摘要： The invention relates to a system (100) for visualizing an object of interest comprised in a volume of an image dataset, the system comprising a path unit (110) for specifying a path in the volume of the image dataset on the basis of the object of interest, a location unit (120) for determining a location on a projection ray through the volume of the image dataset on the basis of the specified path, and a value unit (130) for computing a projected gray value corresponding to the projection ray on the basis of the determined location on the projection ray. Because the locations on the projection ray are determined based on the specified path for indicating the object of interest, the actual computation of the projection gray values may be designed and constructed to show gray values describing the object of interest while hiding gray values describing other objects, in particular occluding objects. Thus, the system of the invention is arranged for visualizing the object of interest at different viewing angles without occluding the object of interest.
摘要翻译：本发明涉及一种用于可视化包含在图像数据集的卷中的感兴趣对象的系统（100），该系统包括用于基于对象指定图像数据集的卷中的路径的路径单元（110）用于基于指定路径确定通过图像数据集的体积的投影光线上的位置的位置单元（120），以及用于计算对应于投影光线的投影灰度值的值单元（130）在投影光线上确定的位置的基础上。由于投影光线上的位置是基于用于指示感兴趣对象的指定路径来确定的，所以投影灰度值的实际计算可以被设计和构造成显示描述感兴趣对象的灰度值，同时隐藏描述其他对象的灰度值，特别是闭塞物体。因此，本发明的系统被安排用于在不遮挡感兴趣的对象的情况下以不同的视角来可视化感兴趣的对象。

摘要： In real-time three-dimensional imaging the choice of the visualization method and orientation is crucial for intervention success. The key question is what to ignore and what to show in real-time applications, where user control is not appropriate. An intervention (caused by a user) to an object of interest is visualized without the requirement of an interactive input by the user. Parameters for a visualization procedure are automatically chosen during data acquisition which may allow for an efficient tracking of the actual orientation and relative position of the structure with respect to the object of interest.

摘要： Scattered radiation has non-intuitive properties. A signalling system (28) is presented which provides a perceptible signal (34) being indicative of a predicted or measured spatial distribution of scattered radiation. An embodiment provides for easy assessment of the individual risk of scattered radiation exposure for personnel working in an environment exposed to scattered radiation. A method for predicting a distribution of scattered radiation takes into account at least one object related parameter (18) and at least one radiation related parameter (22) and, in response hereto, predicts a distribution of scattered radiation.

摘要： Medical imaging modalities generate increasingly more and very large three-dimensional data sets. According to an exemplary embodiment of the present invention, a three-dimensional data set of an object of interest is interactively visualized with a varying sampling rate in an image. Advantageously, a focus area may be moved by a user interactively during rendering, wherein the sampling rate of a particular part of the image is defined by its relative position to the focus area. Advantageously, this may allow for an improvement of an overall rendering performance.
