    Abstract: Es wird ein System zum Anzeigen einer Vielzahl von registrierten Bildern beschrieben. Eine erste Ansichtsfenstereinheit (1) zeigt eine Darstellung eines ersten Bilddatensatzes (4) in einem ersten Ansichtsfenster (201) an. Eine zweite Ansichtsfenstereinheit (2) zeigt eine Darstellung eines zweiten Bilddatensatzes (5) in einem zweiten Ansichtsfenster (202) an. Eine Positionsangabeeinheit (7) befähigt einen Benutzer, eine Position in dem im ersten Ansichtsfenster (201) angezeigten ersten Bilddatensatz (4) anzugeben, um eine vom Benutzer angegebene Position zu erhalten. Eine Übereinstimmungspositionsermittlungseinheit (8) ermittelt eine mit der vom Benutzer angegebenen Position übereinstimmende Position in dem zweiten Bilddatensatz (5) basierend auf Übereinstimmungsinformationen (9), die Positionen in dem ersten Bilddatensatz (4) auf hiermit übereinstimmende Positionen in dem zweiten Bilddatensatz (5) abbilden, um eine übereinstimmende Position in dem zweiten Bilddatensatz (5) zu erhalten. Die zweite Ansichtsfenstereinheit (2) zeigt eine Angabe der übereinstimmenden Position im zweiten Ansichtsfenster (202) an.

    Abstract: Coronary artery segmentation is a crucial task in cardiac CT image processing. This is often a tedious task performed manually by an operator. According to the present invention, a method is provided which combines data from multiple cardiac phases during the segmentation process in order to deliver a complete and continuous coronary vessel tree. Advantageously, this may allow for an improved visualization and segmentation of vessels, for example, in coronary CTA.

    Abstract: A system for displaying a plurality of registered images is disclosed. A first viewport unit (1) displays a representation of a first image dataset (4) in a first viewport (201). A second viewport unit (2) displays a representation of a second image dataset (5) in a second viewport (202). A position indication unit (7) enables a user to indicate a position in the first dataset (4) displayed in the first viewport (201), to obtain a user-indicated position. A corresponding position determining unit (8) determines a position in the second image dataset (5) corresponding to the user-indicated position, to obtain a corresponding position in the second image dataset (5), based on correspondence information (9) mapping positions in the first image dataset (4) to corresponding positions in the second image dataset (5). The second viewport unit (2) displays an indication of the corresponding position in the second viewport (202).

    Abstract: The present invention relates to a method for performing computer-aided detection (CAD) of a disease, e.g. lung tumours, on a medical image data set (20) from a imaging modality, such as MRI or CT. Initially, there is perform a segmentation of the medical image data set (20) using an anatomical model. Secondly, the segmented data is analyzed for characteristics of the disease resulting in a set of analysis data (25), and finally the set of analysis data (25) is evaluating with respect to the disease. At least one of these steps comprises as an input a position dependent probability (P_r) for the disease. The invention isadvantageous in that more efficient computations can be performed because the degree ofanalysis in a certain region of the part of the patient, e.g. the lung, can be adjusted or tailored to the level of probability of the disease in the that region. It is thereby possible to increase computational speed and thereby diseases like cancer, in particular cancer nodules in the lungs, can be more effectively found from medical image analysis.
