1. Method for deriving a magnetic resonance image of an object when placed in a stationary and substantially homogeneous magnetic main field, comprising repeatedly exciting said object to emit magnetic resonance signals and sampling the emitted magnetic resonance signals in the presence of a read gradient superimposed on said main field, which read gradient is rotated to radially scan through frequency space, determining a first frequency image of said object on radius and angle coordinates, and performing the steps of: a) determining an edge image in image-space, b) deriving from said edge image a correction image in image-space with pixel values derived from pixel values of said edge image and a predetermined probability function of edge image values, c) determining a corrected frequency image in frequency-space, d) Fourier transforming said corrected frequency image to image-space.
