capable of defining a three-dimensional shape of interest on the basis of at least one of the sets of image data, and of extracting from each set image data representing characteristic points of the shape of interest, processing means for establishing on the basis of the image data of the contours a spatial-temporal planispheric transformation making it possible to pass from characteristic points extracted from one image to the characteristic points extracted from another image of the sequence, and means for displaying selected motion data derived from the parameters of the transformation.
