Abstract
In a registration method for navigation-guided medical interventions using a position acquisition system, an X-ray device and an X-ray calibration phantom having X-ray-positive marks, the coordinates of marks of the X-ray calibration phantom that are present in the measurement volume of the X-ray device and imaged in the reconstructed volume are determined in a coordinate system allocated to the measurement volume of the X-ray device) and in a coordinate system allocated to the position acquisition system. The coordinate transformation between the coordinate system allocated to the measurement volume and the coordinate system allocated to the position acquisition system is determined on the basis of the coordinates of the X-ray-positive marks in the coordinate system allocated to the measurement volume and on the basis of the coordinates of the X-ray-positive marks in the coordinate system allocated to the position acquisition system.
