ABSTRACT:
The invention relates to a method of determining the spatial transformation between an object which is three-dimensionally reproduced by a data set and the object itself. According to the method at least one X-ray image of the object is formed. A pseudo-projection image is calculated for a part of the volume represented by the data set, said pseudo-projection image being compared with the X-ray image. The parameters on which the calculation of the pseudo-projection image is based are varied until optimum registration is achieved.
