摘要：
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.
