Abstract: An electronic processor (14) is programmed to perform integration (16) of N anonymized healthcare databases (10). For in a pair of databases (i,j) of the N anonymized healthcare databases, a set of features is identified (44) each contained in both databases i and j of the pair of databases (i,j). A conversion table is generated (46, 48) that matches patients of the pair of databases based on patient similarity measured by the set of features. The identifying and generating operations are repeated (50) for each unique pair of databases of the N anonymized healthcare databases to generate N(N 1)/2 conversion tables (20). The electronic processor is further programmed to perform a patient data retrieval process (18) which receives a patient ID of a patient in one of the N anonymized healthcare databases and retrieves patient data for the patient contained in the N anonymized healthcare databases using the N(N?1)/2 conversion tables.

Abstract: A multi-dimensional data set assigns data values to positions in a multi-dimensional geometrical space. A visualization is derived from the multi-dimensional data set, for example, by way of a volume or surface rendering technique. The visualization is reproduced on a display and parts that have been missed in the display are detected and indicated. For example, a new representation is made on the basis of the detected missed parts, for example, from another point of view and/or another field of view.
