Abstract: The invention discloses a method for modifying functionality of a real-time communications system. The method comprises establishing a real-time communication session (100) between a first participant (A) and a second participant (B); responsive to detecting a trigger event, selecting a first redaction algorithm (112) of a plurality of redaction algorithms; and adding the first redaction algorithm to the real-time communication session as a virtual participant (C). The first redaction algorithm is configured to redact data appearing in a data stream to be transmitted from the first participant to the second participant during the real-time communication session.

Abstract: Presented are approaches for dynamic modification of the functionality of a RTC session including one or more data streams between participants to the real-time communication session (100). Embodiments of the present invention are therefore directed toward enabling the functionality of a RTC system to be modified, extended and/or improved while it is implementing a RTC session. Exemplary embodiments include: identifying a request for a first algorithm (A1) of a set of algorithms (A1, A2, A3); and dynamically modifying the functionality of the real-time communications session by adding the first algorithm (A1) to the real-time communication session (100) as a virtual participant employing at least one data stream out of the one or more data streams.

Abstract: The present invention relates to a system (1) and method for registration of medical image (10,11). Furthermore the invention relates to a computer program (5) for registration of medical images (10,11), when the computer program (5) is executed in a computer (2). In order to provide a more accurate registration transformation of medical images it is suggested to detect insufficiently similar areas (14,14?,25,26) and to exclude them from the registration by means of an exclusion mask (22,24,27) that indicates which pixels/voxels should not be included during the registration process.

Abstract: A CT imaging apparatus (2) for providing a 2D representation of 3D image data representing a pulmonary vessel tree of a patient is disclosed. The apparatus comprises X-ray sources (6) and detectors (8) arranged in pairs for generating 3D image data representing a plurality of positions along lumen branches of the vessel tree and for receiving 3D image data representing at least one anatomical property at each of the locations. A processor (20) processes the 3D image data to provide 2D image data displayed on a display device (24) such that each lumen branch is represented by a line, and the color of each portion of a line representing one of the positions varies in dependence upon the anatomical property being measured.

Abstract: The present invention relates to a method of image registration comprising the steps of, a) providing at least first image data and second image data, b) selecting of sub-volumes of the first and the second image data, c) performing a registration for each one of the sub-volumes, each registration providing a transformation parameter set, d) performing a global registration for the first and second image data, the global registration providing a global transformation parameter set, e) comparing one of the transformation parameter sets to other transformation parameter sets and/or to the global transformation parameter set for identification of an outlier transformation parameter set of the transformation parameter sets, f) outputting of a signal being indicative of the sub-volume of the outlier transformation parameter set.

Abstract: An automatic quantitative analysis method is developed so as to analyze perfusion cardiovascular images. First the image registration per data set is performed so as to compensate for translation and rotation of the target region of interest over the acquisition time. Next a parameter, for example, a maximum intensity projection, is calculated in order to average out misalignments of the target region of interest within each data set. Finally, parameter registration is performed to calculate the co-ordinate translation matrix between the anatomically corresponding pixels within the target region of interest. The co-ordinate translation matrix can also be used to calculate local perfusion values.
