Abstract: A system for support and management of search for documents is presented. The system includes a knowledge-database, query interface and communication to a database of documents to be searched. Information generated during a search session is collected by the system and is added to the knowledge-database. The information is ranked automatically according to the usage of that information by the user. During successive search session or during a search made by another user, the system uses the knowledge-database to support the users with keywords, queries and reference documents.

Abstract: A color separation scanner comprising a support arranged for mounting thereon of a two-dimensional image to be scanned and color separation sensing apparatus arranged for sensing the two-dimensional image. The color separation apparatus includes a scanning head located a fixed distance from the two-dimensional image, at least first and second objective lens assemblies and apparatus for selectively arranging each of the at least first and second objective lens assemblies in fixed locations along the optical path between the image and the scanning head.

Abstract: A color separation scanner comprising a movable support arranged for mounting thereon of a two-dimensional input picture to be scanned and color separation sensing apparatus arranged for sensing the two-dimensional input picture for providing electrical signals representing color separations of the two-dimensional picture, the color separation sensing apparatus including a scanning head having a plurality of generally parallel CCD arrays, associated with dichroic filter means and operative for simultaneous scanning of the two-dimensional input picture.

Abstract: A system for improving the performance of video cameras used in Digital Subtraction Angiography wherein the cameras have tubes comprising targets with elements in said target that correspond to pixels of an image. The method basically comprises the step of defocusing the electron beam especially during the scrubbing operation so that the electron beam impinges on more than one element at a time.

Abstract: A medical diagnostic imaging system that selectively digitizes and processes video data obtained from either a radiographic or a fluorographic source.
