    Abstract: It is an object of the invention to provide a more convenient system 40 for visualizing a certain object from a range of viewing angles in a scene comprising a plurality of objects at multiple viewing angles with some of the objects being view-obscuring objects, capable of identifying the view-obscuring objects and adjusting their transparency for obtaining a better view of the certain object comprising the interesting anatomical features. To achieve this object, the invention provides a system comprising segmenting means 41 for segmenting a multidimensional image data set into the plurality of objects, first selecting means 42 for selecting the certain object from the plurality of objects, second selecting means 43 and 44 for selecting a viewing angle from the range of viewing angles, identifying means 45 for identifying a view-obscuring object that obscures the view of the certain object when the certain object is viewed from the viewing angle selected, and transparency adjustment means 45 for changing the transparency of the view-obscuring object identified.

    Abstract: High frequency signals cannot be reconstructed properly from sampled data if the sampling frequency lies below the Nyquist rate. The invention addresses this problem by choosing few additional sample points along a trajectory intersecting the region comprising the high frequency signals, such as an edge. Intermediate rendering data is used to determine the additional sample points. Therefore, according to an exemplary embodiment of the present invention, 4 adaptively chosen sample points per pixel may provide a visual quality comparable to 16 times super-sampling, but at a much lower computational cost.

    Abstract translation: 如果采样频率低于奈奎斯特速率，则高频信号无法从采样数据正确重建。 本发明通过沿着与包括高频信号的区域（例如边缘）相交的轨迹的几个附加采样点来解决这个问题。 中间渲染数据用于确定附加采样点。 因此，根据本发明的示例性实施例，每像素4个自适应选择的采样点可以提供与16次超采样相当的视觉质量，但是以低得多的计算成本。

    Abstract: A system for generating a view of a medical image comprises an input (1) for receiving information indicative of a suspected diagnosis of a patient. An input (2) for receiving a medical image of the patient. A mapper (3) for mapping the suspected diagnosis of the patient to a set of viewing parameters for viewing the medical image. A view generator (8) for providing a view of the medical image in accordance with the set of viewing parameters. A database (4) for mapping a suspected diagnosis into a set of generic viewing parameters. A transformer (5) for transforming the set of generic viewing parameters into a set of image-specific viewing parameters based on content of the medical image.

    Abstract: The invention relates to a system (100) for obtaining information relating to segmented volumetric medical image data, the system comprising: a display unit (110) for displaying a view of the segmented volumetric medical image data on a display; an indication unit (115) for indicating a location on the displayed view; a trigger unit (120) for triggering an event; an identification unit (125) for identifying a segmented anatomical structure comprised in the segmented volumetric medical image data based on the indicated location on the displayed view in response to the triggered event; and an execution unit (130) for executing an action associated with the identified segmented anatomical structure, thereby obtaining information relating to the segmented volumetric medical image data. The action executed by the execution unit (130) may be displaying a name of the segmented anatomical structure, a short description of the segmented anatomical structure, or a hint on a potential malformation or malfunction of the segmented anatomical structure. Thus, the system (100) allows obtaining valuable information relating to the volumetric medical image data viewed by a physician on the display, thereby assisting the physician in medical diagnosing.
