摘要

Method for reconstructing a three-dimensional image data set of an examination object from two-dimensional projection images recorded with a biplane X-ray device (5), the Biplan X-ray device (5) having two receiving arrangements measuring at an angle with respect to one another with in each case one X-ray emitter (8, 9) and an X-ray detector (10, 11) and the projection images at the same time (TM) with the different recording arrangements recorded simultaneous pairs of projection images, wherein for image-based, in particular rigid, registration of the receiving arrangements to each other for at least a portion of, preferably all, simultaneous pairs on a redundancy in the projection data of the projection images based consistency measure is determined and a determination of the registry of the recording arrangements descriptive registration parameters by minimizing a by summation of the Kon consistency measures of certain consistency metrics in an optimization process.
