Abstract

The invention relates to an arrangement for assisting a percutaneous intervention, comprising an imaging system for tomographic imaging, a robot registered therewith and devices for capturing movements of the patient. A processing unit registers a 4D image dataset recorded before the intervention with a 2D or 3D image dataset of the patient which was recorded immediately before the intervention by the imaging system at a defined respiratory position. From this image data, the access path is transmitted to the robot as a function of the movements captured during recording the 4D image dataset and registration, said robot in turn, depending on the instantaneous movement data, holding the instrument on a predetermined target path and preventing the instrument from being advanced by the person if and as long as the instantaneous movement data does not match the previously recorded movement data. The arrangement reduces the risk of puncture errors.
