Method for generating a medical image of an object, wherein at least one emission source and at least one detector of a medical imaging system are arranged relative to one another and the radiation from the emission source can be attenuated by an object and the attenuated radiation is detected by the detector and the radiation detected by the detector is used for the generation of the medical image, having the following steps: a.) Independent positioning of the emission source and of the detector relative to one another and in respect of the object for each object irradiation, wherein the relative position and alignment of the emission source and of the detector to a freely selectable centre of rotation is effected using at least one positioning element, wherein at least a part of the object can be arranged between the emission source and the detector and at least a part of the radiation from the emission source is detected by the detector; b.) Determination of the respective position of the emission source and of the detector for each object irradiation; c.) Generation of a three-dimensional reconstruction volume in at least one overlap area of at least two object irradiations (90, 91) taking into consideration the respective position of the emission source and of the detector for each object irradiation (90, 91); d.) Generation of a volume image data record on the basis of the three-dimensional reconstruction volume taking into consideration the associated positions of the emission source and of the detector for each object irradiation (90, 91), wherein the emission source and the detector are arranged in respect of one another for each object irradiation (90 to 99) such that the object irradiations (90 to 99) form at least two overlap areas and thus at least two three-dimensional reconstruction volumes (40, 41) of the object, wherein based on the three-dimensional reconstruction volumes (40, 41) volume image data records (50, 51) are generated in each case, wherein the volume image data records (50, 51) formed in this way are combined by means of an image stitching method to form a complete volume image data record; e.) Generation of the medical image relative to a predetermined section plane of the volume image data record. a.)
