Claim One:
1. A method for the oriented depiction of recordings of a region to be imaged which is recorded in at least two recording steps using a navigation system comprising the following features: an x-ray device comprising an x-ray detector and an x-ray source arranged opposite to the x-ray detector, the x-ray detector and x-ray source movable with respect to each other and with respect to the region to be imaged; a stereo recording system; marker devices assigned to the x-ray detector and the region to be imaged, said marker devices at least partially detectable by the stereo recording system; wherein the method comprises the following steps: a) initiating a first recording of a first portion of the region to be imaged when the x-ray source and x-ray detector are in a first position, said initiating the first recording including outputting a first control signal; b) based on the first control signal, the stereo recording system detecting first marker positions of the marker devices on the x-ray detector and the region to be imaged; c) storing data concerning the first marker positions; d) correlating, with computer assistance, the data concerning the first marker positions with image points of the x-ray recording in order to register the x-ray recording; e) ascertaining and storing a first position of the x-ray source relative to the detector; f) determining, with the aid of the registration, the position of the x-ray source in the coordinate system of the region to be imaged, and storing the determined position of the x-ray source; g) moving the x-ray detector and the x-ray source relative to the region to be imaged into a second position for a second recording, wherein changes in the position of the x-ray detector are detected during the movement, and a second position of the x-ray source is determined by means of the first relative position; h) initiating a second recording of a second portion of the region to be imaged when the x-ray source and x-ray detector are in the second position, said second portion axially shifted relative to said first portion, and wherein said initiating the second recording includes outputting a second control signal; i) based on the second control signal, the stereo recording system detecting second marker positions of the marker devices on the x-ray detector and the region to be imaged; j) correlating, with computer assistance, the data concerning the second marker positions with image points of the x-ray recording in order to register the second x-ray recording; k) ascertaining an additional position from the second position and the first position; l) based on the additional position, registering and displaying the recordings in a superimposed way.
