Abstract

The invention relates to an imaging method for medical examinations, notably MR examinations, in which a set of measurement values is acquired from measuring points which are irregularly distributed in the frequency domain (or in the k-space). Before an image in the space domain is generated from these measurement values by a Fourier transformation, the measurement values must be weighted in dependence on the density of the measuring points in the frequency domain. To this end, the measurement values are weighted in conformity with the magnitude of the Voronoi cells.
