The method involves determining respective positions of an emission source and a detector in object irradiations (90, 91). A three-dimensional reconstruction volume (40) is produced within an overlapping area of the object irradiations under consideration of the respective position of the emission source and the detector for each object irradiation. A volume image data set is produced based on the produced three-dimensional reconstruction volume. Medical images are generated with respect to a given section plane of the volume image data set. An independent claim is also included for a medical image recording system comprising an emission source.
