1. A data processing system, comprising at least one computer having at least one processor configured to execute a computer-implemented medical data processing method for determining the spatial position of medical objects, the data processing method comprising the steps of:
acquiring, at the processor and via a medical tracking system comprising a sensor array, first position data which comprise first position information describing the spatial position of an object within a first co-ordinate system positionally assigned to said sensor array which is configured to determine the spatial position of at least one tracking marker attached to the object; acquiring, at the processor, first transformation data which comprise first transformation information describing a transformation of the object's position from the first co-ordinate system into a second co-ordinate system positionally assigned to an inertial sensor array which is attached to the medical tracking system's sensor array and configured to sense any motion of the medical tracking system's sensor array within an inertial co-ordinate system positionally assigned to a treatment room which accommodates the object; acquiring, at the processor and on the basis of the first position data and the first transformation data, second position data which comprise second position information describing the spatial position of the object within the second co-ordinate system; acquiring, at the processor, second transformation data which comprise second transformation information describing a transformation of the object's position from the second co-ordinate system into the inertial co-ordinate system; determining, by the processor and on the basis of the second position data and the second transformation data, inertial position data which comprise inertial position information describing the spatial position of the object within the inertial co-ordinate system. |
