Method for forming an image of an object with the following method steps: - providing data about the object by a first data processing device; - providing at least a first data record by the first data processing device, the first data record having first data, which comprise the following: (i) at least a first imaging parameter (12A, 13A, 14A, 15A, 16A, 17A, 18A, 19A) of a first imaging system with which the data about the object have been generated, and/or (ii) at least a second imaging parameter (12B, 13B, 14B, 15B, 16B, 17B, 18B, 19B) of a second imaging system with the properties of which an image of the object is intended to be represented on a display unit on the basis of the data about the object; - loading the first data record from the first data processing device into a second data processing device; - loading a second data record from a data memory into the second data processing device in dependence on the first data record loaded into the second data processing device, the second data record having second data, which comprise the following: (i) modification data for modifying imaging errors in dependence on the first imaging parameter (12A, 13A, 14A, 15A, 16A, 17A, 18A, 19A) of the first imaging system and/or (ii) modification data for modifying the data about the object in dependence on the second imaging parameter (12B, 13B, 14B, 15B, 16B, 17B, 18B, 19B) of the second imaging system; - generating a processing data record on the basis of the second data record or detecting that the second data record is being used as the processing data record; and - forming a two-dimensional output image of the object by processing the data about the object by using the processing data record, the output image having a predeterminable number of output image pixels; wherein - the first data record loaded from the first data processing device into the second data processing device has user identification data; and wherein - checking is carried out on the basis of the user identification data by using the first data processing device and/or the second data processing device to ascertain whether an authorization of use exists for using the second data record with the first data processing device and/or the second data processing device, and wherein the processing data record is generated only if the authorization of use exists. - providing data about the object by a first data processing device; - providing at least a first data record by the first data processing device, the first data record having first data, which comprise the following: (i) at least a first imaging parameter (12A, 13A, 14A, 15A, 16A, 17A, 18A, 19A) of a first imaging system with which the data about the object have been generated, and/or (ii) at least a second imaging parameter (12B, 13B, 14B, 15B, 16B, 17B, 18B, 19B) of a second imaging system with the properties of which an image of the object is intended to be represented on a display unit on the basis of the data about the object; - loading the first data record from the first data processing device into a second data processing device; - loading a second data record from a data memory into the second data processing device in dependence on the first data record loaded into the second data processing device, the second data record having second data, which comprise the following: (i) modification data for modifying imaging errors in dependence on the first imaging parameter (12A, 13A, 14A, 15A, 16A, 17A, 18A, 19A) of the first imaging system and/or (ii) modification data for modifying the data about the object in dependence on the second imaging parameter (12B, 13B, 14B, 15B, 16B, 17B, 18B, 19B) of the second imaging system; - generating a processing data record on the basis of the second data record or detecting that the second data record is being used as the processing data record; and - forming a two-dimensional output image of the object by processing the data about the object by using the processing data record, the output image having a predeterminable number of output image pixels; wherein - the first data record loaded from the first data processing device into the second data processing device has user identification data; and wherein - the first data record loaded from the first data processing device into the second data processing device has user identification data; and wherein - checking is carried out on the basis of the user identification data by using the first data processing device and/or the second data processing device to ascertain whether an authorization of use exists for using the second data record with the first data processing device and/or the second data processing device, and wherein the processing data record is generated only if the authorization of use exists.
