    Abstract: The invention relates to a method of segmenting a three-dimensional structure from a three-dimensional, and in particular medical, data set while making allowance for user corrections. The method is performed with the help of a deformable three-dimensional model whose surface is formed by a network of nodes and mashes that connect these nodes. Once the model has been positioned at the point in the three-dimensional data set at which the structure to be segmented is situated and positions of nodes have, if necessary, been changed by known methods of segmentation, any desired nodes can be displaced manually. The nodes of the model are re-calculated by making weighted allowance for the nodes that have been displaced manually.

    Abstract: The invention relates to a pointing device (40) for indicating the spatial position of markers (2) to a localization system (10). The pointing device (40) comprises a sensor (42) that detects if a definite interaction with the marker (2) takes place. The sensor (42) may for example be a pressure sensor (42) that determines if the contact force exceeds a threshold which could lead to undesired shifts of the marker (2). The pointing device (40) is used to determine the spatial coordinates of the marker (2), which can then be registered with the image coordinates of the marker (2) in a stored image, e.g. a CT-image.

    Abstract translation: 本发明涉及一种用于向定位系统(10)指示标记(2)的空间位置的指示设备(40)。 指示设备(40)包括传感器(42),其检测是否发生与标记(2)的明确相互作用。 传感器(42)可以例如是压力传感器(42),其确定接触力是否超过可能导致标记(2)的不期望的移位的阈值。 指示设备(40)用于确定标记(2)的空间坐标,然后可以将该标记(2)的图像坐标与所存储的图像(例如图像)中的标记(2)的图像坐标进行配准。 一个CT图像。
