The invention relates to a method of tomographic imaging, and in particular a CT or MR method, for the repetitive production of diagnostic slice images of a part of a patient's body. To allow a geometrical transformation ( 2 ) to be determined, current reference slice images ( 1 ) of the part of the body, which are brought into agreement with earlier reference slice images ( 3 ) of the part of the body are first made in this case. Current imaging parameters ( 5 ) are then calculated for a current diagnostic slice image ( 6 ) by transforming earlier imaging parameters by the geometrical transformation ( 2 ) previously determined. To give greater accuracy and, at the same time, a short image-making time, the image proposes that at least two current reference slice images ( 1, 1' ) be made, whose image planes are preset in such a way that their relative positions and orientations in three dimensions agree with the relative positions and orientations in three dimensions of the earlier reference slice images ( 3, 3' ), the geometrical transformation ( 2 ) being determined in such a way that it brings all the current reference slice images ( 1, 1' ) in agreement with the corresponding earlier reference slice images ( 3, 3' ) simultaneously.
