The invention relates to a method and a device for determination of an optimum direction of projection or position for recording a number of two-dimensional projection images of an object of interest, with the two-dimensional projection images being recorded by rotation or translation of an imaging system around the object. Inventively the process is as follows: a) estimating a position of the object at a point in time; b) determining at least one optimum imaging view from which the optimum direction of projection and/or position is produced, for the position estimated under a) with the aid of previously determined measurement. Preferably the measurement is expressed as a function of a transformation which is described by a spatial object-imaging system relationship.
